The game uses a top-down perspective. Each level asks the player to guide a Grunt through a maze-like environment, collect useful objects, activate switches, defeat enemies, and reach the exit or rescue objective.

Weapons and tools give the Grunt different abilities. Players may break barriers, freeze hazards, cross special surfaces, or manipulate objects to open a route. Levels are completed in sequence, with later stages introducing more complex combinations of enemies, terrain, traps, and item effects.

Examine the entire area before using a weapon or consumable item. A tool that appears useful for combat may be required later to cross terrain or solve a puzzle.

Plan routes around one-way hazards and preserve useful items. When a puzzle seems impossible, check whether the needed object must be moved before an enemy is defeated or a switch is activated.
