This is a bunch of games I played on Tetris Battles new game mode called arena. It features a real live 6p game mode with chat and a spectator mode.
The main difference from this mode to the Tetris friends arena is the KO system, originally this was desigend for player vs replay systems so that it would not be too easy to win vs the replay. But now it is featured in real live gameplay. This will be interesting since strategies like 4 wide will most likley not be as strong and strategies like ST stacking will be much better as you can survive much longer.
More stuff comming, just wanted to throw some games out there.
