Tower defense with roguelite runs and a loot-driven turret builder. Every kill counts three times: this second, this run, and between runs.
Build turrets from the modules you’ve looted: six slots, 88 modules, 15 base turrets to discover. Raise each turret’s MK with salvage.
Pick a threat (Standard, Veteran or Nightmare), an operation length (5, 10 or 15 alerts), up to five turrets, a sector and your card deck.
Fortify, maze, mount turrets. The Hive Alert climbs as you kill. Draft cards, chain kills, trigger Overdrive. Then the sector boss arrives.
Kill the boss and the run is won. Bank it with EVAC, or stay: Hive Fury adds salvage, up to half again, and the swarm comes back tougher and denser. Then share your Turret of the Run.
Projectile × accelerator decides what the turret is: Repeater, Mortar, Rail Sniper, Tesla Arc, Phase Laser and ten more base turrets, out of 81 pairs that all fire. Payload, hardware, field and core tune it. Modules drop from Common to Legendary, plus Uniques, and you keep them for good. You start with only the Repeater and the Mortar.

39 ability cards in 7 families: Ballistics, Energy, Explosives, Core, Economy, Command and Field. Unlock and level them with Research, then take a deck of 8 to 12 into each run. Kills fill the draft meter; when it’s full the game pauses and you pick one of three. Bosses grant extra picks.
The core sits at the centre of the fortress. The swarm never stops coming. Everything you do in a run buys it time.
Start with launch funds and earn credits by killing. Place fortifications on the grid, then mount turrets on them. Drag whole lines of foundations. You can build while paused.
Walls bend the aliens’ path. A longer path means more time under fire, and on higher threats a good maze is what keeps you alive.
Set each turret’s range and target point, so the mortar shells the choke and the rail covers the long road.
Press C for a short burst of raw power when a horde breaks through or the boss is on the walls. Or slot EMP Pulse, Artillery Strike or Emergency Barrier in its place.
Turrets rank up from their own kills, I to XII, and earn a callsign at rank VIII. Champions arrive alone, elites and Hive Lords lead packs; all of them drop modules, and the bosses drop the best.
Pause or run at 1× to 5×. INTEL and BASE pages show the run and your defences; radar and edge arrows show where hordes come from.
Every run rolls a swarm mutator (one on Standard, two on Veteran, three on Nightmare), and every sector ends with a boss. Both are shown before you deploy, so you know the question before you pick your loadout.
Bosses go for your turrets first, then the fortifications under them. Every boss telegraphs its moves.
Each sector earns up to three stars: a win, a win with the core above half, a win with it above 90%. Mountain Pass is where you start and the only finished sector so far; the other five are playable block-outs, each changing how the swarm reaches you.
