• Mottomo Abunai Deka
Release Date: 1989
Genre: Action
Players: 1–2

• Description - Mottomo Abunai Deka is a side-scrolling action game based on the Japanese detective drama. You play as two cops fighting through waves of enemies using handguns and occasional weapon pickups. The game is known for its clunky controls, heavy slowdown, and rough overall design, with awkward jumping and enemy placement that make progression difficult.

Wit's

• Wit’s
Release Date: 1989
Genre: Action
Players: 1–4

• Description - Wit’s is a competitive arena action game similar to the light cycle segments from Tron or Snake. Players move around a rectangular playfield, leaving a trail behind them that becomes a hazard. The goal is to outlast opponents by avoiding collisions while forcing them into your path. Players can speed up and have a limited jump ability to escape tight situations.

• Co-op Experience - This is primarily a competitive multiplayer game rather than traditional co-op, but there is a mode that allows two players to team up against the computer. Also, up to four players can play simultaneously, competing to survive the longest or score the most points across rounds.

Astro Robo Sasa

• Astro Robo Sasa
Release Date: 1985
Genre: Action Shooter
Players: 1–2

• Description - Astro Robo Sasa is a single-screen action shooter built around a pretty unique mechanic. Instead of just using your gun to attack, every shot also pushes your character in the opposite direction, so movement and combat are tied together. Each stage is about collecting energy while avoiding enemies, and because your ammo and health come from the same meter, every shot matters. The game moves through different gravity-based environments including indoor stages, underwater areas, and outer space.

• Co-op Experience - Two players play simultaneously, with Player 2 controlling Nana. Both characters have their own energy meter and work through the same single-screen stages together, but there’s a catch: players can accidentally shoot and damage each other. It makes co-op feel more chaotic and a lot less forgiving.

The game leans into its Sanrio theme with a lighter, more accessible design aimed at younger players.

• Co-op Experience - Two players play simultaneously, working through maze-like stages together. Both players can place water balloons and help clear paths, making it a more relaxed, cooperative version of the Bomberman-style formula.
