Contra: eight stages, one hit, thirty lives
Contra arrived on the NES in 1988 as a port of Konami’s arcade game and became the definition of the run-and-gun: two commandos, a jungle full of soldiers, and a rule that one bullet kills you. What made it a classic was not cruelty but rhythm. Enemies arrive in patterns you can learn, the spread gun turns the screen into a fan of bullets, and the eight stages — jungle, two bases seen from behind, a waterfall, snowfield, energy zone, hangar and the alien lair — each play differently. It is also the game that made the Konami code famous, because thirty lives is exactly what a first run needs.
This page runs the NES version in an emulator inside your browser, with the game data served from contra.ee. Nothing installs; press Play and the title screen appears in a few seconds. The emulator’s toolbar has save-state buttons if you want to keep a stage (keys 1 and 2 quick-save and quick-load), and a second player can join with a gamepad, or on the keyboard once player two’s keys are set in the emulator’s control settings.
Controls & Mechanics
| Action | Control | Purpose |
|---|---|---|
| Move / aim | Arrow keys | Up shoots upward; Down lies flat; diagonals while moving |
| Fire / jump | X / Z | Down + Z drops through a platform |
| Start / Select | Enter / V | Konami code on the title screen: ↑↑↓↓←→←→ X Z Enter |
Reaching the alien lair
- Take the spread gun and keep it: The S capsule is the best weapon in the game. Once you have it, play carefully; dying loses it and the last three stages are much harder with the rifle.
- Keep moving in the base stages: In Base 1 and Base 2 the view goes behind your soldier. Shoot the core on the back wall of each room to open the way forward, and keep moving while the guards shoot at you.
- Learn the waterfall climb: Stage three scrolls upward instead of sideways, and dropping off the bottom edge of the screen costs a life. Take each jump only when you can see where you will land.
Key Features
- Two-player co-op: Pick 2 Players on the title screen; player two needs a gamepad or their own keys set in the emulator.
- Save states: Freeze a stage and reload it from the emulator’s toolbar. A stage-eight save is not cheating, it is respect.
- Served from this site: The game data loads from contra.ee and the open-source EmulatorJS player from its public CDN, not from an ad-gated third party.
