Xenogalaxies is a space voxel game - you build custom ships, travel, take missions, fight in space and on foot for the missions or for the loot.
There was prototype and trailer done with xna, what you see in the video was done in 10 days of custom code (2 guys at night after the day job) + small bits of space construction kit (unity store paid asset).
We got a funding running so I m not posting any links - but we will post dev log update here - because it’s now in Unity and Unity rocks!
