Reactor: Core Siege

Merge turrets into a ring of light and hold the core one more wave. Short roguelite runs, permanent upgrades, no subscription — and a Daily no purchase can touch.

Twelve turret slots ring a glowing reactor Core. The swarm descends from three lanes — dead center and both flanks — so a lopsided ring gets punished. Drag two matching turrets together to merge them a tier higher, place them where their roles line up, and hold. Reactor: Core Siege is a merge tower-defense roguelite you actually play — no auto-battler doing the work, no timer holding your progress hostage.

SKIP THE GRIND — NEVER THE RANK Most strategy games sell you power and call it fair. This one splits the two cleanly. Your own runs are yours to speed up however you like. But the Daily Descent is wallet-immune: every player gets the identical date-seeded board, it is 100% ad-free, and nothing you buy can touch it. Your result there is your merges, your placement, and your Overclock timing. Nothing else. Money can buy your time back. It can never buy your rank. New in 1.1: a daily Game Center leaderboard where everyone climbs that exact same board.

THE LOOP Waves descend toward the Core. Merge turrets from tier 1 up to tier 6, mix the three roles — Striker, Support, Splash — around the ring, and slam Overclock, a burst cooldown, on the right beat. Between waves you draft one of three cards: a new turret, a relic, or a lane modifier. Clear, draft, push deeper. Run it at 1x, or flip to 2x when you know what you're doing.

WHAT'S IN IT

• 12 turret types across a T1-T6 merge ramp — rockets, plasma, lasers
• 3 turret roles: Striker, Support, Splash
• 10 relics that bend the rules
• 6 lane-modifier cards
• 8 enemy types, from Scuttlers to Void Elites
• The Warden Core — a boss every 10 waves with three telegraphed attacks: Core Slam, Ring Sweep, Static Snare
• A 30-node, two-track prestige tree — 10 session nodes plus 20 prestige nodes
• An 8-rung ascension ladder, Warm-Up through Impervious
• A daily Game Center leaderboard + achievements — the ranked, wallet-immune surface
• A blueprint collection to complete
• The date-seeded Daily Descent, with a streak worth protecting

EVERY RUN CAN PLAY DIFFERENTLY The prestige tree doesn't just hand you bigger numbers. Most of the prestige track unlocks new turrets, new relics, and new lane modifiers that widen your draft pool — so a run weeks in draws from a deck your first run never saw.

HONEST PRICING — NO SUBSCRIPTION The whole game is free, and there is no subscription. Optional rewarded ads speed up your own progress if you choose to watch one. Prefer none at all? Ad-Free Forever is $3.99 once and it's yours for good — not a rental. There's also a one-time Starter Pack ($0.99) and a Spark Pack ($4.99) if you'd rather skip ahead in your own sandbox. No loot boxes. No spin-to-win. No countdown bundles. And none of it reaches the Daily.

PRIVATE AND OFFLINE Plays fully offline. No account, no sign-in, no server watching your runs. Your progress lives on your device.

Merge the ring. Time the Overclock. See how deep you can hold.
