More about this game
Your goal is to destroy the asteroid before the 180-second timer runs out. Start by manually tapping the mountain to reduce its 4200 health and earn $1 per tap. Use this cash to hire up to 10 monster workers who automate the mining process. Ore is converted into cash at the processing plant. Purchase upgrades across five tech trees to boost mining speed, storage capacity, and rocket damage. The run ends when your rockets deplete the asteroid's 3800 health, or when it crashes into your base.
Tips
- Always keep your processing plant upgraded; if your hopper fills up, your workers will queue up and stop mining.
- Gems are worth $62 compared to gold's $28, so unlocking the Gem Sorter upgrade significantly boosts your income.
- Don't ignore the Meteor Defense tree; you need enough rocket damage to chew through the asteroid's 3800 health before it lands.
FAQ
- How do I get more workers?
- Open the Workers tab in the upgrades menu. You can hire your first monster for $12, and eventually unlock up to 10 workers through the Tunnel Squad and Foremonster nodes.
- Why are my monsters just standing at the plant?
- Your hopper has reached its storage capacity. You need to buy Plant upgrades like the Bigger Hopper to increase your storage limit so workers can deposit their ore.
- How do I stop the asteroid?
- Your base automatically fires rockets at the asteroid. You must spend cash in the Meteor Defense tab to increase your rocket fire rate and damage to destroy it in time.
