Murky Horizon: Tower Defense
Twin-stick survival shooter
Free · Designed for iPad. Not verified for macOS.
Night is falling and the lizards are coming. Hold the bunker for forty rounds.
Murky Horizon is a twin-stick shooter crossed with tower defense. You are one marine with a rifle, a bunker to protect, and a few seconds between waves to build. Lizards pour in from every edge of the map and head straight for the hatch. When the bunker falls, the run is over: you respawn, it does not.
SHOOT
• Drag on the left to move. Hold FIRE to shoot the way you're facing, or drag out from it to aim
• Hold CHARGE for slower shots that pierce a whole line
• Throw flares at night, when the dark swallows everything past your muzzle flash
BUILD
• Rocket turrets, ice turrets, lasers, and barriers you can drag into a whole wall
• Upgrade anything you own. Sell it for a full refund and rebuild somewhere smarter
• Every dollar comes from kills. Spend it between waves, or start the next one early
SURVIVE
• 40 rounds, with a day–night cycle that changes how each one plays
• Boss waves. "Berserkers... everywhere."
• Four difficulties, from Easy to Nightmare
• Your best runs, kept on your device
NO CATCH
• Free. No ads, no in-app purchases, no account
• Plays offline
• No analytics, no tracking. Nothing leaves your phone
Murky Horizon began life as a 2009 console indie game and has been rebuilt from the original art, audio and shaders.
