Activision has announced that a playable, single-player demo for Call of Duty: Black Ops has released on both Xbox LIVE and PlayStation Network.

"Revered as one of the most gripping levels in the blockbuster title that shattered entertainment records, WMD is a heart-pounding experience that takes players deep behind enemy lines as an elite Black Ops operative engaged in covert warfare, classified operations and explosive conflict," reads the press release.

"Players defy death every step of the way as they infiltrate Soviet airspace in the SR-71, the most advanced, high-altitude, long range strategic aircraft imaginable. Deep behind enemy lines, players will engage in intense combat in the harshest of conditions, and scale a formidable, hidden enemy base perched atop a snow-filled mountain range."

We at Game Console wonder who exactly Activision is trying to convince, here: Call of Duty: Black Ops already boasts over 18 million unit sales since releasing last November, when it became the largest entertainment launch in history. Well, if you're one of the few that didn't buy into this one, now's your chance to see what all the hype is about for free.
