Well, I recently got Annihilation, here are my thoughts:
- Hazard > Hangar 18 > Silo >>>>>>>>>>>> Drive-In
- Hazard and Hangar 18 are great. No real complaints, except for the fact that there's a lot of snipers on Hazard. A LOT.
- Silo is big, but not Derail/Seelow/Fuel big. It really doesn't seem much bigger than Hazard to me. It's not that big of a deal. I like it.
- Drive-In SUCKS. Nothing but flank routes and bad spawns. I also find it hard to distinguish between people and things at times because of the color scheme. It's horrendous.
- Shangri-La is a fun zombie map, but I'm still trying to understand it. First try got to round 17.
Overall, this is the best MP in any Call of Duty to date, in my opinion. Lots of good maps, one bad one that is really only bad because I think so, and I probably haven't gotten used to it yet. It seems as if most of these maps have a wide open center that's basically instant death if you go into the middle of the map (Drive-In, Hazard, Silo), but I doubt I'll be deleting this map pack, I really enjoy it.
