Cabin Fever

Cabin Fever is the 19th map released in Combat Arms. It is also a hybrid map, combining Fireteam and Quarantine elements to create a Survival concept. The UAF Double Agents who escaped the underground research center, with a "liberated" virus sample, are being hunted down by hordes of The Infected. Leading to a dead end, they take refuge in an old, abandoned building. There, the battle of life and death will continue as players hold out against wave after wave until the evac arrives.

This map is a follow-up on the events of Overdose.

Mission Objectives:

"...Attention CAC... ...surrounded by infected... ...mutating into... ...need evac pronto!

"SITREP: As the above fragmentary radio message indicates, the situation with the NEMEXIS virus has begun to spiral out of control. After “liberating” a sample of the virus from an underground research center, fireteams are being hunted by hordes of deadly mutated victims of the virus. After taking refuge in an abandoned building near the facility, teams have found that they’re trapped inside by a cloud of deadly gas being released by infected corpses. Worse, the virus has continued to mutate, morphing some infected into deadly new forms. Rescue teams have been dispatched. Fireteams are advised to do what they must to survive until they arrive. Weapons are hot, stay alive!

Mission Briefing
Since it is a map hybrid, consisting of Quarantine and Fireteam elements, Nexon uses concepts from both game modes.

Some unique characteristics of this map:
 * Your enemies are the Infected, controlled by AI and easier/harder to kill in different ways.
 * As in Quarantine, the Infected cannot use ranged attacks. They make up for this by being able to inflict high melee damage and utilizing special after-death abilities.
 * There are now multiple hordes of Infected; all of which can come in different forms.
 * There is only one area you can move around in; namely, the house itself. Further areas of the house will be unlocked after a certain number of rounds has passed.
 * You must keep the power generator downstairs on to proceed, as the Infected will occasionally disable it.
 * Messages are constantly being sent in to keep you updated on the situation
 * You must wait for evacuation to arrive.
 * Players respawn and heal a little after each round, and have their ammo replenished completely. They respawn and heal to full health after each "chapter" (cutscene).
 * The Ammo packs in Cabin Fever differ from the ones in previous missions. Regular ammo packs are for most primary weapons, usually assault rifles and shotguns. They can be noted by their color (yellow), and the icon of shells upon the pack. Grenade ammo packs are quite a bit rarer; they are for most explosives, sniper ammo, and machine gun ammo. They can be noted by their color (pink), and the icon of a grenade upon the pack. Health packs are the rarest; they are for health (obviously) and can fully heal you. They can be noted by their (green) hue, and the icon of a red cross upon the pack.

Summary
Players are trapped inside a small building, with waves of Infected approaching from all sides. The building encased by a cloud of toxic gas (which is generated by the Infected), so all players are forced to stay in the vicinity of the cabin. To "win", all waves of Infected must be survived by killing all of the attackers. To "beat" the map itself, all 20 rounds must be survived. Killed enemies may drop ammo or health from time to time, the frequency depending on the difficulty. Other types of enemies release special "after-effects" upon death (such as a toxic gas cloiud) which can harm the player even after the enemy itself has been killed.

Rounds will get increasingly difficult as time progresses, with more numerous and tougher enemies spawning each wave. At the same time, players have very limited ammo and health, and very little opportunity to evade damage. After each round, ammo is restocked, dead players get a respawn, and new info is updated. Health is partially restored; the higher the difficulty the lower the heal. (10-60 HP)

The Infected
With the advent of the newly evolved Infection, there are now 4 new "forms" of the Infected. There is the "Mauler", which is the weakest as well as the most numerous of the Infected. Similar to the Mauler is the "Charger", an Infected with explosives strapped to its chest which detonate when the Charger is killed. Next is the "Witch", an agile Infected that is extremely resilient to headshots, which drops 2-3 seemingly organic grenades that detonate about a second after the Witch is killed.

Finally, there is the "Enforcer", with a build similar to a Tank. When killed (which could take some effort), Enforcers release a extremely toxic cloud of gas. They are considered as "semi-bosses", as they are extremely hard to kill. As such, the Enforcers have gained a reputation as the most dangerous of all the Infected.

Pre-Game Preparation
Stock up on Machine Guns, or a weapons with plenty of ammo. Don't depend on explosives. If you don't like Machine Guns, get scoped Assault Rifles, Specialist Items, or Sub-Machine Guns. Headshots are instant kills if aimed correctly, or performed with the right weapons. They may not get you as much points, but you will get through the round faster by aiming for the head (Sniper Rifles are recommended). Before entering a room, decide on how you're going to try and win. Get plenty of kills (but earn less points), or get plenty of points (but earn less kills). Different strategies can get different reward results.

In a full room, you may even plan out each player's position.

