Bundle Stars Build a Free Bundle Week 3

PC Gamer and Bundle Stars are still working together to bring literally millions of Steam keys to our hands. This week it's the shoot 'em up Really Big Sky. But you must have a Twitter account to get your copy. You need to follow PC Gamer and Bundle Stars as part of the offer widget.

In Really Big Sky, you control a small ship in a big universe. A twin-stick shooter, you control the craft with one stick and fire in various directions with the other - or keyboard to move and mouse to fire if you haven't got a controller. It is procedurally generated, meaning it adapts to your play style, with gas giants and planets to blast through, plus events such as black holes. Compete on the leaderboards across twelve different game modes including Arcade, Nightmare and Boss Rush.

Just go here and get your key - so long as you have a Twitter account. And while you're on Twitter, follow GameGrin and never miss a news story!
