EXPANSION PACK
CRITICAL MASS
Go nuclear.
A team race to the bomb. Build a Centrifuge, bank uranium, harden a silo, and prepare the heaviest missile in Salvo.
What it adds
Centrifuge
Build the team’s uranium plant. The whole war hears when your program starts.
Enriched uranium
Share one stockpile across the team. Protect the plant: losing it wipes the stockpile.
Nuclear silo
Upgrade an empty silo to hold a nuclear warhead. Keep your Fuel Depots standing so you can launch.
Nuclear warhead
Spend your materiel and the team’s uranium on a heavy strike. Assembly takes time, and the enemy can attack the buildings you need.
Break the chain
Use Recon to find the enemy’s program, then strike their plant, silos, or Fuel Depots before they can launch.
In the field
Choose your war’s rules
When you declare a standard war, switch each pack you own on or off. Everyone in that war plays with the enabled packs, whether or not they own them.
Pack choices stay fixed once you create the war. Field Day does not use DLC. Open DLC info from Account or Team before or during a war to read about each pack.
Salvo is in closed beta. TestFlight and internal builds include the available packs. The app shows the rules and numbers for your war.
