All but one of the multiplayer trophies in Ghosts is based around playing the default Extinction map, the other trophy requires you to play Safeguard. I call them multiplayer trophies but you can in fact, complete some of them in solo matches, so if that’s easier for you to do, then go for it. Extinction mode actually scales with the number of players in the match, so it might be better to play solo, instead of struggling with public players who can’t take care of themselves. I managed to complete all the multiplayer trophies when Ghosts first launched but with all the patches and updates to Extinction mode, I think it’s actually a fair bit easier now. On the whole, I’d say these multiplayer trophies aren’t too bad, there’s a couple annoying ones that require you to go out of your way but nothing outrageously unreasonable. Despite there being more SP trophies, I reckon you’ll be spending a little bit longer working on the MP ones because Extinction matches can take a bit of time to complete and you’ve got to do it several times.

No Man Left - Escape with all four players in Regular or Hardcore difficulty.
Exactly what it says on the tin, you need to start with a full lobby and everyone has to be on the chopper before it takes off. I managed to get this done a couple weeks after Ghosts first came out, when lots of people were still getting to grips with Extinction, I’m not sure how populated the servers are these days but there should still be enough people playing.
