Overall rating 9.6/10
The guns are good, but the SMG's are REALLY overpowered, the guns have a basic rule(s) for them:
1. If it's really strong it's a single fire rifle
2. If it's strong it's a slow firing massive recoil SMG
3. If it's medium strength, it's medium speed firing, and medium recoil
^ this gets really annoying, as there are no automatic, strong, minimum recoil guns ( like the G36C was in COD4
The maps are mostly big apart from 2, which you rearly ever play on TDM
The graphics are awsome, if you blow up someone with a grenade, sometimes their libs go flying off
The camping is good as a lot of maps have grass
The vehicles are really bad, i hate the tanks, they kill you basically instantly, but take an age to kill with anything other than a bazooka which takes over your perk 1...
The grenades are extremly underpowered but there are 3 types, classical pinapple (the ones used on COD4, just MUCH weaker), sticky (medium strong grenade, sticks to anything it touches, explodes after 2 seconds of sticking to something, you can't cook it), Moltov (very weak, big area of effect, explodes on impact, good on HardCore though
I would say that WaW is as good as COD4, not better, not worse. The sniping on Cod4 is better (the snipers have a better, more comfy feel, all the guns in WaW feel like the Dragunov)
WaW has too many maps with really serious glitches, like getting under the map, or hovering to some really high spot, COD4 had fun glitches where you could climb ontop of buildings and snipe people, but they could see, and snipe you
