Grid Guardians: Tower Defense

Merge turrets, plan every move and stop the robot invasion in a turn-based tower defense with no timers. NEW: THE CAMPAIGN - 30 levels across three worlds: Boot Camp, Iron Wall and Overdrive - Boss fights on levels 10, 20 and 30 - New robots that change the plan: Runners charge two cells a turn, Shields block your fire, Medics repair their friends and Drifters switch lanes - Earn up to 3 stars on every level by building your biggest turret - Get 3 stars on every level of a world to open its Hard mode, with 2 more stars to earn on each level MERGE YOUR WAY UP Tap a turret and the board lights up: amber to place, green to merge, blue to swap. Merge two of the same level into something stronger and climb the ladder from gatlings to rockets to flamethrowers, all the way to 256. THINK, THEN MOVE Nothing is timed. A turn takes as long as you want. When you're ready, hit END TURN and watch your turrets open fire. BOOSTERS FOR TIGHT SPOTS Call down a Firestorm, Freeze the robots in their tracks or give every turret a Double Attack when the line is about to break. ENDLESS MODE Every turn you survive is a point.
