CTF
CTF is back. A big hit in the original CoD and in CoD2, it was absent in CoD4 and was highly missed by gamers. Treyarch must have noticed that CTF was one of the first gametypes modded into CoD4 by the community. While CTF never did catch on, even on proven CTF maps, hopefully it will fare better in CoD:WW.
War
A new gametype that will allow you to drive vehicles in Multiplayer.

REWARDING SUCCESS
Did I mention how much we hated the Helo and Airstrikes in CoD4? Sadly, non-player controlled MP elements are back in WW: a fact that was foretold to us by Josh when we interviewed him in BASH 77 last week. Note that CoD:WW has kept a lot of this type of commonality in CoD4, whose gaming engine it is using, so as not to unbalance gameplay.
Recon Plane
Frag three of the enemy without dying and you get to deploy the recon plane. It temporarily shows you the location of your foe on a RADAR box in the top left of your screen. This of course matches the UAV in CoD4.
Artillery Strike
Frag five enemy combatants and you get to select a strike zone on the map. A few seconds later...whammo! The artillery shells hit the target. This of course replaces CoD4's dreaded aimbot Helo.
Dogs of War
In a bizarre twist, if you frag seven enemy soldiers, you get to release Attack Dogs onto your foe. The dogs chase down and kill the enemy. They will also see out any camped units hiding in the weeds. DoW replaces the CoD4 Airstrike.

ATTACHMENTS
Scopes
Rifles and SMG's will get aperture sights, telescopic sights and sniper scopes
Bipod
A constant in just about any CoD mod ever developed, a Bipod will be available for snipers and MG'ers. You will be able to use it in the prone position to reduce recoil. This attachment makes us us ask the obvious question: is everything bi- these days?
Enlarging your Magazine
You can add a dual magazine or drum magazine onto your weapon for even more praying and spraying ability.
Suppressors
Suppressors hide muzzle flash and somewhat quiet your weapon - but this will undoubtedly come at a cost as the hit power will be marginally less.
Double-barreled Shotty
A double-barreled shotgun will be available. You can "saw-off" the barrel on these to make the gun an overpowered short distance killing machine. Enormous spread for a short distance. Let the "super-noober-toober" chants begin.
Bayonets
The bayonet allows you to extend the reach of the combat knife. This could be quite interesting as knife vs. bayonet only fights would be quite the spectacle.
Flak-Jacket
The new Juggernaut. A grenade-resistant flak jacket will allow you to survive more punishment - undoubtedly at a cost to movement.

THE PERKS
In CoD4, the more you played, the more stuff you unlocked in the game. These were called perks: better gun, attachment and ability unlocks. As you can imagine, "Perks" became an instant fave online in CoD4. There are fifteen new perks in CoD: WW...many are simply renamed CoD4 perks, but some are brand new and specific to WW.
M2 Flamethrower
High level unlock, the flamethrower has been featured as one of the must-see weapons in CoD: WW.
Pyromaniac
Extends the damage range of your grenades - the WWII version of Sonic Boom
Satchel Charge
WWII's C4. You can damage infantry and of course tanks if you place them on the treads.
Bouncing Betty
CoD4's Back-to-the-Future Claymore. These seriously dangerous devices were mines that would spring upward if triggered, spraying fragments at a height that would not just mame ...but kill.
Bazooka
Unhappy with your tiny weapon are you? Grab the bazooka. Size does matter and you can destroy tanks with it! Much more destructive than those silly CoD4 RPG's.
Flak Jacket
The new Juggernaut. Get added health benefits (or come to Canada - they're free here).
Shades
To counter the flare (the CoD: WW flash-bang, which lasts quite a lot longer), you can use "shades" which reduce the blinding effect.
Gas Mask
Reduces the effects of the Tabun nerve gas weapon.
Second Chance
Last-Stand with a twist. As in CoD4's Perk, when you get fragged, you drop to the ground for a few more seconds with only a pistol as a weapon. You lie there waiting for death...however, in CoD: WW, as reported here a few days ago, the new "Second Chance" perk lets you get resuscitated by a teammate who also has Second Chance. This is a nice idea, but I suspect that it will get both you and your teammate killed more frequently.
Fire Proof
A counter to the Molotov cocktail and the Flamethrower.
Dexterity
The new Sleight-of-Hand. This will allow faster reloads and allows you to throw Molotov's and set Bouncing Betty's faster.
Greased Bearings
Allows you to traverse faster with the main gun, and thus get to targets quicker, when you are fighting in a tank.
Ordinance Training
Boost the firing rate of the tank's main gun.
Water Cooler
The tank's machine gun can overheat unless you have this perk.
Lead Foot
Boost the speed of your tank.
