The gameplay is similar to Neo Contra with a behind-the-back view where the player uses various weapons like machine guns and rocket launchers, along with the Delta 6 Accelerator Suit that makes the player invulnerable for a short time. The player must fight their way through a horde of enemies including soldiers, tanks, and jet fighters, as well as standard end-of-level bosses.
The player can choose from 12 different Joes, but only a set at the beginning and unlocking more by completing missions. Each Joe has their own weapon and strengths depending on their rank – Commandos are great at close range, Heavy Weapons are good at shooting from long distances, while Soldiers are a mix of both. The game also features various vehicles scattered throughout the stages and a two-player co-op option where a friend can join at any time.
