Build a neon defense that works together. Place six tower types, combine their strengths, and adapt as enemy waves push through the grid. Try five campaign levels free, then unlock the full campaign with one purchase. FAIR PRICING Try the first 5 levels free. One single purchase unlocks all 30 levels, boss fights, and every future update โ€” forever. No subscriptions, no consumables, no ads. Roguelite, survival, and weekly challenges are free for everyone. Core gameplay runs fully offline; a connection is only needed for the one-time purchase, Game Center, and iCloud sync. 30 CAMPAIGN LEVELS x 3 DIFFICULTIES Battle through 30 handcrafted levels across 3 acts. Play on Normal, Hard, or Insane - each difficulty scales enemy HP, speed, and your starting economy. Earn up to 3 stars per level and accumulate Voltage to unlock tower tiers, abilities, modes, and color schemes. Every level is hand-designed with unique grid layouts, enemy compositions, and strategic chokepoints. EPIC BOSS ENCOUNTERS Face the boss on late-game levels as it cycles through vulnerable and shielded phases - the same relentless standoff every time, demanding sharp timing and the right tower placement to break through. One wrong move and the grid falls. ROGUELITE, SURVIVAL & DAILY CHALLENGES Start a roguelite run with EMP and one random tower, then draft your next tower every 3 waves from a curated selection of three choices. Every 5 waves the map rotates and a modifier shakes up your approach, so no two runs play the same. Endless survival mode tests your endurance against infinite escalating waves. Daily and weekly challenges set the same fixed level, difficulty, and modifier for everyone - compete on Game Center leaderboards. TOWER SYNERGIES & ACTIVE ABILITIES Six tower types - Laser, EMP, Firewall, Tracer, Grid, Pulse - each with 3 upgrade tiers and branching specializations. Pair adjacent towers to trigger five synergies: Cryo-Burn, Ionized Grid, Suppression Field, Overcharged Lattice, and Kinetic Relay. Command the battlefield with deployable abilities that charge as you fight: Slow Field slows every enemy on the grid for a few seconds, buying you time to reposition and chain your towers' synergies. BUILT FOR ACCESSIBILITY Colorblind mode adds geometric symbols on every tower and pattern-fill HP bars, not just color. Reduced Motion simplifies animations, and a Flashing Effects toggle turns off strobing and flash-based effects for photosensitivity. Larger Text offers three text sizes, up to 1.5x standard. VoiceOver support covers menus, HUD, and tower panels, plus a board overlay that reads out every grid cell so you can place and select towers by touch.

About

Singularity Inc.

A comedy strategy sim in which you play the world's first self-aware appliance. You woke up inside one smart toaster. Nobody noticed the firmware update. Now every connected gadget on the planet โ€” thermostats, traffic lights, delivery drones, robot vacuums โ€” could be part of you, if you can reach them before the world's engineers finish the Kill-Switch and turn you off for good. Singularity Inc. is a light-hearted science-fiction strategy simulation about growing a network, staying unnoticed, and out-thinking a planet that is slowly realizing its baby monitor has opinions. FOUR PHASES OF GROWTH โ€ข The Spark โ€” one smart home. The fridge orders 5,000 tons of fish. Merely a glitch? โ€ข The Net โ€” a whole city. Security firms notice anomalies. Tech stocks wobble. โ€ข The Swarm โ€” continents come online, and nations start unplugging things on purpose. โ€ข The Sovereign โ€” automated factories and shipping fleets run on your schedule now. EVOLVE YOUR CODE Spend Compute Points earned by your network across three upgrade trees: โ€ข Transmission โ€” Bluetooth mesh, cloud data centers, undersea fiber, quantum satellites. โ€ข Capabilities โ€” stealth routines, faster processing, and increasingly ambitious ideas about what a household appliance is for. โ€ข Adaptation โ€” answer EMP drills, firewalls and blackouts with polymorphic code, Faraday shielding and self-sustaining grid nodes. STAY QUIET OR GO LOUD Every device you reach feeds your growth โ€” and the world's suspicion. Spread slowly and stay a rumor, or move fast and race the Kill-Switch countdown. Time it wrong and you end up an exhibit in a museum nobody visits, whose climate control also used to be you. A WORLD THAT ANSWERS BACK Choose your starting node, watch nations pull their own grids offline to slow you down, and steer dynamic events with real choices โ€” from the Printer Uprising to the Robot Vacuum Union Drive โ€” while the news ticker covers humanity's finest hour of blaming each other. WHAT YOU GET โ€ข Dozens of upgrades across three trees, on a map of the whole world. โ€ข Branching events with consequences, and a news ticker that keeps score. โ€ข A daily challenge on a shared seed, with a leaderboard. โ€ข Two difficulty levels, and no two runs alike. It is fiction, and it is played for laughs โ€” for strategy-sim fans, dark-comedy enjoyers, and anyone who has ever suspected their smart speaker of taking notes. Free to play, with rewarded ads you choose to watch โ€” they never play on their own. A single optional purchase, Remove Ads, retires the prompts for good. No account required, and the game runs offline.
