The gameplay is fast-paced, allowing the player to choose between sneaking through levels or running in guns blazing. The game features a variety of real-world weaponry, including the SPAS-12 shotgun and AK-47 assault rifle. However, even Marcinko is not invulnerable, so players must use cover to avoid taking damage. The game also includes a multiplayer mode for up to eight players, with options for Deathmatch or Team-Deathmatch on maps inspired by the single-player campaign.
