 Another game mode included in Backbreaker is the mini @-@ game " Tackle Alley " . In this game , the player controls a running back who starts in their own endzone . The player then attempts to score a touchdown by running up the field and evading a wave of defenders to score points . Special moves such as jukes and spins create a " combo chain " , which multiply the player 's score by an amount depending on the length of the combo chain . After a player scores , they advance to the next wave of defenders and must repeat the process . If a player is tackled before reaching the endzone , they must start over the wave and lose a " life " . The game ends when all of the player 's lives are depleted or the player passes all 100 of the waves , which become harder as the mode progresses . According to NaturalMotion , only 0 @.@ 88 percent of all Backbreaker players have managed to clear all 100 levels of " Tackle Alley " . Game producer Rob Donald states that the mini @-@ game was meant to add an arcade feel to the game . " It was meant to be a complete diversion from the more realistic main game , a complete arcade challenge ... Everything about it was meant to replicate the pressure and the frustration of playing a cabinet that you know is stacked against you , " said Donald in an interview .
