Reloaded also introduces the brand new 'Mi6 Ops Missions' - "new, distinct levels separate from the campaign that span the varied environments from the story and challenge players to complete different Assault, Elimination, Stealth and Defense objectives."
Activision promises 16-player online matches with more maps, weapons, characters and game modes, plus the traditional four-player split-screen action.
You can't "refine" what was essentially a perfect FPS for the consoles. That's like saying we're "Refining" Half Life 1/2. It's just ridiculous.
Still, nice that they kept the splitscreen.
