Theater Mechanicus Stage 3 (Difficulty 4) - Guide & Tips
Place Mark I Mechanicus At The Start

To be able to gather more Veneficus Points and construct machines faster, place Recovery Mechanicus together with several damage giving mechanicus.
Replace Mark I Later In-Game
In later part of the stage, recovery mechanicus should be reconstructed as an attacking piece or destroyed to make way for other Mechanicus.
Make Use Of Ambush Mines

The enemies in this stage will come from 3 different gates making your defenses weak because of the limited amount of mechanicus that can be built. Placing Ambush Mines near the exit will surely destroy those already damaged enemies.
Leaving 2 Mechanicus Slot For Mines Is Recommended
These mines will be used for emergency situations or instances wherein enemies were able to penetrate the mechanicus that you built.
