Tower Lab

Tower Lab is an experimental sandbox game in which physics is the only means of defeating enemies. Robots have no health and the game shows no damage numbers. Instead, towers push, pull, bounce, grow, shrink and fling enemies off the edge of the map.

Players can place towers in any open space and move them freely, with no restrictions on building. Towers combine and affect one another, and the interactions between them arise from the physics of the game. A roguelite campaign lets players buy items, refresh the shop, remove cards and upgrade their setup over the course of a run. Towers can be upgraded, and players can change the mass of objects to alter risk and reward. Shrinking robots makes them easier to push, while growing them increases the rewards on offer. Projectiles can also be enlarged to make them more powerful.

The game includes a sandbox mode in which all content is available. Players can build and decorate their own levels and share them through Steam Workshop.
