Sliding Doors

Sliding Doors are workable objects in Combat Arms. Pressing E (default key) would open or close the door, allowing passage to what the door was blocking. They are currently only four sliding doors in the game, all in Snow Valley. It is humorously noted that if two people are attempting to open the door at the same time, it would keep on opening halfway and then closing, making it really frustrating. These doors can be used as surprise attacks if one is aware that someone is on the other side (though it can be also a coincidence).
