Personally I like the new maps. I love the environmental 'hazards', the graphical look and the way they play too. For a Call of Duty game, Treyarchs Maps are a lot better in design and thought than Infinity Wards - certainly in the last few games!
The Peacekeeper is an 'interesting' weapon. Overall I do like it but all the matches I played were dominated by its use - I know it is early days and I certainly want more time with it before I make a final judgement.
I really enjoyed playing 'Die Rise' and I think this can easily become my favourite Zombie Map in BO2. It is much more like the DLC maps (Call of the Dead, Ascension, Moon etc.) I would rather play this than ANY of the 'Transit' maps! Turned is interesting but as it uses 'Diner' only and has only 4 people too so gets a bit boring quickly. It would be much more fun if they had AI zombies too. Maybe with 2 humans. I can see this being tweaked though as the weapon swap times are ridiculous. As soon as you kill a zombie you progress in weapons (like gun game) but it takes too long to change and more often than not you get killed whilst waiting for the next weapon. I would prefer it (maybe) if it was more like Survival where you can buy weapons from walls - maybe start off with a better pistol than the executioner - maybe the B23R
Overall (and compared to ALL previous CoD DLC) I think this represents the best value for money. he Previous Treyarch DLC pattern of 4 maps and a zombie map (excluding the Moon based Zombie pack) has been bettered because it now gives us the extra Weapon and Zombie game mode.
Whilst it may not be groundbreaking in terms of DLC in general, I do think it is quite revolutionary for CoD and for that I must give them credit. I just wish I could say the same for the team behind the lack of a 'Fix' for the problem with playing Local and online (losing CC slots, permanent unlock tokens, challenges, playercards emblems and having all your stats corrupted!!!
