developer RuneStorm recently held a 10-day, internal game jam. They were so impressed (and amused) with the results they've elected to share it with an audience.
The game, Viscera Cleanup Detail
, is a first-person "space-station janitor simulator," a sort of parodic take on the kinds of messes left by other sci-fi games' action heroes. Built with the Unreal SDK, the game is currently in alpha and a little rough around the edges, but charming (and gross) all the same.
Internal game jams are picking up as team-building and creativity exercises for developers, and it's interesting to see the products of these internal jams released as concepts or even prospective commercial products.
