The Bowling Minigame is a hidden minigame available in two-player mode in Primal Rage.
How to Unlock[]
In order to play this minigame both players must pick Armadon and execute his Spinning Death move simultaneously three times in a row. If done correctly the word "BOWLING!" will flash below the lifebars, while the two players move to the right of the screen and a group of Worshippers position themselves on the left, acting as the bowling pins.
The minigame works in a best of two format, with each player having two chances on their respective turns. At the end each player's score will be summed up, with the one with the highest scored being declared winner, after which the regular fight resumes.
