Hacker

- tames take control of several A.G.R Drones on the map
- only weapons available were pistols with very limited ammo and EMP grenades
- use EMP grenades to stop the A.G.R Drones long enough to be hacked and controlled
- the more under your ownership, the better.

"(The mode) just wasn't ready yet. We wanted to give it more time. I wouldn't say it's gone forever. I really liked it, and I know a lot of other people did, but you have to prioritize your time at some point. Even though that was pretty developed, we felt like we wanted to keep working on it so maybe the fans will see Hacker at some point." - Mark Lamia, head of studio at Treyarch
