About this game

Turn-based artillery strategy, one perfect shot at a time. Sling Theory is an offline strategy game that drops you onto destructible neon battlefields, where you set your angle, adjust for wind, and blast the enemy squad off the map with 42 wildly different weapons.

Two slime factions collide: the cool teal VOX and the burning orange PYRE. Every shot reshapes the ground, so the battlefield you start on is never the one you finish on.

If you grew up on turn-based artillery duels, you know the feeling. Line up the arc, hold your breath, and watch the whole ridge come down.

WHAT YOU GET

- A 100-mission campaign across 10 themed chapters, each ending in its own boss fight.
- 42 weapons: grenades, mortars, snipers, cluster bombs, homing shots, airstrikes, mines, napalm, gravity wells and more, each with a distinct feel and its own sound.
- A deep loadout system. Unlock weapons, weigh them against your carry limit, and build an arsenal that suits your style, with presets, sorting and auto-fill.
- Slime upgrades: toughen your squad, raise your carry weight, resist fire and poison, or field more slimes per battle.
- A ranked ladder and knockout tournaments against escalating AI opponents.
- Custom battles with shareable codes. Send a friend the code and you both take on the exact same map, wind and weapon set.
- Fully destructible terrain, plus wind, water, crates, mines and oil drums that change every single turn.
- Handcrafted neon art, punchy sound design, and physics that reward patience over spam.

WHY TURN-BASED ARTILLERY

There is no reflex test here and no twitch aiming. Just angle, power, wind and terrain. Read the board, pick the right weapon for the job, and take the shot. Miss, and the enemy gets a free turn to bury you. It is a slower, more deliberate kind of strategy game, and every mission is a small puzzle you solve with the arsenal you chose to bring.

PLAYS YOUR WAY

- 100% offline. This is a single player game that needs no internet and no wifi, so it works on a plane, on the metro, or anywhere with no signal.
- No ads, ever. No banners, no forced videos, no interstitials interrupting your turn.
- No accounts, no sign-up, no tracking. All progress is saved on your device.
- Portrait play with quick turns. Good for a short bus ride or a long session on the couch.
- No energy timers and no waiting. Play as many missions as you like.

OPTIONAL EXPANSION

The Singularity adds the final chapter, the OMEGA boss, and a gravity-well weapon that drags every slime toward a single point before collapsing, for multi-kills nothing else can reach. One-time purchase, no subscription, and it restores on your Google account.

If you like turn-based strategy, artillery duels, destructible terrain and offline games you can actually finish, Sling Theory was built for you.

Aim true. Mind the wind. Sling Theory.
