Not as good as Halo CE:
The vehicles were changed. the banshee (to me) was not as good as the one in the first halo. Also the ghost now had boosters, but you couldnt shot while they were on so it made it worst.
THe Cov. dropship was changed. thats a plus making it more powerful, same with the pelican adding a gun in the rear making it better than just sitting in a ship getting shot up.
The truck/jeep was better adding two different types of guns. one with a machine gun and one with a powerful turrent.
