Play Gamera - Daikaijuu Kuuchuu Kessen (Japan) Online

Gamera: Daikaijuu Kuuchuu Kessen came out on the Game Boy in 1990, developed by Towa Chiki. It was one of those early handheld games that tried to capture the feel of a monster movie, back when portable screens were small and simple. You don't see many kaiju games from that era, so it stood out just by being what it was.

You control Gamera, flying from screen to screen in a side-scrolling shooter format. Your main goal is to defeat other giant monsters, like Gyaos, by shooting fireballs and ramming into them. The game uses a life bar system for both you and the enemies, and you have to dodge projectiles while managing your own attacks. It's not an easy game; the action is fast and the screen can get crowded. Playing it feels like being in a miniature, frantic monster brawl.
