Tidewall

The sea is rising and the raiders are coming. Build a wall of brick, iron, and grit — and hold the line.

Tidewall is a coastal tower defense game with the soul of a castle defense classic. Stack walls, raise towers, post guards, launch boats and planes, and dig factories beneath the sand — then watch it all tested by the tide and everything that rides in on it. It is part base builder, part real-time strategy, and entirely about holding one stretch of coast.

DEFEND YOUR COAST
• Place walls, towers, and guards in a living side-view world
• Command naval units and aircraft; build underground factories for the long game
• The waves hit harder every time — raiders dig, barricade, and chase

MANY WAYS TO PLAY
• Campaign — climb the levels and break through the boss fights
• Invasion & Aid Allies — push the offensive and survive the carrier boss
• Survival & Endless — one coast, no finish line, how long can you last?
• Chase — fast, taunting raiders that never let up
• Versus — duel the Commander offline, or send a link and battle a friend live
