This is a tightly designed and cohesive adventure site, and though it falls somewhat outside the traditional Appendix N sword-and-sorcery/pulp aesthetic, it still has a strong sense of atmosphere. The Encounter Deck and Security Lock mechanics are clever, but I wonder if they’re a bit more complex than needed. Functionally, the encounter draws could be approximated with a d4 for type and a d10 for result (with some allowance for duplicates), and the math behind the lock mechanic boils down to a 1-in-6 chance of success if I read it correctly. A doofus like me prefers the least amount of prep possible.
Placing the core's restart behind a system that can permanently lock out the party feels potentially too punishing. A remote reset option (perhaps in a central security room) for fused locks would allow the party additional attempts at the expense of time/risk of encounters.
The layout, on the other hand, is a standout: stylized, full of character, and efficiently packed. Very little space feels wasted. Good work on this.
