Contra Doom aims to replicate the gameplay of Contra, particularly Contra III: The Alien Wars, including the ability to hold two weapons at a time, one hit deaths, and scoring points. While Contra III is best represented here, some elements from other games are taken, such as Super Contra (Arcade), Contra: Hard Corps, and Contra 4.
