Last Keep is a fast-paced endless tower defense game where every wave pushes your build further. Choose from four distinct heroes, place damage and support towers, and shape every run with skills, equipment, and high-rarity drops. Boss waves hit hard, and smart positioning matters just as much as raw power. When the line is about to fall, use Diamonds to revive and fight for one more record-breaking run. Diamonds are consumable in-game currency available through in-app purchase, and each revive costs 1 Diamond. Features: • Endless tower defense runs with escalating enemy waves • Four unique heroes with different combat styles • Skills, equipment, and rarity upgrades that change every run • Boss battles, fast decision-making, and high-score pressure • Diamonds can be used to revive during gameplay, with 1 Diamond consumed per revive • Leaderboards to track your best runs and compete for higher scores Build, survive, revive, and see how long you can hold the line in Last Keep.
