Sonic Blast is one of the Dirty Tricks the players can use in Mutant Football League. It is obtained by downloading the Demonic Legion Pack DLC along with the Cracksumskull Jugulars, Full Metal Mayhem and the Time Warp Dirty Trick.
This is a pass play. The QB chooses whichever receiver he wants to pass to. When the ball makes contact a sonic blast wave will erupt, knocking down all defenders in its radius. No defender will be able to intercept or deflect a Sonic Blast pass, which is used for quick scores.
