The ultimate nerd game
Don't get me wrong, I really enjoy DEAD SPACE - yet you can't escape the fact it's a mish-mash of many horror\sci-fi movies (and games too, for what matters). I have found these ones:
EVEN HORIZONS: people going to a deserted spaceship - plus many enviroments are clearly inspired by the design of the movie
THE THING: polymorphic entities.
LEVIATHAN: polymorphic mutants and people using futuristic mining tools to fight them
VIRUS: alien\monstruos force recombining body parts to create killing machines.
THE EVIL DEAD: recorded statements warning you the monsters have to be dismembered.
ALIEN\ALIENS: the mother of all modern sci-fi\horror stories - no need to comment.
HARDWARE: damaged automatic doors with a penchant for mutilation.
Anything more?
