LoopForge

Merge turrets, defend the loop, clear campaign rings, climb Endless ranks.

LoopForge is a merge tower defense — enemies march the outer loop while you forge firepower on the pads inside.

Pull turrets from the hold bay, drag them onto pads, and merge matching type and tier up to T5. Matching pieces in the tray must be placed first — then drop the twin onto that pad (or drag pad onto pad) to fuse.

Survive runners, tanks, swarms, and bosses across 40 campaign rings. Guard three hearts: every leak costs one, and hearts left at clear set your star rank. Endless mode has no wave cap — your best score syncs to the global leaderboard under your callsign and portrait.

Unlock the Armory as you climb: Bolt, Arc, Pierce, Slow, and Mortar. Upgrade each turret’s damage and minimum spawn tier. Spend scrap on forge upgrades — spawn cadence, starter bay, rail velocity, forge heat, hold slots, and forge pads (25%→100% build space). Buy special protocols — Overdrive, Gravity Drag, Scrap Nova, Cryo Lock — equip one on Home and fire from the center well when the cooldown ring is full.

Contextual coach tips guide place, merge, pads, shop, and ranks. No ads. Progress is local; Endless scores sync for the scoreboard.

Place. Merge. Hold the loop.
