Figure I'll revive this because I just saw it... that said on with the semi rant
ok this is the only part I should put out of spoiler for now... DON'T SEE THIS IF YOU WANTED SOMTHING THAT REMOTLY FOLLOWING THE GAME!
For those of you who liked the style of horror in the game you'll love the movie. They also have a neat little teleporter. not the giant earmuffs from Doom3, but it's a room, when activated theres a clear sphere in the middle that grabs you and literally chucks you to the destination point. They toss in a joke about failures in the system before UAC perfected it...
