Aliens (Japan set 2): arcade Run and Gun
Konami's Aliens hit arcades in 1990, a side-scrolling run and gun shooter that faithfully adapts the sci-fi horror film. This 'Japan set 2' revision is one of several regional variants, likely tweaked for the Japanese market. The arcade hardware pushed detailed sprite work and atmospheric sound design, capturing the oppressive feel of the movie. Two players could team up as Colonial Marines, blasting through hordes of Xenomorphs across jungle and spaceship levels.
Gameplay puts you behind a marine armed with a rapid-fire machine gun. You move left to right, but you can duck, jump, and fire in eight directions using a second stick or button combos. Power-ups drop from destroyed enemies or cryo-tubes, upgrading your weapon to flamethrowers, shotguns, or smart guns. The core loop is straightforward: shoot everything, collect keys to open doors, and survive until the end of each stage. A boss fight caps off every area, demanding pattern recognition and quick reflexes.
What makes this Japan set interesting is its balance differences compared to other versions. Some enemy placements and item drops were adjusted, offering a slightly different challenge for veteran players. It also preserves the original high difficulty arcade experience, which demands memorization and precise movement. If you enjoy classic Konami shooters or want to see how a big-budget licensed arcade game played in 1990, this is worth a short session. Just don't expect any modern conveniences - it's pure quarter-munching action.
How to Play Aliens (Japan set 2) Online
Getting Started
Press Enter to start the game. If you are playing the Japan set 2 version, the title screen and menus are in Japanese. The first option on the screen is usually '1 Player Game' and the second is '2 Player Game'. Use the Arrow Keys to move the cursor and press X to confirm your selection. On the character select screen, you can choose between two marines - the only difference is cosmetic. Both play identically, so pick whichever you like.
The core gameplay is a side-scrolling run and gun. Use Arrow Keys to move your marine left, right, up, and down. Press S to fire your machine gun in the direction your character faces. You can also aim diagonally by pressing up or down while shooting. Press X to jump, which is useful for dodging ground-based attacks or reaching elevated platforms. Collect power-ups that appear as colored capsules: red for a flamethrower, blue for a shotgun, green for a smart gun. Each weapon has limited ammo, so conserve shots. Keys unlock doors to progress; make sure you grab them.
Enemies spawn both from the sides and from hatches in the background. Pay attention to the motion tracker on the HUD - it blinks when enemies are near. The game is tough; you have a health bar that depletes quickly. Use the environment to your advantage and learn enemy patterns. There is no save feature, so you must complete the game in one sitting. Co-op play is highly recommended, as a second player can revive you and share the firepower.
