Play Choujin Ookami Senki - Warwolf (Japan) Online

Choujin Ookami Senki, known as Warwolf in Japan, came out for the Nintendo Entertainment System in 1990, developed by Takara. It was one of those late-era NES games that tried to push the hardware a bit further, with a sci-fi theme that stood out among the platformers and RPGs common at the time.

You pilot a transforming mech, switching between a ground robot and a flying jet to navigate levels and fight enemies. The main goal is to advance through side-scrolling stages, destroying enemy forces and avoiding dense patterns of enemy fire. Signature mechanics include mid-stage transformation to adapt to threats, screen-filling boss encounters, and a limited but rechargeable weapon energy system. The pacing is intense, with difficulty that demands quick reflexes and careful resource management. It feels like a constant, hectic dance between evasion and aggression.
