Quick Overview
Payday 2 is a first-person shooter about a criminal gang, and it is the sequel to Payday the Heist. It does have DLC, but it is not required for the platinum. Though it might make it easier as it gives you frag grenades and a couple heists that have a chance for certain escapes. This is the PS3 version which is a very outdated version of the game. If you want a more up to date version, you can get Payday 2 Crimewave or The Big Score on PS4.

Online/Offline Trophies
Most trophies can be done solo but there are a few that will, require online coop. Playing solo offline will allow you restart a heist as needed (ex. Getting 9 paintings will take multiple restarts). It is possible to join mid heist, so setting up certain trophies then inviting others to join is possible.
