There are 2 options to get this achievement. You can play any online mode, or you can play hotseat, which is offline, 2+ player alternate shot mode. For the purposes of this guide, I'm going to show you the quickest way to get this achievement since your performance doesn't matter.
You need to play a full 18 hole HOTSEAT game for this to unlock. To set one up....
* Choose OFFLINE from the main menu (means there's no waiting for others to take shots)
* Choose "COURSE: ANY" (I chose forest)
* Choose "MODE: ANY" (not sure if a custom game voids this achievement).
to add a second player (you do not need a second controller for this).
to start the game
* When ready to take your first shot, press
and choose "FORFEIT HOLE" (this will instantly end the hole).
* Repeat for all 18 holes
Should take 5-10 minutes for this achievement this way.
