Mid strength regions generate Troop Ambushes.

Low strength regions generate things like Jailbreaks, High Value Prisoners, and the various data raids. The result being that it'll be more expensive to expand if you don't try and get some free Radio Towers along the way.ĭefinitely do not liberate all, or even most, of your contacted regions.ĪDVENT controlled regions are very valuable. In 1.3, that theory may change as winning the Tower mission in each region gives you a free Radio Tower and purchased Radio Towers will be much more expensive. While it's possible to win the game with only 1 region liberated, it's more common to aim for 3 regions liberated for the steady supply income and then liberate other regions if it is strategically convenient. As you liberate each region you should be opening at least one new region to replace it. In general, 3 contacted regions is sufficient to provide more than enough missions in the early game. Aside from getting bonus contacts, that's the limit on regions you can contact without the radio room in the avenger. From there, you can liberate 1 or 2 regions over a couple months, allowing you to increase your contacts and expand towards the Blacksite (which will now be visible). A common strategy is to expand to 3 regions relatively quickly, while attempting liberation missions as they appear.
