So in the final cutscene of danger rising it shows that the agency’s project illapa is in the eastern US. However, there has been a lot of controversy from having games set in real places (ex: Bolivia complaining about GR wildlands). A good idea I had to avoid this was to have the prologue mission be set at this agency base, you destroy the base then get intel about an island that the agency has took over( won’t belong to US) and then you got there and get released into the open world
