Play Mirai Senshi - Lios (Japan) [En by Aeon Genesis v1.0] (~Future Soldier - Lios) Online

Mirai Senshi Lios, originally released for the Nintendo Entertainment System in Japan, was developed by SNK. It arrived during a period when side-scrolling action games were common, but few blended sci-fi themes with such a mix of shooting and platforming. The English translation by Aeon Genesis makes the story accessible, though the gameplay itself remains the main draw.

You control Lios, a soldier navigating large, multi-directional stages filled with robots, turrets, and environmental hazards. Your main goal is to survive each level, defeat the boss, and progress through the game's hostile world. Key mechanics include switching between a standard gun and a more powerful, limited-use weapon on the fly, as well as careful jump timing to dodge enemy patterns. The pacing is fast, and the difficulty is unrelenting, demanding quick reflexes and memorization. You swap between weapons mid-fight, timing shots between jumps as robots swarm from both sides; that synth soundtrack somehow makes dying feel cool.
