Aspyr and Hidden Path are announcing on Monday that Defense Grid: The Awakening is coming to retail later this year. Defense Grid was released late last year through digital distribution and garnered critical acclaim (including an 8.0 from IGN). Under this new agreement, Aspyr will have worldwide retail publishing and distribution for the game.

Defense Grid features 20 story levels and numerous challenge modes. It's an advanced version of the popular tower defense genre that is found online, with the goal of defending an area from waves of oncoming enemies. The game has plenty of options, with 10 tower types, many of which can be upgraded, and a slew of opponents that escalate in difficulty.

The game is scheduled to come out this summer.
