Rat King Entertainment recently launched its Steam Greenlight page for 3D puzzle-platformer Tri. The game, a first-person platformer in the same vein as Antichamber, has players exploring towers and dungeons, building platforms and solving puzzles along the way.

Tri's alpha version, composed of 12 levels, is available now through the Humble Store, Desura and Indie Game Stand for $10. Buying the PC, Mac and Linux game now amounts to a pre-order, as players will receive an upgrade to the full version of Tri when it launches somewhere between Q4 2013 and Q1 2014.
