In my current world I too have a interesting river spawn.

I spawned on the shelter and got the antibiotics mission. I looted the town and found some but also decided to drive around on a motorcycle and found a lab. Got in and ended up mutating via clone bodyparts/mutagen and came out with canine sense of smell, high night vision, a tail and badly deformed. A net positive I would say.
I don’t make it back in time for the antibiotics because of the swamp crossings at every point. So far after playing lightly this is my first guy who’s passed early game.
To me early game is a good mix of weapons, a closed vehicle and some skills leveled pretty well.
After that it’s being sustainable. I hear beehives are good for training dodge and early food but I haven’t messed with them yet.
Also how to rollmats work? I tried using one and sleeping on it but it didnt work. It said I unrolled it and placed it on the ground but nothing was there and my character would not sleep on the square.
