Did some multiplayer versus and it was a lot of fun. The controls feel tighter than the original and the use of B for multiple actions is not a problem. There's some little nods to other games like custom tags ("Street Fighter," "BSAA," "I've covered wars you know," etc.) and character parts (Servbot head, Frank West backpack) available too. You can choose from five character factions (Rounders, Fight Junkies, Snow Pirate Elites, NEVEC Black Ops, and Femme Fatales) and customize their looks, emotes, abilities, weapon types, and tags by unlocking stuff and leveling up.
I have a feeling that the game's major problems are in its campaign mode, but that's not why I bought it. I loved LP1's multiplayer versus.
