Supply crates labeled MYST-G were designated to hold various rare weapons. This supply crate is guaranteed to contain one rare weapon for a variable usage time.

The Supply Crate MYST-G is the GP counterpart of the Supply Crate MYST-N.


It was one of the first to be released out of Combat Arms' new supply case system, which formerly organized each case by weapon and family category (ex. Pistol, P90-N). 

The MYST-G costs 4,000 GP per case, but contains ONLY rare items. Previously, common weapons---such as the G36E for a G36-N case---were part of the reward pool in a typical case.

On the other hand, there is now no separation of weapon types. Every single GP Rare primary weapon (ARs, SRs, SMGs) is an available reward. Nexon also claims that this case has a higher probability of rewarding a high-duration item.

As none of the other individual cases are available anymore, this crate is the only way to obtain a GP Rare weapon without reaching its required rank. Weapons obtained from this crate will have a duration of either 1, 7, 30, or 90 days. 

Unlike the MYST-N, which sends whatever you receive into your Inbox, the MYST-G automatically activates what you receive and places it into your inventory.
