Hey Gamers! Welcome to NHL 19 World of CHEL!
Video guide below if you prefer video!
This is once again a VERY easy achievement in NHL 19 (plenty of them in this game) that simply requires you to play a game of Drop-in Threes.
Of note, this is not referring to the NHL Threes mode in the main menu, but this is a game mode available within the new World of CHEL portion of NHL 19. Simply select Drop-in Threes once you are in the World of CHEL play menu and finish 1 game to unlock this 15 Gamerscore.
