Those of you who have seen a Mercenaries 2 commercial might have the catchy "Oh No You Didn't" song stuck in your head. Well, in honor of the game being released today, it seems fitting to post the full song.

For the uninitiated: the song gives an overview of the "didn't get paid, now out for revenge" plot of the game. It's a bit of a genre-bender. Essentially, it's hip-hop vocals with piano accompaniment and a choir singing the refrain ("Oh no you didn't, oh no you didn't..."). You'll either completely despise it or you'll be humming it for the rest of the weekend.

The video below is a "Making Of" feature with the song playing in the background. You can also download the MP3 from the official Mercenaries 2 website. Mercenaries 2 hit stores today for PC, PS3, Xbox 360, and PS2.
