Set up Your Defenses

Theater Mechanicus - Mechanici Construction

Before starting the tower defense challenge, you must set up your defenses first during the Construction phase. Travelers can place mechanici on designated points in the map, which will help you defend your objective.

Reconstruct or Dismantle Mechanici

In-between phases, you can reconstruct Mechanici, or dismantle then to return some Veneficus Sigils.

Stop the Enemy

Theater Mechanicus - Defense

Once you have set your defenses up, it's time to stop enemies from reaching the monolith.

Monsters will not attack the player, and characters cannot deal damage to monsters. This is why Mechanicus placement is key to finishing each stage.

Special Features
