Call Of Duty: World War 2 - 10 Iconic COD Features That Must Return

OK, so it can't be called Spec Ops - but the chance to play co-op missions that adapt the single player campaign into gruelling, one-shot challenges is a thrilling one. Borne out of the desire to add co-op into the main campaign, Spec Ops was well-received by players after it was first introduced with Call of Duty: Modern Warfare 2.

The mode also appeared in Modern Warfare 3 and later games rotated between Zombie and Extinction modes to satisfy the desire for co-op gameplay.

The missions could rely on the same types of play: defending points on a map, traversing an area facing off against 'Juggernaut' style foes, infiltrating bunkers with breach and clear style tactics, causing carnage with flamethrowers, defusing bombs or destroying weapons caches in a European village...the possibilities are endless. The chance for the player to go undercover on a stealth mission whilst another player watches over with a sniper rifle would be tense gameplay at its finest.
