Fencing - Epée (Mario & Sonic at the London 2012 Olympic Games for 3DS)
From the Super Mario Wiki
Fencing - Epée is a Contact Sports Event that appears in the Nintendo 3DS version of Mario & Sonic at the London 2012 Olympic Games. The aim of the event is to score points by touching the opponent with the epée.
In the game's story mode, Fencing - Epée appears as the second challenge of Sonic Episode 1, Sonic Arrives, in which Tails must beat a Fog Imposter of Luigi. It also appears as part of the fifth challenge of Heroes Episode 1, Mario and Sonic, in which Mario must beat a Fog Imposter of Sonic in it, alongside 100m and Judo. It also appears as the fourth challenge of Heroes Episode 7, The Promise to Toad, in which Tails must once again beat a Fog Imposter of Luigi.
In this event, the player must play two rounds, a semi-final round, which decides which round they will qualify for next, and either a final round if they win the semi-final or a third place match if they lose. In each round, the player must either score three points or have the most points when the time runs out to win. The player is able to advance by tilting their system away from them or moving the circle pad to the top right, and retreat by tilting their system towards them or moving the circle pad to the bottom right. To score a point, the player must touch their opponent with the epée by pressing the A button to thrust. Thrusting when they are not close enough to the opponent will cause them to lose their balance and are briefly unable to perform any moves. If they thrust at the same time as the opponent, their epées will clash and neither character will score a point. Once a point has been scored, both characters will return to their starting positions in the centre. Omochao acts as a referee in this event.
1) Advance: Tilt the system away.
