The player will start each game with two Lightning attacks and will always start each round with at least one (gaining one if the player had zero the round before).

It contains many references to the zombie mode in Black Ops and World at War; however, in actual fact the gameplay has almost nothing in common with those games.

Firing is controlled with the right stick, while movement is controlled with the left.

The player need not worry about ammo, because the your characters main weapon has unlimited ammo and never needs to reload.

The player can also pick up a large number of weapons and power-ups in order to assist them throughout the levels.

Throughout the levels, the player will also be required to pick up treasure (which is marked by a gold or silver tint) to fill a bar at the top of the screen.

When this bar fills up, the players score multiplier goes up by one.

Gems are especially useful in filling the multiplier bar but are uncommon.

Whilst playing cooperatively, if a player loses all their lives they will enter revive mode in which they will respawn in one minute and thirty seconds providing at least one other player is alive at the time, also, if a player enters a new round before the bar empties, then the player downed will automatically be revived.

If, however, another player on the team has at least one life then the player will automatically be gifted that life to be revived instantly.

This grants the player who gave the life a random power-up (either a tank, a helicopter, three nukes or three lightening bolts) and this can only be done once per round per player.

The individual rounds within the levels are all very similar to each other, usually either being a reflection of the other levels or, later on, different weathers that can obscure the players vision.

The zombies on these rounds are the standard zombies and are largely very slow and easy to kill.

Zombies are very much the same as on the Island levels, however, they do gain an increase in numbers and speed.

Electric spikes make their first appearance within this level.

There are steps either at the top or bottom of the map that lead to a large square catwalk that surrounds the map.

Vision on these rounds is slightly more impaired than that on other rounds.

Between any two rounds in the Cave, the player will be taken to the Room of Fate (see below) where a permanent power up is granted to the player.

The reintroduction of levels is largely the reason for the enclosed space having a large staircase just off the center of the map and another staircase in either the top-right or bottom-left corners of the.

Zombies will enter the map from the corners rather than the sides yet there are also two entrances on the side with the staircases, one on top and one underneath.

These rounds have flaming barrels that bounce onto the map from the rooftops which can be shot at to blow up any enemies.

Zombies and Hellhounds will appear through the line of trees from the top of the map allowing a slightly hidden approach.

The player will start each game with one bomb and each time a bomb is used it will kill all enemies on the map (much like when a nuke is picked up on other zombie game modes).
