Heavy Unit

If you’re looking for a hidden gem that showcases the PC Engine’s ability to pull off massive, screen-filling sprites, Heavy Unit is your game. Originally a 1988 Taito arcade brawler, this 1989 HuCard port is a blast to play because of its unique transformation mechanic—one second you’re a sleek starfighter, and the next, you’re a hulking, heavily armed mech. It’s got that quintessential late-80s sci-fi grit, with organic-looking alien bosses and tight corridor navigation that’ll test your reflexes. While it might fly under the radar compared to big names like R-Type, its tactical variety and distinct "mech-meets-shmup" vibe make it a standout for anyone wanting to see what the PC Engine could really do.
