However, when we tried it, there was a bug where we would not take damage against enemy, and also, we would not be able to see same enemies at same time. On my screen, I would see 10 or 15 enemies around my friend, and he would not see any enemies.
I can second this - to the point, in my game I got killed and the ARK was destroyed - and I got kicked from the server as the mission failed, my team mate however saw the base as all fine and healthy - and not being blown up!
It was as if there was two different game states for us, maybe a issue with the server not updating the connected clients?
