Each of these "3D maze" stages are set inside the corridor of an enemy base in which the player must fight through the base's defenses in order to reach the core of the base. In addition to the standard side view stages, Contra also features stages in which the player character is seen from behind and must move towards the background in order to proceed. There are a total of ten areas in the game. All the power-ups in the arcade version are represented by Eagle-shaped letter icons with the exception of the Machine Gun and Laser.

There also two additional supplemental power-ups: a Rapid Fire power-up which increases the player's firing speed, as well as a Barrier that will grant the player temporary invincibility for a few seconds. There are a total of four weapons the player can retrieve from flying weapon capsules or pill-box sensors: a Machine Gun, a Laser Gun, a Fire Gun, and a Spread Gun. A single hit from any enemy, bullet, or other hazard will instantly kill the player character, and also discard the current weapon from the player's disposal. The player can also jump, move and fire in eight directions, as well as move or jump simultaneously while firing. The main character is equipped with a rifle with an unlimited amount of ammunition.
