In Footgun: Underground, balls are the central gameplay element and skill is definitely required. With ball control and the use of level environments such as walls, platforms, ceilings or even other balls, monsters can and must also be eliminated via barriers. After each successfully completed level, which is randomly generated, the player's character and balls can be upgraded with various skills and effects. Defeated boss monsters naturally unlock particularly valuable upgrades and loot. Different player characters with different characteristics and permadeath make each run unique.
