Riftguard

Riftguard is a complete tower defense campaign across five original realms — sunlit meadows, ember canyons, a neon city that never sleeps, frozen wastes, and the Void Fortress at the edge of reality. Riftspawn pour through the gates, and only your towers stand between them and the crystal heart.

Build from 20 hand-crafted towers, each with its own art, attack style and personality — long-range arbalests, chaining storm coils, frost spires, gravity wells, drone rookeries, blocking warcamps and more. Every tower offers three upgrade paths that visibly transform it on the battlefield: Power, Control, and a Specialization that's unique to that tower. Commit to a final tier and the other paths lock — every defense is a build you'll want to replay.

Enemies that demand answers, not just firepower. Armored shells, decay-proof shields, regenerating blooms, splitters, stealth phantoms, swarms, and flying drakes that skip your ground game entirely — each countered by different tower combinations. Five ability-driven bosses summon, teleport, disable your towers and split apart when they fall. Four difficulties from a gentle 15-wave tutorial to a brutal 50-wave nightmare, 12 challenges, cosmetic tower skins, titles, and persistent progression across sessions.
