oh so you get 500 for the achievement without needing to complete the whole set? may need to do that thenOh, interesting.
You know the State of Decay 2 Punch Card?
There's 3 500pt challenges on it. 1 for a specific set of achievements, 1 for renting a zombie movie, and the third for completing the first two.
After activating the card, ANY achievement in the game activates the 500pts for the 'specific' set. Just FYI.
