Call of Duty: Strikeforce (3DS Version)

The Nintendo 3DS, due to it's lack of power, had to get a completely different version of Call of Duty: Strikeforce created by an entirely different developer. None-the-less, Activision didn't want another disaster like Black Ops Declassified, so they made sure to pump a good amount of money and talent into both versions.

For the 3DS Strikeforce is the only game, Extinction being a PSVita exclusive.

Campaign
The developers of the 3DS version, in contrast to the developers of the PSVita game, chose to focus on campaign. Instead of several missions from each era of Call of Duty, the 3DS Strikeforce ties more into Call of Duty: Ghosts, taking place during and immediately after the ODIN strike.

Missions
More info to come probably. Ghosts's story was absolute s*** so I don't know if I'll bother.
 * Behind Enemy Lines
 * Work under-cover to get as much information about the Federation's plans as possible, and survive impossible odds after you get discovered.
 * Wrath of ODIN
 * Return to America just in time to see the devastation unleashed by the government's unneeded super-weapon that obviously didn't have enough security measures in place.
 * Strikeforce
 * As the Federation makes it's first move of full-scale invasion, you are you're team need to strike fast and hard.
 * Fourth Mission
 * Fifth Mission
 * Sixth Mission
 * Seventh Mission
 * Eight Mission
 * Ninth Mission

Multiplayer
The multiplayer has far less features then it's PSVita counter-part, lacking the Strikeforces, visuals, or larger maps. It does however still feature an eight player limit with ten different maps with a couple different game modes.

Nazi Zombies
The developers did their best to include zombie mode as well. Players can play through remade versions of the original maps featuring weapons from the campaign as opposed to World War II.

The maps are:
 * Nacht der Untoten
 * Verruckt
 * Shi No Numa
 * Der Riese
 * Kino der Toten
