Settings in the game-edit the list, you can search directly. The ID name is pandahero, and the list should be viper, so that's all.

In the quick game, please press the "3" key on the keyboard (above the letter keypad) or the Y key on the handle in the team selection interface, then press the direction key to select the viper roster and confirm with the space bar.

If you want to use MG or ML viper list, please make sure that the "custom lineup" option at the bottom is turned on when opening the file, and then you will enter the list selection interface. Press the arrow keys to select the corresponding list, and then confirm with spaces.
