Quickstart
How to actually play this with friends — written by Claude.## Set it up - Install via Steam; host a campaign or sandbox sub from the main menu — vanilla already supports a 16-player crew - Browse the Steam Workshop for submarine blueprints and role-packs before you pick a sub; the stock subs are fine but community blueprints add real variety - Assign jobs at character creation: captain, engineer, medic, security officer, mechanic — every role has real systems to manage, not flavor text
## Your first session - Run an early campaign mission or a short sandbox dive first; reactor management and hull breaches punish a crew that doesn't know the basics yet - Security should actually watch the airlocks, Engineer should actually monitor the reactor — don't let everyone cluster in one room "just in case" - The ship fails in cascading ways: a flooded room kills power, dead power kills life support. Fix small leaks immediately, don't wait
## Group size advice - Scales genuinely well from a tense 2-person sub to a sprawling 16-person crew with dedicated specialists for everything - 4-6 is the sweet spot — enough roles to matter without three people fighting over the one medic slot - One of the deepest friend-slop picks on Steam; budget for a standing weekly session, not a one-off
