Burnout Paradise Remastered

D pad right > freeburn online > create match

wait for ONE player to join (if you have a friend for boosting, even better)

once two players are in the match

dpad right > freeburn games > cops and robbers

before you start the game I recommend turning the traffic off, and setting it to 1 round (saves a ton of time)
it will also allow you to manually switch from a cop to a robber depending on which achievement you are going for.

I just messaged the random in my lobby and they let me get two free wins, and I was able to unlock "the gang is back in town", "the right side of the law" and "golden" in about 5 minutes. Easy 60G.

These achievements are a bit straightforward, i'm just posting these guides incase someone was looking for a quicker way, or simply didnt know how to host a game of cops and robbers.
