WAhahahahaha i've got the game last thursday (360) and i finished it on sunday.. This game is fucking beautiful. Story was kinda disturbing (i hate the black haired scary little girl). Althhough i liked the whole rewriting of your dna-code... In the end i never used my powers (only shock to dissable turrets) the guns were enough..

EDIT: finished the game with 800 achievement points btw WOOOT...
