It allows for new game types!
The zombie add-ons should be canned for good. Seriously, that idea has run its course.
With all the hate this gets it was a cool addition to the game.
We can thank call of duty for making this such a hot item in the USA now
Renewing Interest : Just Add Zombies
This I agree with.
Depends from the type's. The one that is in the picture above yeah its worth it. The multiplayer mode PvP that was on RE5 i don't care for that one.
this is the only DLC type that's worth it.
This CAN'T be debated. Any DLC that adds new ways to play an already enjoyable game is always a good thing (maybe not with a few exceptions). It one of the biggest things, probably THE biggest thing, I look forward to the most when buying DLC, and it can be well worth the price tag if the content is strong enough.
