Not the best map pack but not the worst.
Drive in:
If you liked how small nuketown was then you might like this map. It has a nice mix of sniper sights and places for smg gunners to run down and gun down enemy's. Though it may be somewhat difficult to run a shotgun, you should still do fine in this map. Personally this is my favorite map since you can practically use any kind of gun here and do well in the game.
Silo:
Supposedly this is suppose to be much larger then array, but when your playing silo it feels more of like a medium map comparable to villa. It just seems it just isnt open enough. Even though it is a big map there are sniper points but you will get killed EASILY on your way there. I would say this would be a better map for assault rifles and smg gunners. There are plenty of corridors to get you in some close combat situations getting you some easy kills. Its an ok map nothing to special or stunning.
Hazard:
If you played waw you can tell treyarch remade cliffside and turned it into a golf course called hazard. Even though it is a remake treyarch did tell you in the announcement trailer that this is a remade map. If you haven't played cliffside before you can tell right off the bat its a sniper map. There is a huge gap right in the middle but there are two corridors on each side which can get you straight to the edge of the maps. There you can pick off snipers with ease. I wouldn't encourage using a shotgun in this map due to the long corridors and lack of tight spaces. Now lets talk graphically since this is a remade map, it should have better graphics. I have to say it looks absolutely gorgeous. A very bright and cheery golf course setting with the beautiful striking colors really is a break from the normal drab colors you find with most maps. The best graphically appealing map out of all the maps in the map pack.
Hangar 18:
The map supposedly is chock full of easter eggs and right of the bat you can tell when you spawn in a room with a Floating Apple (If you dont get the joke, search it on youtube) But other then that it is the worst map out of all of them. The map is somewhat open yet there is nowhere to snipe. Difficult for an smg or a shotgun to go on a killstreak. I feel you could only use an assault rifle or an lmg in that map. Even then I find the map to be frustrating. Every map they have a just truly awful map and well, here it is.
Shangri La:
Ive never really felt there was a bad zombie map in the series (excluding call of the dead) and this is no exception. This map would have been great but there are some things that detract from this map and can make it somewhat annoying. "Special Zombies" are in the another zombie map and here are the 3
1. Napalm Zombie:
Cant be killed unless you touch him or get a nuke. And when you touch him he explodes and guts you off of an area due to his napalm explosion.
2. Power drop monkeys:
They steal your power drops unless you kill them, if you do they randomize the power drop and you get a new kind of power drop. Now this wouldn't be as bad in a regular map, but on shangri la there are traps that only effect you like quick sand and spike traps, but not the zombies. So its hard to kill these critters if you get stuck in quicksand or stuck in a spike trap.
3. Screechers:
The least annoying out of all 3, but what it does is screech at you and blur up your vision and somewhat tampers with your mobility. Fortunately you can kill this zombie easily, but if he catches you in the wrong corner in the wrong time, you can easily get an unfair death.
Fortunately there are things that really do add to this map. The spikemores are one of them. Claymores with sharpened bamboo spikes duck taped onto them. When triggered sends an explosion and a series of spikes killing much more zombies then a regular claymore would. Monkey bombs are back which is very nice to see, especially if your downed. The new wonder weapon the shrink gun is good but not great since it only shrinks the zombies for a second or two so you have to use this gun at close range.
Otherwise this is a pretty good map pack, it didnt receive a higher score probably because of
1. The price
and
2. The lack of maps in the map pack itself.
Even though this is a good map pack the price just does not justify it. Buy it if you a cod fan find another place to spend your msp if your not.
