I've been playing on the 360 using the classic pack, and my friend gave me his unwanted mercenary pack code. I'm just making sure before I try to redeem it that this will actually work. Has anybody else been playing on the 360 with more than one of the packs installed?

I ended up with 2 - the classic and tribal packs. Used both and both worked fine, and I'm on the 360 too

Ok, thanks for the help

Yes, if the code hasn't already been used.
