Gridlock
Released
Build a maze of deadly defenses. Research, upgrade, and survive endless waves in this sci-fi tower defense
Your defenses are the maze.
Combine eight defense types, from dependable Lancers and explosive Howlers to chain-lightning Arcs and piercing Railguns. Slow enemies with Stasis, support nearby defenses with Beacons, and build combinations that do more together.
Upgrade your favorites through multiple tiers, choose specializations, and push them further with Elite refits and Overclocking. A longer maze buys time. The right weapons
make that time count.
Research your next advantage
Spend credits on the battlefield and Data on research. Unlock new defense families, stronger upgrades, and improvements to your economy and core.
On Frontier, research also opens up board expansions. More room means more possibilities.
Six battlefields. Four ways to play.
Choose from Frontier, Citadel, Crossfire, Long-haul, Rift, and Trident. Adapt your designs to different layouts and defend against attacks from one, two, or three entrances.
