I started by playing the exploration setting until I could get a feel for the game on PS4. After clearing most of the outposts, I thought I would try survival mode. Wow... to say it is challenging implies that there is a level of impact the player can have on their survival. First, no matter how many times I shot a deer or cut down a tree, my survivors wouldn't' go harvest anything unless I had collected every scrap I had to leave behind because of a lack of inventory space. I could see the area appeared to be harvestable, but there was a little red dot next to the icon... so I would have to stop my progress to pick everything up, drop it back off at camp, then try to set out again. And it seems that the minute I would leave my outpost, everybody would stop hunting and gathering for themselves, even though there were spots nearby.
I finally got fed up after being killed 3x in the same location while trying to cleanse the third outpost. One follower was crushed twice by falling cars and had to be revived, then there was a blizzard on top of a blizzard (and I was killed literally 2 steps away from a shelter). At the outpost after my 4th or 5th attempt, I was crushed again by falling vehicles after the eclipse had been pummeling me for what seemed like forever and (I thought) had gone away. The only way to clear outposts in survival mode is to progress very slowly-- stopping every minute or two to warm up or running around in circles trying to avoid the eclipse...but if you progress slowly, your camp gets attacked, and your followers freeze and starve to death. There needs to be a balance. I'm glad I saved my earlier game because I was interested in the story line, Getting a few trophies isn't worth the frustration of a system that sets you up to fail.
