We felt that we have not created enough buzz around the release and there was not enough info about the game to make purchase decision.
So we have just created a free demo version of the game.
The demo will allow you to play up to 2 days and you won't be able to use tram/tube once you get to the Central control.
I think this will give the players enough playing time to check out the mood and playing mechanics of the game.
Steam demo for Subterrain is alive!
But if you would like a DRM free version here is the link !
Version 1.0.0.7
Enjoy! And spread the words!
