New to the campaign is a series of optional “strike force” missions, which is meant to take sort of a real-time strategy approach. You command units, moving them to defend or attack various points, while retaining the ability to jump into any one of them and take direct control. On paper it sounds pretty cool. In practice it feels like a work in progress. Unmanned units are largely impotent and splitting your forces never works. Instead you just end up ordering everyone to advance on a specific locale and jump from one unit to the next, killing as many enemies as you can. If Treyarch plans to bring the concept back next time it definitely needs some fine tuning.
