Contra: Secondary Weapon Slot and Remote Barrier is an inventive ROM hack of Konami’s 1988 run-and-gun classic for the NES. Created by modder magus, this upgrade modernizes the original game by adding a dedicated secondary weapon slot, allowing you to carry two different guns and swap between them on the fly. It also revamps the Barrier power-up, letting you store it and activate a remote shield on command.
Your objective remains the same: blast your way through enemy-filled stages and defeat the alien Red Falcon forces. The game uses standard browser-mapped NES controls. Use the Arrow Keys to move and aim, Z to shoot (B button), and X to jump (A button). The hack introduces new mechanics mapped to the NES Select button (Shift): tap it quickly to switch between your primary and secondary weapons, or hold it for more than two seconds to deploy your Remote Barrier.
Tips:
- Keep the powerful Spread Gun safely in your secondary slot, using your primary slot to pick up and experiment with other drops like the Laser.
- If you are playing in two-player mode, picking up a Barrier will now grant an invincibility shield to both players at the same time.
