Defense Grid 2, DG2, is the highly-anticipated sequel to Hidden Path Entertainment’s 2008 Defense Grid: The Awakening. Setting the bar as the definitive tower defense game, Defense Grid 2 introduces new worlds and threats to test your tower placement strategies. With a bold new look, a compelling single-player campaign, and the addition of new game modes, online player-versus-player and multiplayer co-op, every play-through brings fun new opportunities and challenges.
DG2 comes with a story campaign featuring 21 stunning maps, dynamic level movement, an expanded story and cast of characters, hundreds of challenge mode experiences, new multiplayer modes, a procedurally driven audio score and the ability for players to build their own levels. DG2 also introduces players to DG Architect, a level creation tool set connected to Steam Workshop where players can create their own unique levels to share and possibly even sell if selected.
Its Gamers Gate, not steam.
