I don't even like these kind of games
They scare the shit out of me and I hate feeling pressure in games (Don't judge). But I don't know, I am flat out Addicted (capital for epic) to this game. The plot is so realistic, and I love how you can build out the character through so many level up options, and how the plot get's thicker and darker as time goes by. It made a bit a sad, because you know that one day the couple (like that emotionally wrecked guy in the first safe house with his wife) won't make it in the end, it's quite depressing.
Keep it up, I'm loving this game. I do have to admit, when zombies randomly come out from the ceiling I shit bricks every time.
