Have you had your morning coffee yet, or your after-lunch Red Bull? If not, then don't bother because after you watch this trailer wherein Callofduty Voiceover Man screams the words ONSLAUGHT DEVASTATION, INVASION, AND NEMESIS at you in quick succession, you'll be so awake that you will never again need the chemical crutch we so lovingly refer to as "caffeine."
Watch the trailer for yourself. If you're using headphones, turn the volume down.
Call of Duty: Ghosts is out right now.
