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 A CITY A HUNDRED DECKS DEEP Decks have their own names and layouts, and the music slows and darkens as you descend. Earn a seal rating on every deck, chase PERFECT seals, and see if you can reach the bottom. PLAY EVERY DAY The Daily Deck is the same deck for everyone that day.
