About TDG: Tower Defense

TDG is a focused military tower defense game from Rubbleline Games. Hold the line across a full 10-wave run, spend scrap wisely, and keep your base standing when the map changes under fire.

Hold the line

Build on a procedural battlefield. Place emplacements, upgrade them through tiers, and sell or repair between waves. Enemy vehicles push harder as the run goes on—and new routes open so your early plan is never permanent.

Procedural maps so every deployment feels different
Four tower types with upgrades, sell, and repair
Path openings mid-run that force you to adapt
