SpaceChem joins the Humble Bundle

Once again, the Frozen Synapse Humble Bundle continues to grow. As if the addition of Trauma wasn't enough, all purchases will now include the indie game SpaceChem by Zachtronics Industries. According to the developer, it's "an obscenely addictive, design-based puzzle game about building machines and fighting monsters in the name of science."

The game normally retails for $14.99 on Steam, but through the bundle, you'll be able to pay whatever you wish.

As of writing, the Frozen Synapse bundle has been picked up over 150,000 times, with an average purchase price of $4.67. The deal ends in one week.
