Notorious Games needs your help to bring its Xsyon sandbox MMO to a wider audience. The title has a new Greenlight page on Valve's Steam digital download service and the post-apocalyptic survival MMO is seeking enough "yes" votes from the community to make it available to Steam's 40 million-plus users.
Xsyon is "an entirely player driven online game with a living and changing environment." Gameplay involves the formation of tribes, the shaping of landscapes, and the construction of towns, not to mention variations on typical MMO questing, gathering, and hunting.
