In case anyone else is curious, here is the description (one click away from the main page):
> LOVE is a cooperative online first person adventiure game. You play as a scavanger on a small planet who together with other scvangers will build a settlement by placeing a Monolith some where in the world. This Monolith makes the ground lose so that you can shape the environment around it in to what ever you want. Build walls, catacoms, houses and shape your settlement any way you want.
