Contra 4 ROM (NDS) – USA Download

The year is 2638, two years after the events of Contra III: The Alien Wars. Strange readings are detected on the Galuga archipelago, and a new alien threat known as Black Viper begins attacking Earth. The Earth Federation sends its four strongest Contra Force commandos to stop it: series heroes Bill Rizer and Lance Bean, joined by two new soldiers, Mad Dog and Scorpion. Together they must fight through the islands and wipe out the alien invasion.

Contra 4 is a classic side-scrolling run-and-gun game. You run, jump and shoot your way through enemy soldiers, alien creatures and giant bosses, and one hit is usually enough to lose a life. The action takes place across both DS screens at once. Enemies and bosses can attack from the top or bottom screen, and the new grappling hook lets you latch onto railings and climb between the two screens. Weapons work like the classic games. You can carry two weapons and switch between them, and if you pick up the same weapon twice, it powers up into a stronger version. You can also throw away a weapon you don't want. Arcade Mode has nine stages: six side-scrolling stages and three behind-the-back tunnel stages. You can play on Easy, Normal or Hard. After you finish Arcade Mode once, Challenge Mode unlocks, with 40 special challenges to complete.

1. Download the ROM file and extract the .zip archive to get the .nds file. 2. Install a DS emulator: melonDS or DeSmuME on PC and Mac, DraStic or melonDS on Android, or Delta on iPhone. 3. Open the emulator and load the .nds file. 4. Set the screen layout so both screens are visible, because enemies attack from both. 5. Start on Easy if you're new to Contra. The game gives you more lives and is much more forgiving. Tip: When you find a good weapon, pick it up a second time to power it up. The upgraded Spread and Laser weapons make bosses much easier.

melonDS is the best choice on PC and Mac. It is free, accurate and runs Contra 4 at full speed, and it lets you choose how the two screens are arranged on your monitor. On Android, DraStic runs the game smoothly even on older phones. On iPhone and iPad, Delta is the easiest option.
