What are keyshops?About The Black Siege
Humanity’s last Rocketship is damaged. It is the only way out, but it cannot launch yet. The base is surrounded, the plagued zombies are closing in, and time is running out. You are the last commander. Build your army, upgrade your turrets, command your formations, and survive each wave while your engineers repair the Rocketship.
The goal is not to fight forever. But to escape before your headquarters fall.
The Engineers
Your engineers are the backbone of your army's strength and your chance of escape. Hire them with gold, command them to produce Hex Screws, repair your ship, and maintain your base. The Hex Screw is the resource you need to repair your ship and reload your turret's ammo. It can also be used to trade for power-ups in the shop roll. Once your engineers reach 20,000 Repair points for your Rocketship, you will be able to board it and escape the siege.
Power-ups and Army Units
After every wave you survive, a shop opens where you can trade your Gold and Hex Screws for stronger power-ups and army units. Buy power-ups like lightning drones that ricochet between enemies, or recruit stronger army units that can withstand multiple zombie attacks. Build your army, improve your defenses, and strategize your run by commanding your army's formation.
Can you survive the siege?
Spend your resources to survive longer, or risk everything to repair the rocket faster. The longer you stay in siege, the more difficult it is to defend. Repair your Rocker Ship as fast as you can and escape The Black Siege. Trade your Hex Screws for power-ups that can hasten your hex screw production and the speed of your engineers. Form your armies in a strategic formation, build them by buying more units in the shop, and assist them with your wits.
