You know what's really fun? waking up after a few years of be unconscience, and finding that everything you knew had changed. Which is exactly what happens to your created protagonist who, this time around, actually has a voice, and you have the choice of being male or female (or be a male who wears female clothes).
Well, as much fun as that really is, taking back the city, block by block, is even more fun. This time around there's is a lot more **** that you can do. Not only is the stuff fun to do, but, you also get rewards for doing almost every extra mission in the game. For example, you can play a game within this game where you take on wave after wave of zombies, (yea, I know, FUN!), anyway, after you beat all the waves, you get a zombie mask.
So pick up this game and don't put it down until you unlock EVERYTHING!
(And the is a lot
of replay value)
