This section contains the general information that is useful for both teams:

Gamemodes and Maps

Infestation The infestation gamemode is Aliens vs Marines, this gamemode ends upon the eradication of one side. Custom events started by admins can sometimes take place during this mode.This is the default gamemode of CM. Typically however the Server and Hub will show the Map Name as the game mode instead of Infestation.
Hunter Games The Hunter Games gamemode is split into two modes, the first one being a deathmatch style with random weapons, mostly melee or thrown, scattered about, typically with admins spicing it up. The second mode is where there are still weapons scattered about and it is still a free for all deathmatch however RP is encouraged due to how multiple 'Tribes' are spawned in at certain areas of the designated map to play on. From there the tribes can go to war, conduct diplomacy, execute their prisoners of war, go looting, etc. Nearing round end the remaining players of the tribes are told to get to more of a 'There can be Only One' styled of gameplay, with the last player standing wins. This is a gamemode that needs one of the heads of staff to be online in order to play this mode properly. Remember, this is a gamemode that can only be playable from round start.
Whiskey Outpost During the Whiskey Outpost gamemode you play as one of the Marines in the USCM battalion 'Dust Raiders' who were previously in charge of 'keeping the peace' in the Tychon Rift sector. The aim of the mode is for the Dust Raiders to hold the outpost for as long as possible (Until Wave 10) against the xenomorph hordes, the game ends if either the aliens annihilated the Dust Raider marines or the Dust Raiders survived 10 waves against the xenomorphs. Requires one of the heads of staff to be online in order to play. Take note that after the round starts, you cannot late join onto the marine side and as such are forced to observe or play as a xeno.
Extended The Extended gamemode does appear in CM, but it's reserved for admin events only. Normally xenomorphs aren't spawned in extended rounds, however it's up to the admin hosting the event. An example event that uses extended would be the CLF vs USCM.
Maps Colonial Marines has 5 maps. The foggy, tropical warzone colony of Lazarus Landing on Planet LV-624. The harsh, cold winter environment of Ice Colony on Planet LV-343 'Ifrit', also known as Shiva's Snowball. The modern, hot areas of the research facility Solaris Ridge on the Planet 'Big-Red'. The everfloating, maximum security station is known as the Florina Orbital Penitentiary or simply, Prison Station. And the soon-to-be overrun Whiskey Outpost in the Tychon Rift sector.
