Heavy Unit is the 1989 PC Engine port of Taito’s arcade horizontal shoot ’em up, where you pilot a transforming starfighter‑mech to defend the Le Tau colony from mutant alien creatures. It’s a tougher, old‑school shooter with mecha transformations and chunky late‑80s sprite work, making this Japanese HuCard a solid pick for PC Engine shmup collectors who want something a bit more obscure than the usual Hudson fare. Free tracked shipping, well packed for collectors
