You unlock Weapons, Prefab Mods and other Stuff for the Daybreak DLC and Main Game while playing the DLC
First you unlock Stuff for the Daybreak DLC and bit by bit for the Main Game.
At first you get a Supply after Wave 3,5 and for the Victory ( last Wave 7 )
As you playing you noticed that you only get a supply after Wave 5 and 7, Wave 3 gives you
50 Prestige Bonus.
Later at the End you only get a Supply after a Victory (last Wave 7),Wave 3 gives you 50 and Wave 5 75 Prestige Bonus
Thats means you have to play this a very long time and you need later on everytime a Victory to unlock all 4 different Red Talon Facility Prefab Mods
When you have all four unlocked for the Main Game you will first need a Base that allows you enough Space( small indoor and small outdoor Slots) to build it.
like this in Meagher Valley
Base: Squelones Brewing Companyhttps://www.primagames.com/media/files/all-bases-state-of-de...
Then you have to call the Daybreak Trader by phone and buy all 4 different Prefab Mods, you need 8K Prestige Points to buy them all.
Go back to your base and Build it
