The Angry Birds foray into the atmosphere has now made its way to Steam. Angry Birds Space is now available for the service, with a handy launch discount to boot. It's 20 percent off, making it $3.99 instead of $4.99.
The discount on Steam lasts through March 14. The price is a little more than its mobile counterparts, but the game received a generally positive reception on those platforms. Some of the same floating and power concepts were used in Rovio's follow-up, Angry Birds Star Wars.
