This page stays inside what the official store, developer updates, or current public build establishes. Exact statistics, hidden requirements, permanent rankings, and unreleased outcomes are not inferred from genre conventions. Where a detail remains unavailable, it is marked as not officially confirmed as of 2026-09-05.
Confirmed Mechanics

|---|---|---|
| 1 | Enemies have no health and are defeated through displacement. | Official Tower Lab Steam page |
| 2 | Grow or shrink changes physical behavior and reward risk. | Official Tower Lab updates and patch notes |
| 3 | Iron enemies are heavier and require more knockback. | Official Tower Lab Steam page |
Steps
- Identify the direction in Identify the direction in which an enemy can be removed.
- Choose a force or Choose a force or scale effect that makes that movement easier.
- Aim or rotate the Aim or rotate the tower so its output supports that vector.
- Observe the collision chain, Observe the collision chain, then change one physical variable at a time.
After each step, check the visible state before spending another action or resource. That keeps a changed build, procedural layout, or failed attempt from turning one bad assumption into a full restart.
Requirements
- A stage with an exposed edge or removal condition
- At least one tower or physics card
- An understanding of incoming enemy mass/type
How to Check the Result
Confirm the named interface state, objective change, resource movement, roster change, or physical outcome described above. If the current build displays a different rule, keep the official page's broad system description but treat the live prompt as the current operational instruction. Do not substitute an old screenshot or an unlabeled third-party value for the active build.
Common Problems
- Problem: More projectiles can reduce reliability when they collide unpredictably.
- Problem: Opposing forces may cancel; align towers around one removal direction.
- Problem: A heavier unit needs greater or repeated displacement, not a fabricated damage stat.

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.

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.
