Did a search but didn't find anything on this. Anyone planning on picking this up via Steam in 2 days? Apparently, it's a free title from the Source SDK that allows for 4-player online co-op. It actually looks really fun for what appears to be a top-down shooter of sorts.
If anyone wants to get some games in, send me a Steam FR @ TheDeanPSU.
Here is a screenshot and a link to the title: http://store.steampowered.com/app/630/
