I quite like that we can apparently complete the game both with killing people and without. And I'm also feeling the love for the Rob Cobb icons.
And yeah, like Hicks said, they never said there'd be no weapons. They just said they'd be f*ck all use against the Alien.
EDIT: I'm also noticing "Collected 100 archive logs". That's a lotta logs. They better have some interesting info on them.
