The Humble Frozen Synapse Bundle has generated more than $1.1 million in sales.
The bundle included the indie hit Frozen Synapse and puzzle game Space Chem, with the "unique photographic experience" Trauma added for free.
In total, 231,799 bundles were sold, with buyers paying what they saw as a fair amount. The average paid for each bundle was $4.81 each; Windows users paid an average of $4.13 each, Mac users paid $6.96, and Linux users paid $9.41.
Any buyer who paid above the total average also received the Humble FrozenByte Bundle, which included Trine, Shadowgrounds, Shadowgrounds: Survivor, Splot and Jack Claw.
The third Humble Indie Bundle, which closed in August, was the most successful in the history of the initiative, generating $2.16 million from 372,364 sales.
