Engineer is a Tower. All upgrades and prices are same but 9-Inch Nails costs 700 instead of 450, Faster Engineering costs 350 instead of 400 and Cleansing Foam costs 750 instead of 800.


  • Used with Regen Rainbows and Regen Browns, Cleansing Foam is extremely OP due to removing Camo, Regen and cracking through Lead.
    • DDTs have Camgrow Black and Lead properties. It is still unknown that what effect comes in. Maybe 6 neither Camo nor Regen browns, maybe 1 HP damage.
  • Some prices are changed.
  • Used with Normal, Camo, Regen or Both Leads P1U3 is extremely OP, especially Rushes.
