My game froze all the zombies at the end of wave twenty, so whenever I shoot, the zombies skin flies off, but they've stopped moving, the screen moves with me, and the waves just stopped. I can now repair my car in relative peace, but with no need to buy guns. Interesting glitch that needs to be fixed. Took the fun out of the game.
This is an amazing game, and it really does seem as if you are inside the story. I loved everything about it, the music, the history, the characters, the details, everything!
