You can't really innovate CoD unless you set it 100 years in the future so you can make up your own technology. Hmm I suppose the missions, you could have jungle warfare and in it you can climb up trees, hide in bushes, grab people from bushes take their uniform and disguise yourself as the enemy and infiltrate their ranks, jump across trees, snipe targets and jump on unsuspecting targets from the trees.
Hijack tanks from the enemy during campaign, fake your death sacrificing a grenade then sneak away when they think you are dead. Interrogations where you choose how to interrogate your target then use different modes of torture in a series of quick-time event but you need to remember when to stop otherwise they would die. (But that would make reporters who know nothing about the game attack it).
