In one of COD Black Ops' new Wager Match modes, Gun Game gives you a new gun for every kill. Here is a compilation of Tina Sanchez working through twelve tiers of guns. Edited by Thierry "Scooter" Nguyen, so blame him if you don't like the actual video editing.
Sticks & Stones Mode:
In Call of Duty: Black Ops, there are various Wager Matches that you can play to gamble your Call of Duty Points with. Sticks And Stones limits you to just a crossbow, some ballistic knives, and a tomahawk. Community Manager Tina Sanchez does "just okay" in this mode. Tease her about now using the tomahawk!
