Disclaimer: I don’t play single player
The “Biomes of Anerica” map (
https://www.warzone.com/Map/30404-Biomes-Americas) uses what’s called an INSS bonus system. Rather than all-or-none like most maps, bonuses give different amounts of armies for holding different numbers of territories. Be careful, sometimes bonus will give negative income.
You can see how much bonus you’ll get from the table in the top right. For example, *within a single red bonus* you’ll get 0 armies for having 1 territory, 1 army for having 2 territories, 2 armies for having 3 territories, and 4 armies for having 4 territories.
Note that if you have one red territory in each of two different red bonuses, you’ll get 0 + 0 = 0.
That’s really all there is to it. There are super bonuses for holding *all* territories if a color but these probably aren’t worth considering.
It will probably take a few rounds and many minutes to fully internalize how it works but it’s a really cool mode to play multiplayer games on as well!
