Back Attack is a 4-player minigame in Wii Party. The concept of this minigame is similar to Bump the Dump from Wii Party 2007.
The camera zooms in on the fourth player, who shoots a Mii in a white car that is in front of them. The camera then zooms out to show the whole field and all the players.
The objective is to be the last player remaining by not getting the back of the vehicle shot. Players can only move along the track and can only turn at intersections. Players can not do 180 degree turns. Occasionally, a speed powerup will appear, which causes the vehicle to flash and lets the user move more quickly temporarily. Getting hit anywhere other then the back has no effect, though getting hit in the back causes the vehicle to fly up and out of the arena. The winner is the last player remaining, or any players remaining after 60 seconds.
The camera centers on the victor, who turns toward it and waves.
