Ok Well idk if anybody Has this game but i was way to lazy to play 10 rounds of versus. (and win)
Not to Mention i don't have xbox live so my only way of winning it was playing against a friend and yeh id win one round and then he wouldnt wanna play no more...
So i have found a Not so Simple Solution to this, it's a lot shorter then playing and winning 10 whole campaigns of versus thats for sure.
SOLUTION: Go On Versus (With a friend) go on "Edit Game Settings" Change the chapter to any Last Rescue Chapter. (I Suggest Dark Carnival 4 an Easier way to get Achievements) Anyway When your on the last Chapter You Only have to Win that One Chapter to get a Win for the (Bull Shifters Shirt Award)
P.S. Idk If this Works In Campaigns for Getting the Med-kit.
