In the beta version (0.0.3.1.7) of Call of Duty Online, there are a multitude of killstreaks to select from. Most have been seen in Call of Duty: Modern Warfare 2 and Call of Duty: Black Ops, but, there are others that have been added into the game from other Call of Duty's.
Cyborg Evacuation is a game mode featuring some remade multiplayer maps where the player has to find survivors and gather them at the evacuation point whilst being faced with multiple and varing difficulties of Cyborg Zombies. This gamemode is available to play on medium, veteran and heroic. Each one has an ep increasing amount of survivors to be found. Once the player have escorted all of the survivors the player will then have to face a massive boss mother ship along with rapid ammounts of Hellhounds, Cyborg Zombies and boss Cyborgs with miniguns.

Killstreaks and ammo supplies are also placed around the maps similar to the ones seen in the Survival Mode. Ammo can be refilled for free from ammo crates. Some equippment can be purchased using dog tags earned by killing certain special breeds of cyborgs, reviving teammates abd escorting survivors. The gamemode can be played up to 6 player co-op.
Currently the 3 maps available to play for Cyborg Evacuation, which are Bog, Farm (Overgrown from previous Call of Duties) and Ambush, more will be added through updates.
This game is exclusive to China at the moment but there are talks on bringing the game to the rest of the world.
There is a way to play the game outside of China by getting into a Chinese server, but the connection would be very inadequate. The servers are up and running.
