Great news for the Foss enthusiasts: after many years of constant nagging the latest release of the great parcour/arena FPS Warsow has now most of it's artistic content under the Creative Commons Attribution Share Alike 4.0 license (with a few remaining but clearly marked ones under CC-by-ND).

Also updated particle effects in Warsow 2.0

You can find more screen-shots in the above link and the full changelog here.

Rendering speed was also increased (claimed to be 30-50% faster) and a movement tutorial is now included.

So far I always recommended Xonotic over Warsow as the coolest (=most competitive; Red Eclipse is also cool, but much more casual) open-source arena FPS, but I think I might reconsider this now...

Happy fragging :p
