All of the Conker MP achievements are simple, but here are some guidelines for those curious.
- It doesn't matter if you win or lose, but it will not work if you start and quit a game.
- A second player or controller is not required.
- For a quick win/lose simply go into set-up and change the score limit to 1.
- For Raptor specifically choose caveman and you can just stand at the spawn point and wait for a raptor to come kill you, or jump into the nearby firepit.
