Earth is under attack from every direction—UFOs, battle drones, and deadly comets. You are the last line of defense. Build your own war machine from blocks and turn it into the ultimate survival rig.
Every block shapes your playstyle: add shields and armor to endure the chaos, mount weapons from pistols and bazookas to lasers, install economy modules to earn extra cash mid-fight, and use upgrade blocks to boost damage, fire rate, reload speed, and more.
Each level is a run of 10 consecutive survival stages with new enemy waves. Between stages, shop for new parts and merge identical blocks to level them up and unlock stronger builds. Different arenas demand different strategies—adapt your setup and prove you can defend Earth!
How to play
Controls are minimal—action and strategy are not:
• Move left/right to dodge incoming fire and falling comets.
• Mobile: drag or hold your finger on the screen to move—while your finger is down, your weapons keep firing automatically.
How a level works:
• A level has 10 stages. Clear every wave and survive.
• Between stages, open the shop to buy new blocks for your machine.
• Merge identical blocks to upgrade them and gain a big power spike.
• Adjust your build to each arena: stack defense, invest in economy, or go all-in on firepower to find the strongest combo.
