Your turrets fire themselves. Every decision that matters is yours. Swarmfall is a roguelike tower defense on the last living world. Turrets on the planet's rim find their own targets: you never aim and never tap an enemy. You choose what to build, what to fuse, and when to walk away with the haul, while the swarm closes in. LEVEL UP, CHOOSE ONE Kills feed experience. Every level deals a hand of cards and you take one: a new turret, an upgrade, or a synergy that rewires the whole build. Deep Roots doubles the damage to anything near the planet and triples it on anything latched on. Living Mantle regrows the ground under you. NINE GUNS ON THE RIM The Reef Lance locks one target and ramps to 2.6x the longer it holds. The Ember Spitter lobs shells that detonate and leave survivors burning. The Tide Coil chains arc bolts through anything that clusters. The Spore Launcher sends homing seekers that pick their own victims. The Shard Battery shreds at point blank and nowhere else. The Blight Garden plants a rot that leaps to whoever stood nearby when its host dies. The Tide Anchor rings like a struck bell and slows everything its wave passes through. The Rime Lattice stacks cold until a body hard freezes, and a heavy hit shatters it into everything around it. The Undertow Maw opens a gravity well on the thickest pack, drags it into one knot, and crushes it. TWENTY-TWO EVOLUTIONS Raise a turret to level 2 with the right partner mounted and the two fuse. Reef Lance and Ember Spitter become the SOLAR LANCE, a beam that sets its victims on fire. Ember Spitter and Spore Launcher become the BROODFIRE MORTAR, shells that release seeker drones on impact. Tide Anchor and Undertow Maw become the MAELSTROM, rings that drag the swarm instead of slowing it. BANK IT, OR PUSH Every credit you earn in a dive is at risk until you get it out. Extract from the pause menu whenever you choose and you bank all of it. Die down there and the deep keeps half. Kill a monarch and it pays a bounty and knits 30% of your planet back together, and the next wave is already coming. A SWARM THAT CLOSES IN Thirteen creatures, from cinder mites up to the Deep Mother herself, drawn in bioluminescent deep-water dark. Elites rise wearing afflictions: Veiled, Frenzied, Gorged, Budding, Weeping, and the first of each in a dive is called out the moment it surfaces. Everything resists one damage family and folds to another, and the briefing shows which for everything you have already killed. The swarm reveals itself a species at a time and comes at you from wider angles as the dive goes on: one front, then an arc, then a pincer, then a full ring. THE DESCENT Eight depths each add one permanent modifier as you unlock them. Elites rise more often. The mantle holds less life. The swarm moves faster. Monarchs rise in pairs. Elites carry two afflictions at once. The swarm's numbers swell by 30%. How deep you can still hold is the real score. EVERY DIVE COUNTS Banked credits buy permanent upgrades in Research. Turrets unlock by playing, through lifetime kills and your longest dive, never through purchases. Daily directives pay out for specific work: burn down 150 fire-family creatures, hold the line to 6:00, slay a Deep Mother. Records keep your season. The bestiary fills in as you meet what is down there. NOTHING BETWEEN YOU AND THE GAME No ads. No energy timers. No login. Plays offline. Your save follows your Apple ID through iCloud, so a new iPhone or a reinstall picks up where you left off. The one thing for sale is the Commander's Commission, an optional subscription: 2× speed and dives by seed, and nothing that touches a run. Swarmfall collects nothing about you. Under a quarter mantle, every gun on the rim opens up at once. Last Stand is not something you buy. It is the world screaming.

One Tower: Idle Tower Defense is an idle tower defense game with a single rule: you never build a second tower. One tower stands between the core and an endless alien invasion, and every run is a chance to upgrade it, survive longer, and turn defeat into permanent power. Combat fires automatically. You spend the cash each wave earns on attack, defense, and utility upgrades, decide when to trigger your special weapons, and push your tower as far as it can go. When it falls, you keep the coins, return to the workshop, and come back stronger. It is incremental tower defense: short runs, big numbers, and progress that never resets. ONE TOWER, ENDLESS WAVES • Defend a single tower against endless waves of aliens, elites, and bosses • Upgrade damage, attack speed, range, critical chance, health, regeneration, and more during every run • Layer overlapping defense fields, shields, and mines around your tower • Push through harder tiers and chase a new best wave every time IDLE PROGRESS BETWEEN RUNS • Invest coins in permanent Workshop upgrades that carry into every future run • Research in the Lab keeps progressing while you are away, so the tower grows even when you are not playing • Come back to rewards, finished research, and a stronger tower BUILD YOUR OWN TOWER DEFENSE STRATEGY • Collect and master Relics that reshape how your tower fights • Deploy support Drones that amplify damage, boost allies, and burn enemies • Forge and merge Augments for attack, defense, utility, and special power • Unlock Special Weapons such as nukes, barrages, and overdrive, and choose the right one for each wave • Every combination changes the run: a roguelike loop where the decisions are yours and the shooting is automatic COMPETE AND COLLECT • Enter tournaments and climb the standings against other tower defense players • Complete daily missions, milestones, and limited-time events for extra rewards • Track your best waves, total damage, and progression in your profile WHY ONE TOWER Most tower defense games are about placing more towers. One Tower is about going deeper with the one you have. No maps to memorize, no mazes to build: just your tower, an endless wave count, and the question of how far one tower can go. It is an idle defense game you can play in a few minutes on the bus or leave running while you work, and the workshop, research, and relics give it the depth of a full strategy game. MADE FOR IDLE TD FANS If you enjoy incremental games, idle games, or classic tower defense TD, One Tower gives you the best of both: the satisfying growth of an idle game and the wave-by-wave tension of tower defense. Runs are short, defeat is expected, and every defeat makes the next run better. How long can your one tower hold?
