Robugs

Take control of a nation of dwarves hidden in the mountains and lead them in a fight for survival against an invasion of mechanical insects. Robugs is a highly replayable tower defense game with procedurally generated paths and enemy waves.  Your mission is to secure a key region of your kingdom by building powerful tower, the foundation of your defense. Play endlessly as you discover new strategies.
CREATE YOUR OWN TOWER, FLOOR BY FLOOR
In Robugs, you don't build multiple towers along paths - instead, you construct a single, massive tower, expanding floor by floor. You can upgrade and customize each level of the tower to better fit the current battlefield situation. Choose wisely, as the right combination of floors will determine your chances of survival.

PROGRESS MAZING PATHS
The paths your enemies follow aren't predetermined - you can influence their progression. With each wave of enemies, they'll stretch in random directions and sometimes split, creating increasingly difficult formations. Each new playthrough offers a unique path layout and different challenges awaiting you in different regions of the world.

SPECIALIZE EVERY FLOOR TO FIT YOUR STRATEGY
Your tower is the heart of the entire strategy. Between waves of enemies, you can upgrade individual floors and combine them to create unique combinations and synergies. You have eight different floor types at your disposal, which you can further upgrade and customize. Every decision is crucial to the course of the game. In addition to the basic level, the game offers an endless mode and selectable challenges that modify the gameplay.
