Secret Smash is a co-op event match in Super Smash Bros. for Wii U. In it, player 1 controls Duck Hunt and player 2 controls Mr. Game & Watch and must defeat another Duck Hunt and Mr. Game & Watch in a stock battle on the Gamer stage. The players have 1 stock while the opponents have 2. If either player dies, the event results in a failure. 5-Volt must be avoided at all costs since she can deal extremely high damage and knockback and can possibly OHKO.

Progression

Completing the event on the hard difficulty setting awards the player with the Springer Collar equipment.

This event is unlocked by clearing Flat Fracas and unlocking Duck Hunt. Completing the event does not unlock any further paths.
