About the Game
Tower Lab is an experimental sandbox game about using physics as a weapon to push robots off the map.
Pure physics, enemies have no health
There are no damage numbers. Towers push, pull, bounce, grow, shrink, and fling enemies off the map.
Build without restriction
Place towers in any open space. Move them freely. Experiment with different setups.
Combine Towers
Towers combine and affect each other. Their synergies emerge from physical interactions.
Improve your run
Buy items, refresh the shop, remove cards, and upgrade your setup throughout a roguelite campaign.
Upgrade towers
Change mass, control risk and reward
Shrink robots to make them easier to push, or risk growing them to gain increased rewards.
Grow projectiles to make them more powerful.
Sandbox and Workshop
Build and decorate levels, then share them on Steam Workshop. In sandbox mode, you can use everything.

Gameplay
Reduced width of oversized unit colliders to better fit the models and reduce chances of stuck enemies.
Removed run failed banner from the ending sequence of Endless Mode.
Increased Sandbox decorative object cap from 300 to 600. We will display this limit in the UI in an upcoming update
Disabled decorative spawn point and unit spawning from Region 1 Level 1’s background decor

Fixed several cases where units would frequently get trapped or hang off the edge of a platform
Remove Platform card can now properly target non-essential platforms in Endless Mode
Add Platform now properly updates the next generated platform’s spawn preview
Cube/Sphere physics objects now render properly in sandbox mode
Balance
Reduced amount of enemies in Endless Mode waves 1-25 (starting at ~40% original total, scaling to current value by wave 25)
Performance
Lowered URP quality-tier settings that were unnecessarily higher than needed
Improved expensive calculations in rope collision and unit crowding
Art
Updated level decor foliage to more closely match surface in early campaign levels
Reduced reflectivity of Bouncy Gel trap
Known Issues:
Add Platform preview may not be rendering properly on Mac.
Thank you all for the bug reports!
Fixed an issue that prevented changing languages in Settings. You may need to select your preferred language again.
Thank you to the player who reported this through the in-game bug report tool!
