elite beat agents (survivor)

so i remember playing this game on the DS, and there was one level in the game were you have you help a peanut delivery guy fight of the these "kissing zombies" and they infect others buy kissing them. i could never beat the damn level but if you failed it the guy you were playing as is kissed and turned into a zombie

here is the gamne play and level but the guy playing is to good ande he dosent fail! but you can see how hard the level is....
im pretty sure if some one keeps looking theyll find a video of the guy failing the level

I didnt really see much of a kiss though.

It was the best I found. I'll keep looking though.
