Play Zillion II - The Tri Formation Online
Pick JJ, Apple, or Champ—each handles totally different, and you’ll keep swapping mid-fight when certain enemies laugh off your shots. Lose a teammate and suddenly everything hits weaker, turning shootouts into desperate scrambles to survive.

Zillion II: The Tri Formation came out for the Sega Master System in 1987, developed and published by Sega. It was one of those late 80s action platformers that tried to blend run and gun gameplay with a bit of exploration, standing out with its team based mechanics at a time when single character adventures were more common.
You control a team of three freedom fighters, JJ, Apple, and Champ, each with unique weapons and movement styles. The goal is to infiltrate an enemy base, rescue captured allies, and destroy the core. Key mechanics include switching characters on the fly to exploit enemy weaknesses, navigating multi screen rooms that require careful platforming, and managing your team's health since losing a member reduces your firepower. The pacing is tense, with enemy placements that demand quick reactions and smart character swaps. It feels like a careful, tactical action game where every mistake costs you options.
