Crystal Defenders R2 launches today in Europe, after a relatively successful launch in North America a few days previously. The game is now available worldwide for download via Nintendo's WiiWare service, on the Nintendo Wii.

Featuring a list of jobs and locations from Final Fantasy Tactics A2: Grimoire of the Rift, Crystal Defenders R2 requires a lot more strategy, as players need to defend their crystals from the oncoming horde of enemies.

The game is set to feature a worldwide ranking system, so you can see how you're performing against your friends, as well as a host of other features which Square Enix claimed will only increase the excitement and replayability.
