how do side quests work, is it clear when / where you get them, or do you have to comb the maps to find them?
I just got into the open world for the first time, and insted of going to the mission objective im just walking around finding things, or trying to, mostly just killing robots attacking the data points, but it feels like im wasting my time and should just go to where the mission told me to go.
I would suggest unlocking fast travel first, so as to not burn yourself out on the sidequests. As for finding them, they are marked as dark red dots on your map.
