Injustice: Gods Among Us, at E3 this year. Dubbed the clash system, this special function combines individualized cutscene cinematics with a process of betting your character's super meter, with the fighter betting the most winning the wager and getting the special move. It sounded confusing at E3, and it still is now at Gamescom, which is why NetherRealm is considering removing it from Injustice entirely.
"I can see the cinematic moves staying and the wager system going," NetherRealm's Adam Urbano tells Joystiq at Gamescom. NetherRealm is tweaking the clash system and may end up disposing of it entirely, while keeping the character-specific attacks and cinematics, Urbano says.