Support - Everyone should always be able to provide support, but certain players must support as their main objective. Support have the duty to kill multiple Infected when they are getting close, finishing off targets, covering others (spotting), warning/helping out with the Enforcers, and helping at a breach in the doors. They should be flexible enough to leave their temporary post (usually a window)and assist other players. In the later rounds, they will have to be assigned to other jobs, as there will be new spawn points need to be covered (for example, the basement). Support can use any variety of weapons; but it is suggested you specialize in one type only. Assault Rifles, SMGs', MGs', and Shotgun combinations are recommended.

Recommended Weapons:
 * Assault Rifles - AK-47, AK74, M416, K2
 * SMGs - UMP, MP5, UZI
 * Machine Guns - Any
 * Shotguns - Just one, not recommended

Sharpshooter - Sharpshooters are a vital part of keeping the Infected at bay. They may or may not be a popular choice since they often steal, hoard, or accumulate massive kills, but they are still important. Their job is to make sure the Infected don't have a chance to blink as soon as they spawn. They must be able to get headshots as much and as soon as possible at any range. It should be noted that they are usually the most vulnerable, not having time to change from their sniping point-of-view. Always check behind you every once in a while to make sure your teammates are doing okay, or you're not getting attacked. Teamwork is important so don't abandon a Sharpshooter to get more kills. Just the same, Sharpshooters should not fully depend on a others so be prepared to fight in CQC.

Recommended Weapons:
 * Assault Rifles - M14, AUG, G36, AK-47
 * Sniper Rifles - SR-25 MSG-90, Dragunov SVD (*Note that Bolt-action rifles are NOT recommended here; they have low ammo and slow reload times. Power isn't really needed here, M24 maybe used for experinced marksmen due the well-known accuracy and follow the motto "1 shot 1 kill")
 * Machine Guns - Any

Heavy Infantry - Heavy Infantry are an extremely lethal force in combat. By far the most popular choice to combat the Infected, they often get a lot of points during a game (as opposed to kills). Infantry often mow down and hold back multiple waves at once. However, they need a lot of ammo and weaponry if they are to last long. Infantry supports the team by weakening and killing enemies without pausing to reload. This is important since a horde will not wait for you to reload, which is the most vulnerable moment and they can easily overwhelm the team if you hesitate.

Recommended Weapons:
 * Any Machine Gun
 * Any Assault Rifle

Demolitionist (Anti-Tank Unit) - Demolitionists are a cross between Support and Heavy Infantry. They are in charge of wiping out large hordes that have accumulated in-or-outside. If the Infected gather in one large crowd, multiple rockets and grenades may be the answer to wipe them out. These units can help the team if waves of Infected overtake the house, or if the Infected regroup into a large mob. However, Demolitionists can also be very vulnerable. Drawbacks include having a slow reload time, and creating splash damage (since it is a small map). If not properly timed, a wrong move might cost you your life.

Note that: despite the massive amounts of power dealt, Infected are much more resilient to explosives. Unlike in Quarantine, they will do much less damage to ANY Infected. Recommend Weapons:
 * Advanced Backpack with LAW and RPG-7
 * A Machine Gun (1)
 * M69HE Frag or M67 Frag Pack

Walkthrough
This is a basic walkthrough that can be used on any difficulty. However, as rounds progress and things get harder, some tactics must be changed to suit the situation.

Pre-game: The best weapons would be anything with a lot of ammo. It is suggested you bring 1 Assault Rifle and 2 Machine Guns. You should start each round by using the assault rifle; aim for the head to get faster kills. When the assault rifle runs out of ammo, switch to a machine gun. On the later rounds, the machine guns will usually be your primary artillery. Try to get familiar with your teammates as communication is the key to winning. The best servers to play this on are either Alpha, or the Black Market. Specialists are well known for their superority over the other players and should be used in Cabin Fever as much as possible. Make sure you have 8 players before proceding, and emphasize the importance of not leaving in the middle of the game.

Formation: There are three main areas to defend, the front and back doors, plus the hole in the wall. Keep 2 players at a door, and the rest to an assigned window. If support is lacking at one point; go and assist if you think your partner can handle it. Don't just camp or run around and do nothing.

Levels 1-4: These levels are the simplest; you can relax for a bit but stay on guard. Pick off the stray Infected as opposed to the main force.

Levels 5-10: These levels are slightly harder. The Witch will start appearing on Round 5. All attention should be focused on killing the tougher Infected first. At this point, all stations should be properly manned. At the end of level 10, everyone huddle around the basement door. STAY AWAY from it all all costs.

