Pretty good, very easy, story is a little eh....
The game took about 10 hours maybe slightly more to beat the entire thing, and it was pretty easy to play. I died a hell of a lot more in the first one and this one was much much much easier! Even on Normal difficulty it was ridiculously easy to beat the game.
Graphics deserve a 10+, absolutely stunning areas and players, well done and thought out! Sound effects were awesome and the weaponry to match the atmosphere was great!
Some of the levels were eh.... Like being inside the giant worm, that was a really cool place to play but obviously not very realistic in any way, but still fun to play. I know it's a videogame and the levels are all supposed to be crazy and futuristic, but being inside of a giant worm was a bit too far stretched. The snow level of driving the big wheeler was a lot of fun except for crossing the iced lakes.
Enemies were fun, bosses were fun, nothing was too hard or insane to have to get through, it was pretty easy the whole time.
I would recommend this to anyone who loves the first game and wants more! It is definately worth your time and your money, get this game and enjoy it!
