Below is a list of all weapons that are available to the player in the 2013 video game Aliens: Colonial Marines. Weapons in the game are predominantly divided into three main categories — standard weapons, heavy weapons and Legendary Weapons — plus several other miscellaneous items including hand grenades and sentry guns. Several weapons in the game were initially exclusives only available to players who pre-ordered or purchased a special edition release from a specific retailer, although these bonus weapons were later released as DLC for anyone to download.
