ONE TOWER. ENDLESS WAVES.
You get a single tower at the centre of the arena. Everything else is a decision about where the money goes.
Every wave you clear pays out immediately, and you spend it mid-run: damage, attack speed, crit chance, crit factor. Six weapon mounts fire at once — Tesla coil, mortar, beam laser, flak cannon, ricochet shredder, railgun — and each has its own upgrade lines. Run ends, cash converts, and the permanent side of the game opens up.
THE CONSTELLATION
453 passive nodes across six arms and six keystones. Points come from your progression level, not from clearing an arbitrary wave, so the tree is open from early on and keeps paying out for hundreds of runs. Sockets take jewels that rewrite what the nodes around them do.
BUILT AS A PREMIUM GAME
No ads. No timers. No energy bars. No currency sold for real money. You buy it once and the whole game is there.
WHAT'S IN IT
14 weapons, 6 simultaneous mounts, 10 sectors of escalating difficulty, a 453-node passive tree, jewel sockets and attunement, 64 achievements, offline earnings, and a workshop of permanent upgrades that raise where every future run begins.
