mpr++ is progressing nicely, and by now performing much better than the old 0.2.5a version that went public Christmas 2011 as an early sneak preview
The Demo version is available in 1024 x 768 and 800 x 600 resolution for Vanilla, Balance of power, Error correction mod, Fluid Multi player mod and Ultimate Dominion mod.
Some of the new features are all new ogre models for all ships, new phaser and torpedo effects.
