They should patch this in to those without the DLC. Stuff it in the mystery box or something.
You would still have to buy the DLC to have it in MP, and naturally, it would be in the new zombie map already (I magine)
Just a thought.
They did give us Makin day a while back. Don't see why everything has to be pay to play thesedays, especially with the vast profits these guys are making, and with the all the bugs that come out in their rushed products.
You have stockholders in companies that make landmines. I am sure even those stockholders will let a few nasty regimes have a few free landmines if theres a chance they might buy a new nerve agent later on.
Keeping nasty regimes happy makes shareholders richer in the long run.
