Call of Duty with Aliens.

There are only a few elements needed to complete this entirely:


 * Pulse Rifles with Explosive Ammunition and Ammo Counters


 * SmartGuns (they already have these, Sentry Guns)


 * Flamethrowers


 * Dropships


 * Aliens with Acid Blood and little fuckers that choke you and implant an embryo, before the embryo bursts out of the chest later


 * the one marine with a pump-action that says "I like to keep this, for close encounters"


 * Sigourney Weaver

Other than that, Infinity Ward has it made.
