What is Zasteroid?

Zasteroid is a fast-paced 2D top-down space shooter with roguelike progression. Pilot a starship through endless waves of quirky space foes — meteors, fast-striking interceptors, heavy tanks,

kamikazes, and colossal bosses that appear every five waves. Your ship auto-fires nonstop, so all you do is move: dodge enemy fire, hunt XP crystals, and level up to pick from 20+ upgrade

cards that reshape your build every run — piercing lasers, homing missiles, wide-spread shot, reactive shields, and more. Collect coins that persist even when you die and spend them in the

Hangar to unlock new ships and permanent upgrades. Graze enemy bullets to charge a devastating Super Weapon, complete bonus objectives each wave for extra coins, and survive as long as you can.

Every death is a fresh build and another "one more run."

How to play Zasteroid

Controls

• Desktop: Move the mouse — your ship follows the cursor. Use WASD or arrow keys as an alternative. Press Esc to pause.
• Mobile: Drag your finger anywhere on screen — the ship follows your touch. Tap the pause button (top-right) to pause.
• Your ship auto-fires constantly — you never need to press a shoot button. Just focus on dodging and positioning.

Objective

Survive endless waves of enemies and beat the boss that appears every fifth wave. Each destroyed enemy drops XP crystals. Fill the XP bar to level up.

Leveling & Upgrades

When you level up, the game slows down and shows three random upgrade cards. Pick one to shape your build — more bullets, piercing shots, shields, homing missiles, speed boosts, magnet range, and more. Each run plays differently thanks to the upgrades you choose.

Coins & Hangar

Enemies drop coins. Coins are permanent — you keep them even when you die. Spend them in the Hangar to unlock new ships (each with unique stats) and buy permanent upgrades like extra hull, engine tuning, and weapon calibration.

Tips

• Keep moving — standing still gets you hit.
• Prioritize survival upgrades early, then scale up your offense.
• Bosses appear every 5 waves — save your Super Weapon for them.
• Complete the wave objective (shown on screen) for bonus coins.
