I enjoyed the beta this weekend. Most of my game time was with a friend and we both enjoyed the great tactical approach to the game. Never got a chance to use the AI ghosts so have no opinion on that. I have seen a few people talk about not being able to move dead bodies I agree with this as while in a mission I was sneaking round a corner where an enemy popped round. I stealth killed him but the body was out in the open of the base courtyard it would of been handy to move him away out of sight. He then disappeared.
Other issues are I feel the climbing feature could be improved. Most rock faces and walls you can climb but I was running up a mountain to then think I could climb up a small rock face. I could only climb the first part then there were no more actions available to climb, so I had to go a different route.
The overall experience was brilliant and I look forward to playing the entire map.
I also remember that some unlocks didn't move over when I joined a friend. He had the mortar unlocked but when I joined his game it wasn't there. I hope this isn't a thing that will be in final game. If they keep it like how the division played out, with what you have unlocked carried over to any session you joined.
