Play Cosmo Police Galivan (Japan) Online
You slash through alien hordes with a delayed sword swing, hop into a transforming mech, and explore planets in this clunky-but-charming NES sci-fi oddity—just brace for some brutal difficulty spikes.
Cosmo Police Galivan is a 1988 Nintendo Entertainment System release from Nichibutsu, a company better known for arcade shooters. It stands out as a side-scrolling action platformer with a sci-fi theme, a less common genre mix on the NES at the time, and it carries a certain rough, experimental charm from that era.
You control Galivan, a space cop who explores alien planets screen by screen, clearing enemies to advance. Your main objective is to defeat bosses and recover crystals to power your ship. The sword attack has a noticeable wind-up, requiring precise timing, and you eventually gain a powerful mech transformation that changes your mobility and firepower. The pacing is deliberate, with some abrupt difficulty spikes in later stages. It feels like a game that demands patience and adaptation more than reflexes alone.
