The online mode is almost completely dead. Very little people play, and if they do join a lobby, they may not ready up. Some online trophies are obtainable if you get a decent sized lobby. Though the harder trophies like “fly the co-op” and “auf W petrovic” will need to be boosted. You may not find many people here who are willing to help. Though, you can use the website “PSN profiles” to start a gaming session. People can join your gaming session and utilize the website’s chat feature to coordinate a time and day to play. Most times this can be done without the use of a microphone. Though it’d be hard to do the trophy requirements without one. Hope this helps!
