In 2001, Bungie and Microsoft studios released Halo: Combat Evolved. Not only was it extremely well-received as an outstanding PC game, but it was also one of the main reasons behind the still-fledgling Xbox game system. It is still considered one of the most influential first-person-shooters of all time, and yet it has a staggering amount of influences of its own. Its pulp science fiction story borrows numerous elements from pre-existing novels, games and films, but one of the most recognizable influences is James Cameron’s 1986 film Aliens.
A follow-up to Ridley Scott’s classic space chiller Alien, Cameron’s film gave his installment a new, more action-driven dynamic, placing hundreds of the sharp-toothed, acid-bleeding creatures (as opposed to just one) against a strung out squad of space marines. In Halo, the player takes the role of a biologically augmented super-soldier known as Master Chief, who is the prime asset to the game’s own set of space marines. Not only is this militaristic aspect reminiscent of Aliens (even in the mechanical designs of the dropships and weapons), but Bungie also went so far as to include the character of Johnson, a loud-mouthed, African American drill sergeant who is almost exactly like character of Sgt. Apone in Aliens.
The parasitic nature of Halo‘s most terrifying enemy, the Flood, also reminds one of the nature of the xenomorphs in the Alien series. Although the Flood simply take over the body of the host they attack, they still start in a small, spore-like form and depend on other sentient species to survive and reproduce.
