Game Play Question

I have watched a few videos and looked at several threads now, one aspect I am curious about is this: When you are playing and travel to the Ark to spend currency earned on upgrades and buying equipment when you go back to the zones again can you revisit previously entered zones and if so do the enemies and loot respawn in those zones because I noticed on several of the video’s I watched that they had level requirements either required or recommended for entering them.

You can revisit previous zones as much as you want. We recommend it to find loot, scrap or weapon parts you may not have found previously. Enemies won’t respawn, though.
