This game is not great. It's got an arcade-y scoring system but a campaign that isn't that fun to replay. The multiplayer does more with the scoring idea, but was very buggy and empty. When the multiplayer did work, the optimal way to play was very "let player 1 kick them up/slide into them and player 2 blasts them into an environmental hazard."

However, filling out the checklist of every single way you could score a kill is so interesting. The game rewarded curiosity. "Hrm, maybe i'll attach a sticky grenade to this dude, kick him away, do a ground slam with my electro whip, and detonate the explosive while he's up there." "hrm, maybe I'll slide into a guy and shotgun blast him to send him flying into a spike wall." Every time a new finisher name popped-up, you felt smart!
It is certainly a unique shooter with quirky environmental sandbox design that I'll never forget.
