Mostly fine if basic.
Campaign only let's you play two of the available characters and playing in versus after that, isn't really worth it.
Difficulty level is very inconsistent.
Targeting system is far from perfect. Once game decides on a character to follow, it's really difficult to do any action in different direction.
Levels where you only fight Covers are really boring.
Final level relies a lot on rock-papers-scissors mechanics, which is basically luck.
