It's nothing breakthrough, but it's fun to break and explode things and buildings.
The only gripe I have is the targetting system. It's very finicky, if you don't get it exactly right, you will miss your target.
The sledgehammer is also finicky, even if the grunt is in front of you, with its quirky lurch when using the sledgehammer, it's easy to miss your target.
Another improvement is the variety of weapon, even though it is quite varied as it is, it can do with one or two more kinds.
Another gripe that I have is that I cannot be a gunner if I have another person to drive the car (like after rescuing a hostage), unlike in Halo where you can choose to be a driver or a gunner.
The game is stable, not a single crash from start to finish.
All in all, pretty entertaining for two weeks.
