I agree entirely, the ending was awful. I was all ready for a final fight with Alma or with the guy she was controlling and instead got a cut scene with Alma *erm* taking avantage of me. Which, if you're keeping score, means that in the first one you were her son pulled from her prematurely going after your brother and in the second you were kinda competeing with the other dude to be her new baby daddy. I wonder if in the third you'll play the child created from 2 who goes back in time and become his own grandfather.
I hope in 3 they go back to the style of having everything in close quarters where it's scary/creepy and not open areas like in COD/Halo/GoW/etc
He's dead, Jim.
