Fullbright's adventure game Tacoma is free for a limited time through the Humble Store. The game normally costs 16.99 euro but for the next 72 hours you can get it for free.
To get the game, just go to the Tacoma page on the Humble Store, and click "Get the Game". Once you get the game, it will be yours forever. The offer ends on Sunday, March 24 at 10 a.m. PT. This time you get a DRM-free copy of the game.
