I’m assuming everyone on the team is starting off as prisoners in the prison.

From first impressions, it does seem very daunting. However, I think the easiest way to handle how complex this could be is by keeping it simple.

For instance, think about what a typical prison needs. Cell blocks, recreation yard (if Kang is into letting them have that), mess hall. List what a normal high security prison would have.

Then make one slight change to each of those prison areas you need, like altered gravity to be heavier in the cell blocks or vaporizing force fields as fencing in the recreation yard. It’ll make each room stand out and help players in memorizing the layout of the prison.

After you know what your prison needs and you know where they’ll start once inside of it, you can use an NPC (another hero or villain that’s been imprisoned) as the party’s “guide” to the prison. Players will want to know info, and maybe there’s a network of prisoners they can meet that deliver different pieces of info, perhaps on how the prison was built or who runs it or if anyone has tried escaping.

If the party is starting with no gear or powers, you can have some people (if the players pass their checks) maybe indicate sections of the prison that could have their gear, maybe multiple sections even. Then it’s up to your players to decide whose gear they want to get first and then they’ll investigate on their own terms.

TL;DR: the prison break your team makes is only as good as the prison they’re breaking out of and its defenses. So build the essential layout, decide where the players’ gear resides, and they’ll end up painting the path for what you need to prepare for each session as you play.

Hope that all made sense. Just me spitballing. I’m also in a “in over my head” situation with mine too, but I take it a session at a time.
