Highlights

A deep sea submarine spy TTRPG adventure for 321RPG. 60-page zine, PDF included.

In Minisub Mania, your mission is clear: infiltrate the top-secret undersea base, Oceanus, rescue your captured leader, Shark, and escape with vital intel.

As elite pilots of agile, high-tech minisubs, you’ll dive into the depths, using stealth and skill to complete your mission. Your subs are built for espionage, sabotage, and deep-sea exploration—but survival won’t come easy.

Getting in is simple. Getting out means navigating perilous underwater caves, evading enemy subs, and combating the deadly creatures lurking in the deep. Are you ready for the challenge?
