The Humble Frozen Synapse Bundle already received a surprise bonus with point-and-click adventure Trauma, and now indie puzzle game SpaceChem has further sweetened the pot. In case you are not going through enough mental contortions from trying to plot your next move in Frozen Synapse, you can take a break by trying to solve problems with SpaceChem's molecular machines.
You can buy the bundle here (opens in new tab) . If you already have it, you will find that SpaceChem has been added to your account. Buyers who pay more than the average also receive Trine, the Shadowgrounds games, the prototype for Jack Claw, and a preorder for Splot. One week remains for this sale, which benefits the Electronic Frontiers Foundation and Child's Play.
