This is the first majorBack 4 BloodDLC expansion since its launch last October. And the nice part is, as long as one person in a party owns theTunnels of Terror, everyone in the party can play the content.
While it’s the first major expansion content, Turtle Rock hasbeen keeping up with free updatesforBack 4 Bloodas well. An update in December addressed offline campaign progression, difficulty, and more. (Those who want a little more difficulty will get that alongsideTunnels of Terrortoo, when a free update adds the No Hope difficulty.)
Back 4 Bloodwasa pretty good timefor some co-op zombie slaying last year, and filled a bit of a gap when other big co-op games didn’t have a way to play PvE out yet. It’s a really stacked spring, but it might be worth it to find a night to do some co-op runs of these new dungeons when April rolls around.
