Defence Force is a horizontal shooter categorized as a scramble-style shoot 'em up. The player navigates a spacecraft through a horizontally scrolling landscape, avoiding obstacles and engaging in combat with enemy forces. The objective is to progress through the levels while maintaining fuel reserves and surviving enemy attacks. The game features continual movement from left to right, which requires the player to react quickly to changing terrain and hazards. Endurance relies on the player's ability to avoid collisions and manage resources. The gameplay environment suggests a cave or tunnel setting, consistent with typical scramble shooters.
