About System Crash Underworld
System Crash Underworld is an add-on that introduces a story campaign and a card set built around using your Archive, the discard pile, as a resource. Its campaign contains 30 new missions, and the set adds 20 cards to collect.
Build around your Archive
Some Agents and Support cards grow stronger as you discard more cards. Events can bring cards from your Archive back into play, adding new options for building your deck.
Burn cards for power
Underworld cards can deal large bursts of damage, but their effects require you to burn cards from your own deck. Using these combos well can sweep opponents off the board; using them poorly can leave your deck depleted and you weakened and exposed.
