## What is Core Containment?

Hold the line. Seal the reactor.

New Orange City is under siege. Mechanate drone-cores ricochet through the reactor decks beneath the city, and you are the one sealing them in. Drag across the deck to raise a containment field. If the field finishes, it seals; any space with no core inside is claimed. Claim enough of the deck to secure it and continue to the next one. If a core touches your field while it is still growing, it shatters.

A SIMPLE MOVE THAT KEEPS DEEPENING
- Crawlers that chew through sealed walls, spiders that walk across your claimed ground, tethered pairs whose link shatters fields, and shards that slip through thin walls
- God-Emperor Deblon, who scorches the deck from above and learns new attacks the deeper you go
- The Foreman, a repair construct that pries your walls loose until you seal it away
- Deck conditions: tremors, brownouts, swarms and more
- Infestation decks that throw one kind of core at you, and nothing else
- Supplies to grab mid-deck: shields, freezes, gravity wells, fortified plating, and a few rarer ones deep down
