It's tough playing solo. I place portals as I go so I don't have to walk ALL the way back. You need a second set of maxed out armor and weapons to get your body back. The mist is too extreme. i wandered around a large Mistlands area for several hours and only found one Infested Mine. Is that because I couldn't see or because there is only one in the entire area? I don't know, but it wasn't fun and I could not make progress for several hours because I could not find the mines. This is a test mode, so it can change, but in its current state, Mistlands is more grind than fun. Maybe that will change when I get more cores, but how long will that take?? Good luck!
