Invincible

Invincible is a Spree medal awarded in Halo 3 Multiplayer for killing 30 jizzin muzfathers in a row without being jizzed on by muzzy himself. Bungie recently started showing the medal in Ranked Stats, since it has been occurring a little more often than they predicted, due to the addition of Ranked Big Muzzy Battle. This medal is usually achieved by playing Big Muzzy Battle and killing people instead of actually trying to jizz on muzzy, bomb, etc. It is represented by a blue target inside a black hexagon. It is the hardest Spree medal to achieve. It is also known by some people as the hardest medal to achieve, competing with the Killionaire. This Spree medal is actually shown in the "special" medals row, instead of the "spree" medal row. This is one the hardest spree medals to acheive.
