Black Ops map packs?

Do any of you think it's worth the money to buy the new map packs for black ops (360 version)? Honestly, it's like fifteen bucks and the maps are always terrible. The only thing worth playing is the zombie maps (I am an absolute zombie fan!!!)

If any of you ever want to play with me on XBL, my GT is Jaga HD (yes, a Thunder Katz reference)

I bought First Strike and I think it's pretty good, but I don't plan on buying any others.

I think first strike is the only good map pack so far. I'll probably get the new one coming out soon and I'll post here to say if it's good or not

I like both of the map packs and I am going to buy the new one coming out on the 28th. I actually didnt really like first strike but the Escalation map pack was really good, the zombies map was great and ive well overplayed the 4 multiplayer maps that came with it. Ive only seen a trailer on the annihilation map pack but it looks good so far. I would say if youre going to buy the map pack for 15 dollars and you dont want to play the online maps then you better play the hell out of the zombies map to get your moneys worth.
