Cannon Fodder puts the player in command of a fragile military squad tasked with completing 72 levels across diverse environments—from jungles and snow-covered wastelands to arid deserts. Armed with machine guns that pack considerable firepower early on, the squad of up to five soldiers must navigate terrain hazards like rivers, quicksand, and mines while contending with increasingly formidable enemy forces, including infantry, vehicles, and fortified structures. Since standard weapons prove useless against buildings and armored targets, players must scavenge limited supplies of grenades and rockets, carefully balancing resource expenditure against mission demands. The strategy layer demands caution and tactical positioning; soldiers can be split into smaller units to flank enemies or probe dangerous ground without unnecessary casualties. Success hinges on blending real-time gunplay with deliberate squad management, as the overwhelming numerical advantage of enemy forces means reckless advances invariably spell disaster.
