Last Beacon is an atmospheric isometric tower-defense game set on the final inhabited island. Build Sentinels, Mortars, Frost towers, and Relays across the coast, then connect every defense to the lighthouse power grid. Limited parts and grid capacity make every placement matter. Upgrade your defenses, trigger Beacon Overdrive at the right moment, and adapt to increasingly dangerous mechanical creatures. Hold the line through ten waves and defeat the Abyssal Colossus to keep the last light alive.
