So I was just playing the campaign mission ''Signal Lost'' on regular difficulty. And I must say it was a horrible experience. The AI was spotting me and engaging me through trees and bushes. So I had no idea where I was getting shot from. Another thing that happened was that I got spotted by an AI, he started shooting at me. I had no cover so I tried my best to shoot back. But he threw a smoke grenade 1 or 2 meters in front of him so I couldn't see him at all. I decided to move a bit to the right but he somehow kept tracking and shooting me. I eventually saw him as the smoke started to disappear and I killed him. But only one or two seconds later I was killed by another AI who was clearly out of my line of sight on the other side of a bush. This makes playing the campaign a really bad and un-immersive experience. And I cannot imagine how much worse this would be on the new jungle map Tanoa.
