Torus Keep–Space Tower Defense

Spin one ring of satellites to defend a lone space habitat. Torus Keep is a roguelike tower defense game you play with one finger: drag to aim, pick an upgrade between waves, and decide when to cash out.

No energy timers. No loot boxes. No premium currency. Everything that changes how you play can be earned by playing, and it plays offline.

SHORT RUNS, REAL DECISIONS
• Each sortie is seven stages ending in a boss. Between stages, choose your route: an elite stage for more salvage, a supply cache, a repair dock, or Recall to bank everything you carried.
• Pick one of three upgrades as you go: a new satellite, a power-up for one you have, or a boost for the whole ring.
• Breach, and you still keep 60% of your salvage. Clear a sector, and carry your whole build into the next one.

12 SATELLITES, EACH WITH A JOB
• Chain lightning through swarms, melt bosses with a beam that grows, root the fast ones, lay minefields as you spin, or store your spin in a Flywheel for one huge shot.
• Choose four per sortie and set each one's aim: Most urgent, Toughest or Fastest.
• At Mastery 10 every satellite earns a named signature Refinement: Hammer Rounds, Superconductor, Reaper, Twin Flywheel and eight more.
• Test flight: fly a satellite you don't own yet for one free sortie, at Mastery 10.

PERMANENT PROGRESS, NO WAITING
• Spend salvage on hull plating, cooling, extra sockets and Mastery. Every upgrade is instant.
• Three sectors, six enemy types and two bosses, then the Long Watch: an endless mode with a checkpoint every five waves.
• Hazard tiers: replay any cleared sector at up to 10 harder tiers, each with its own modifier and more salvage.
• Reclaimers gather salvage while you're away.
• Daily Orders that never expire, a Weekly Chart and the 30-step Keeper's Log.
• Game Center: 25 achievements and 3 leaderboards, one of them weekly.

PLAY YOUR WAY
• Pause any time, 1×, 1.5× or 2× speed, hold-to-spin buttons instead of dragging, high-contrast outlines, Reduce Motion support.
• Quit mid-sortie and pick up exactly where you left off.
• No account to make. The game plays offline; only Game Center and the optional ads need a connection.
• iPad: a wide Command Deck in landscape, with keyboard controls.

FAIR BY DESIGN
• Everything that changes how you play can be earned by playing. Paid looks are paint only, and plenty of looks are earned free.
• Nothing random is for sale: no loot boxes, no gacha.
• Optional purchases: the Founders Pack, cosmetic looks (the Aurora set, two finish sets and the Keeper's Log Supporter lane), satellites you'd like sooner, No ads, and salvage packs: salvage you'd earn by playing, sooner, at the same rate in every pack.
• Ads are optional rewarded videos, only when you choose one: after a sortie for +50% of the salvage you banked, after a breach to retry with your build, or to double a Reclaimers' haul. Never during a sortie, never forced. No ads claims every one of those rewards with a tap instead.
