Who Needs Friends?
Played 20 Matches of Deathmatch
How to unlock Who Needs Friends?
To get this trophy more quickly, go: Play Game => Choose Playlist, then untick every box except the one that says "Deathmatch". Now press to initiate a search with your custom filters. If you manage to find a decently active server, use it to your advantage and stick with it until the trophy pops. If the search fails to find a server, either come back later or invite a friend to help you out.
"Deathmatch" does exactly what it says on the tin so kill the other players before someone kills you. It doesn't matter if you win or lose, the trophy will pop after you have played 20 matches of Deathmatch.
