Defend Mars in a fast arcade space shooter built for instant action. Asteroids are falling. Bosses are approaching. Deadly ice obstacles block your path. Take control of your ship, destroy the incoming threat, collect upgrades, and keep Mars alive for as long as you can. Tutorial toasts guide you during the first battles, so you quickly understand what to do: move your ship, destroy asteroids, collect gold and XP, use shields, charge your ultimate weapon, dodge ice, and survive each wave. CLASSIC MODE Fight through 100 tuned levels with rising enemy HP, speed, pressure, boss behavior, and difficulty. Destroy small, medium, large, and gold asteroids, collect XP and gold, unlock stronger ships, and improve your firepower as the challenge grows. SURVIVAL MODE Enter an endless run where every second matters. Destroy enemies in the center combat lane, break upgrade shells to gain new ships and buffs, and collect ammo gates to charge your ultimate weapon. Each run starts from MK1. Survive long enough, upgrade to MK5, and push your score higher. 5 SHIPS TO MASTER Progress from MK1 to MK5 and feel your firepower grow with every upgrade. Each ship has more barrels, a stronger combat role, and its own ultimate weapon: • MK1: one barrel and a laser beam ultimate • MK2: two barrels and a bomb ultimate • MK3: three barrels and a stronger laser ultimate • MK4: four barrels and a giant bomb ultimate with increased explosion radius • MK5: five barrels and the most powerful laser ultimate Laser ultimates become much more destructive as you progress from MK1 to MK3 and finally to MK5. Bomb ultimates also evolve, with MK4 delivering a larger explosion radius for massive battlefield clearing. View your ships with a stylish 3D rotation effect in the upgrade screen. POWER-UPS AND ULTIMATES Collect shields, regeneration, damage boosts, shot multipliers, ammo gates, and other combat bonuses. Use laser and bomb ultimates at the right moment to clear the battlefield. In Survival mode, special bomb runes can add extra explosive power during long runs. BOSSES, OBSTACLES, AND LEADERBOARDS Dodge unkillable ice, destroy gold asteroids for valuable rewards, defeat Armageddon-style bosses, and compete for your best Survival score on the Game Center leaderboard. Mars is under attack. Upgrade your ship, master the chaos, and become the defender of the red planet.
