The Red Army took longer than expected to mobilize but now it's ready for war. Starting today, Stalin vs. Martians can be purchased digitally worldwide.

SvM was originally going to be available on the much more appropriate release date of 4/20 but was delayed at the last minute. You can purchase the game through GamersGate, Impulse, and Direct2Drive. It should be added to Steam later today.

In the game's 12 mission single-player campaign, players must fend off a Martian invasion of Siberia. It carries the proletariat-friendly price of $19.95 so don't expect a massive game. Still, could be an entertaining diversion for a few days.