Levels 11-15: These levels are much harder; The Infected should not be trifled with this time around. Everyone will fully heal, right before the basement area is unlocked. The Enforcers will start appearing on Round 11. Everyone should maintain their posts and keep on maximum guard. NO ONE should abandon their post and run off. Consider the basement off-limits and stick to the posts. If you are overrun, regroup and rush around the Infected. The power will also go out frequently, Be sure to have someone go and turn it back on, so the game can proceed. As a last resort, an L96A1 Black Magnum will spawn in the basement crate. This weapon can come extreme handy if you manage to reach it and have not been killed. Though make sure you will survive. Surviving is more important then grabbing this weapon. On Round 13, a M32 Grenade Launcher will spawn. Both weapons can be extremely useful, if used properly. If there seems to be no hope, then you are screwed. As of the 2-3-10 patch, Nexon has put an invisible barrier to the pipes.

Levels 16-18: At this point, all Hell has broken loose. The remaining survivors should focus on evading the Infected at all costs. There will be horde after horde of Infected coming from all sides. Though no new Infected spawn at this point, the Infected will start coming from upstairs. As with the basement's early arrival, consider the upstairs OFF-LIMITS. Maintain all doors and make sure no one is split up. There will be many casualties during these rounds, but its best to stay focused. Many Enforcers tend to spawn upstairs, so stay down. On level 17, a Golden Punisher will spawn upstairs, but it is recommended that you don't pick it up. With low damage, slow reload rates, and being incredibly risky to retrieve, it is not a weapon to be using at this point. Only use it for emergencies; in case you are starting to get overwhelmed, and have low/no ammo. Then, on Round 18, the Airstrike Designator - LGB will spawn. If used properly, this weapon is vital at this point; get a good marksman to use it on mobs spawning outside.

Levels 19-20: Judgement Hour. At this point, everything may seem pointless. Keep in mind, there are only two more rounds until Evac finally arrives. Everyone will be weary and tired (if there IS anyone left), and considerably weakened. Only once every hundred matches does anyone survive at this point, but if you have; keep on fighting. Survivors should hang in there and stick in groups, because if you split up, there is a very small chance you will survive. The plus side? With the final Round comes the final weapon: The Minigun. This is by far one of the most useful weapons that will ever spawn and should definitely be picked up, if given the chance. However, don't make picking up ther weapon your main priority. Being selfish will cost your your life, not to mention the rest of your team. Also, if you DO pick up the Minigun, make sure you know what you're doing. Don't waste the gun by picking it up, and then panicking. Use it on the bigger mobs and stay clear from it if you don't think you can handle it. In addition, don't keep the gun firing too long---this will waste ammo, not to mention making it far less effective then it can be. Hold out for as long as you can, and hope that evac arrives in time.

Strategies
In the basement, to the right of the supply crate, there is a barrel and a bunch of pipes. It is possible to jump in the middle of the pipes (in between), and not be reached by the Infected. Be warned, the Enforcers has been known reach there from time to time, and it may not always work. Be wary of explosive Infected that crowd too close; their effects can still reach you. Bring a LOT of weapons there (2-3 MGs), or something with a lot of ammo. Also, bring a melee weapon with a long range (the Kukri or longer is recommended), because you will almost always run of out ammo on later rounds. From there, you can pick off the Infected with your melee.

Also, after round 16, there are some hiding places where the Infected cannot reach. Players can go there if their health is low, or the team has lost too many in order to keep their positions.

These areas include:

The Bathroom's door: Some people have managed to survive last rounds on it.

Window on the wall: Most effective place for killing several Infected when they are upstairs.

Note that these places may have been recently patched.

Trivia

 * There are new forms of the Infected, as opposed to just normaly Infected Mercenaries. They include the Maulers, the Chargers, the Witches, and The Enforcer.
 * The variety of Infected types in Cabin Fever, as well as its gameplay method is similar to the game Left 4 Dead . The mission itself is very similar to a Finale from L4D.
 * Some of the infected will lag, causing them to walk on the same spot. This makes them easy targets.
 * The Infected will gather into a mass and leave the house once the mission is failed.
 * The Enforcer is the hardest Infected to kill. Team up and aim for the head. Stay away from its after-effect.
 * The Witch and the Enforcer cannot be killed with just 1 shot; no matter what gun and where they are shot.
 * The Supply cases in the Cabin are similar to the random weapons chest in Call of Duty: World at War's Nazi Zombie  mode.
 * As the helicopter is probably run over with Infected, it may crash elsewhere, spreading the Infection.
 * On the 16th level, when the fence is broken, one Infected can be seen falling down the stairs.
 * Very few players have actually beaten Extreme mode legitly. Many players prefer OPKers do deal with all of the zombies to quickly get to the finish of Extreme mode.
 * When recovering the game states if ammo or health or both is replenished.
