Rogue Warrior is primarily a first-person shooter with tactical elements. The player assumes control of Richard "Demo Dick" Marcinko, also known as "Rogue Warrior". The primary goal for Marcinko begins as an infiltration mission to disrupt hostile missiles and evolves to prevent other potentially dangerous situations. The player starts each level armed with a Beretta 92FS (which has a silencer and an infinite number of magazines), a Heckler & Koch MP5A2 (which has neither), and five M26 grenades (out of a total of six the player can carry at once). The player can also carry a third weapon found in a level and swap out the MP5A2 for another gun the player finds (the 92FS can't be discarded).
