Zillion II - The Tri Formation
Zillion II - The Tri Formation is a side-scrolling action game developed by SEGA in 1987 for the Sega Master System. Players control one of three characters, each with distinct weapon types and abilities, which can be switched between levels or at certain checkpoints. The game features run-and-gun platforming action where players navigate through military-themed stages filled with enemy soldiers and obstacles. Armed with various firearms ranging from standard rifles to flamethrowers, players must shoot through enemies and solve simple environmental puzzles to progress. The campaign spans multiple stages with increasing difficulty, requiring precision timing for jumps and combat encounters. Controls are straightforward: directional pad for movement and buttons for jumping and firing. The tri-formation system adds strategic depth, as selecting the right character for each stage's challenges becomes key to success.
