Hidden Path Entertainment's tower defense sequel Defense Grid 2 is primed for a September release on Steam, Xbox Live, and the PlayStation Network, publisher 505 Games announced this week.

The result of a successful Kickstarter project and follow-up investment, Defense Grid 2 boasts a lengthy single-player campaign along with online PVP and multiplayer co-op modes. The sequel includes new tower types, new playable environments, and a level-creation toolkit that allows players to share their custom maps via Steam Workshop.

Defense Grid 2 is up for pre-order on Steam at a 10-percent discount ahead of its launch on September 23. Pre-release buyers receive an advance beta copy of the game for Windows along with additional rewards that unlock as more players join the beta. Pre-order incentives include giftable copies of predecessor game Defense Grid: The Awakening, digital art books, and an original audio-only storyline, among other bonuses.
