Mmm its ok.
An ok shooter that i wont remember in a few years. Like halo it is very aged as shown by games like UT3 ware games that have a non existing or verry shallow story just is boring.
Multiplayer os decent but here again it all seams so still evrything is the same no weapons stand out like innovating. The chainsaw under the was just added so would be allowed to have blood splatter over the screen. And its slow. I really cant say this enough FPS cant work good with a controller. Its just boring with a sight that is huge and with autoaim.
And again the story doesn't exist.
What ms have done well is the marketing, the same thing they did well with halo.
