Space Outpost is a hand-crafted sci-fi tower defense game, built for one-handed portrait play and fully playable offline. The sun is dying. Kyro is the only fuel that can keep it burning, and it is mined on the most hostile worlds in the system. You command the outpost that holds them. Hold the line, Commander. A growing roster of planets, an escalating bestiary, mobile strike units, and orbital powerups mean no two stands play the same. HOLD THE LINE • Battle across a campaign of unique planets, from the pale dust of Lunar Field to the black cliffs of the Obsidian Throne, with more worlds on the way. • Each world has its own terrain, lanes, and threats, ramping from Easy to Nightmare. • Clear milestone waves at 25, 50, 75, and 100 for escalating Kyro payloads, then hold out as long as you can in endless waves past 100. BUILD YOUR DEFENSE • Stack guns and support buildings: Laser, Plasma, Burst, Beam, and Nova towers, plus Barracks, Repair Bay, Refinery, Trading Post, Targeting Uplink, and Shield Pylon. • Upgrade every tower through multiple tiers. • Mine rock, raise walls, and lay mines to shape the kill zone. GO ON THE OFFENSIVE • Deploy mobile units that march out and fight: Troopers, Snipers, Rocket Troopers, and Medic Drones. • Call in single-use powerups: Meteor strikes, Orbital Strikes flown by your own ship, Fission Bombs, Supply drops, field Repair, Freeze, Overclock, Trooper Drops, and Energy Boosters that triple one turret's damage for thirty waves. KNOW YOUR ENEMY • Face Grunts, Runners, Brutes, swarming Mites, shielded Bulwarks, tower-diving Reavers, splitters, flyers, freeze-proof Wraiths, and self-healing Hive Crawlers. • Survive boss waves: Warlords, Warbringers, Titans, Colossus brood-carriers, and the flying Dreadnought capital ship. • Study every threat in the in-game Armory before it lands on your doorstep. TWO WAYS TO PLAY • Classic: repair your base between waves and dig in for the long haul. • Sudden Death: low base HP, no repairs. One leak ends the run. Higher Kyro payouts for the brave. SPEND KYRO, UNLOCK EVERYTHING • Earn Kyro by clearing milestone waves, then permanently unlock new towers, units, and powerups in the Armory. • Plays fully offline: no account, no internet required. • Designed for portrait, one-handed play. Hold the line. Every gram of Kyro buys the sun another day.
