Common Problems

Tower Lab Tower Interactions and Combinations
Build combinations around real collisions: bounce Mine Tower mines from the Deflector panel, move Bomb Tower projectiles with Fan Towers, and shrink enemies to make them easier to push. These are confirmed interactions, not scripted combo bonuses.
Verified guideTower Lab Beginner Guide
Win by pushing enemies off the route, not by reducing health. Start with one reliable displacement interaction, place and rotate towers during BUILD, observe a complete ATTACK wave, then add cards or upgrades that reinforce the same physical result.
Verified guideTower Lab Physics System Explained
Tower Lab replaces damage scaling with force, mass, size, stability, friction, and displacement. Grow, shrink, split, merge, push, pull, bounce, hook, fling, or redirect objects so enemies leave the route; heavier enemies need more effective knockback.
