Main Base (First Map) - where is the second upgrade to find??

[IceFoxx]

I looked and googled but there seems to be only one upgrade in the first map, called main base. But in the Main Game Menu it shows "Upgrades 1 of 2" so there must be another one, but no one knows where?

There isn't a second upgrade, the one zone you've found should've given you both. Game can be dodgy about counting them right though.

Found the solution now. There is a second upgrade, its a Sticker you get when you solve the side mission "beautiful view"
