Spiral Knights

Sega released a free online hack and slash today, Sprial Knights. It's very multiplayer based. The only part that seems to be solo is the tutorial. You can start your own party or crash another like I did. Your character has a limited amount of energy, which equates to play time. If you run out, then you have to wait a day to play again or buy more energy. Energy is also used in alchemy to create new items.

So take a look. If you ever wanted to play the spawn of Little Big Planet and Diablo, then this is the game for you. Works on Windows, Mac, and even Linux.
