Hello.
I thought about seeing gaming of other people.
So you can see a poor view about a person gaming and if you click on it , person’s mission’s information and a button for see gaming will visible:
Oh I forgot say this.
If player explosions and you aren’t see fighting you see player’s explosion.
And if player game overs enemies will back to planet and player will come back.
Just like school fights and the other students screams FIGHT FIGHT!
P.S. If the multiplayer comes, there can be a option which you can go and help to your friend in the mission, like old games by pressing F2 to help your friend.
