It's not terrible. I bought it 2 days ago. If you liked the first Dead Island game you'll like this one. It's pretty much the same except with new weapons, new character, new zombies, new skills, different menu layout and a new map. And it's alot less buggy than the first one.
Not so much with me. I was a HUGE fan of the first Dead Island, and as soon as I threw this game in the ol' disc slot, I wanted to take it right out. The story is what has got me. ITS TERRIBLE. Doesn't help that there are a lot of glitches and bugs they should have caught right off the bat in testing stages, but I guess they decided not too.
