Starbound developer Chucklefish began sending out beta keys for the PC, Mac and Linux game today. Those who backed the space-faring exploration game should see a Steam key in their inboxes momentarily, and the developer says a direct download version of the game will be available "as soon as we are able to efficiently provide it."

The Terraria-like game's official site reveals that over $2.6 million was raised by 124,176 backers in the developer's ongoing crowdfunding efforts. Starbound features procedurally-generated worlds in which players must gather supplies to take on quests. The "story in a sandbox" game received a new trailer to commemorate the launch of its beta version, which features some of its side-scrolling action.
