The selection menu in Marvel Rivals is in the main lobby, where you pick your hero before a match. If you mean the game mode selection, that menu is on the play screen and lets you switch between quick match, competitive, custom game, and practice options.

Where to look

  • Hero selection: after entering a match or opening the lobby, the hero pick screen appears before you spawn.
  • Mode selection: click the play/mode area from the main menu to choose quick match, competitive, custom game, or practice.

If you meant something else

Some players use “selection menu” to mean the main menu hero display or the game mode menu. On the main menu, you can also change which hero appears on the load-up screen from your profile area.
