I think you'll have to wait until Desura is released
There are two ways of getting the game:
* download game Data and Engine separately (see provided links) and try to launch them (this method didn't worked for me)
* alternatively, grab tha latest Engine version which already includes game Data by issuing "hg clone https://pywright.googlecode.com/hg/ pywright" command (you'll need 'mercurial' package to be installed)
They need lower price and bundle with Survivor for selling more units.
$10 for each, and announce once reach $10000 sales they put level editor document/tool online. :D
Or should release modding tool and level creation tool. --- although the sourcecode released already.
Network gameplay would be great though.
Game: Minetest Game
Similar to minecraft, but already GPL, free and with low system requirements.
I have tested it as well a few days ago.
As said by sixsixfive there isn't much for now.
All you can do is roam the map with 5 units and kill 5 enemy units that don't fight back.
I see, there was no such repository before and now.
Ok, I think we should wait then and not add it for now until the project becomes more mature.
