Requires you to score 5000+ in Whack-a-Cactuar. This minigame is first played in the intervention quest "The Five Cogna Lords: Tometown, Part I" during Chapter 21. Minigames can be replayed at any time either by repeating the intervention quest or accessing the minigames menu of the console in the Twins' Bedroom at Nine Wood Hills. Playing it via the Twins' Bedroom is advised as there is no dialogue or fights to skip through.
Controls/Rules:
You start with three lives;
Missing a cactuar will cost you one life;
You have one minute and thirty seconds to play;
Running out of time or lives will end the minigame;
Point the Left Stick in any direction and press X/'Square' to kick;
Point the Left Stick in any direction and press O/'Triangle' to punch.
Tips and Tricks:
Punching seems quicker;
If the train conductor appears prioritise hitting him as he gives +10 seconds to your timer, if you miss or hit any other cactuar first he will disappear;
You have enough time to safely hit three cactuars before they disappear up until the 30 second mark, after that drop to two;
Gigantuars give the most points and you will need a few of these in your run in order to get the required score.
