The Black Siege

In The Black Siege, you command humanity’s last army as plagued zombies close in on the base. The damaged Rocketship is the only way out, but it cannot launch until it is repaired. Build your army, upgrade turrets, direct formations and survive waves while your engineers work on the ship. Your objective is to escape before the headquarters fall, rather than fight indefinitely.

Repair the Rocketship

Engineers are central to strengthening your army and making an escape. You hire them with gold and command them to produce Hex Screws, repair the ship and maintain the base. Hex Screws are needed to repair the Rocketship and reload turret ammo, and you can also trade them for power-ups in the shop. When the engineers reach 20,000 Repair points for the Rocketship, you can board it and escape the siege.

Build your forces

After each wave you survive, a shop opens where you can spend gold and Hex Screws on power-ups and army units. Power-ups include lightning drones that ricochet between enemies, as well as effects that can speed up Hex Screw production and your engineers. You can recruit stronger units that withstand multiple zombie attacks, then arrange your army in formations and assist it as you defend.

Survive the siege

The longer you remain under siege, the harder the base becomes to defend. You must choose whether to spend resources on surviving longer or risk them to repair the Rocketship faster, while building your forces and improving your defenses. Repair the ship quickly enough to escape before the headquarters fall.
