Dude, this is one of the greatest.
I am honestly telling you this. This is probably one of my favorite zombie games that I have ever played. I like how you got so detailed where you had each of your team members work at something (one guy with the elevator, and the other with the barracading bed). This really reminds me of a Resident Evil game, and that's a good thing.
Well, I can't wait to play the sequel, if you'll ever get around to finishing it lol. But keep up the good work. I love this game!
Over all, I'm giving it a 9/10. ^^
