With game companies scrambling to secure rights of top flight celebrities (and John Madden) for voiceovers, cameo appearances, and other marginally related uses of their fame, some of the most memorable contributions in gamedom have come from the anonymous dudes with vocal 'tudes. We've sifted through all the mouth pollution and pulled out our favorites:

Halo series

Memorable Lines:
Double Kill. Overkill. Killtrocity. Killimanjaro. Killionaire!


Mortal Kombat series

Memorable Lines:
Finish Him/Her! Fatality!


NBA Jam


Memorable Lines: Whoaaaaaaa KA-boom! Rejected! From downtown! Nails it! He's on fire!


And, our personal favorite: GUGLIOTTA!
 


Gauntlet

Memorable Lines: Treasure, 100 points. Remember, don't shoot the food. Save keys to open doors. Save potions for later use. Warrior, your life force is running out. Wizard needs food badly. That was a heroic effort.

"A formidable opponent awaits. K.O. Victory belongs to the last one standing. You win!"
