Nintendo and GAME are set to join forces this Saturday (April 20th) and launch Multiplayer Mayhem. An event that will take place across 15 game stores across the UK. 

3DS owners are urged to bring their beloved handhelds to participating stores and take part in 'unique multiplayer tournaments', try new unreleased games and grab some Nintendo goodie bags. 

Not only will you be able to take part in some multiplayer shenanigans but you'll also be able to go hands on with LEGO CITY Undercover: The Chase Begins a whole six days before its official launch on April 26th. 

The unique multiplayer challenges and competitions on offer are as follows:

Monster Hunter 3 Ultimate – Team up with three other players to track and hunt ferocious monsters in this epic action RPG.

Luigi's Mansion 2 – Finally stepping out of his brother's shadow, Luigi takes centre stage in this spooktacular adventure. Up to four players will be challenged to head up the Thrill Tower sucking up ghosts as they go.

Gamers will also be able to take part in demos of the latest Nintendo 3DS games, including Fire Emblem: Awakening. Those new to the franchise will be able to get one to one trials to help them get the most out of this unique game while Fire Emblem fans will be able to team up and get hands on with the 'Double Duel' mode. Castlevania: Lords Of Shadow - Mirror Of Fate will also be available for fans of the classic Konami action franchise as well as Nintendo eShop titles Splash or Crash and HarmoKnight.
