Dismemberment? We know you can handle that. Zombie vomit? I'll admit to some queasiness watching that in action.

Activision's pimping the PC and PS3 release of its Rezurrection map pack, on Sept. 22, with this latest video. It's already out for Xbox 360 of course, and it's at least as believable as Apollo 18.

The fourth and final add-on for Call of Duty: Black Ops, Rezurrection, hits the PS3 and PC September 22, kicking off a double XP weekend. Rezurrection's all-zombie maps include Moon, Nacht der Untoten, Verruckt, Shi No Numa, and Der Riese.

One of the highlights of the Call of Duty XP convention was its paintball field recreation of "Scrapyard," a multiplayer map plucked from Call of Duty: Modern Warfare 2. I took a few stinging paintballs to the thigh and bicep for your enjoyment, if you couldn't make it to Los Angeles this past weekend.

Armed with one paintball gun, some light protection and a GoPro Hero helmet camera—provided by the fine folks at GoPro, thank you very much—mounted to my chest, I ran the "Scrapyard" course for one game of real-life Domination that lasted about seven minutes. Five minutes of that session allowed for infinite respawns, with the last two minutes "sudden death" for Team Black and Team Khaki.

As you watch the above video, keep a few things in mind: we totally kicked ass; I was shot at least six times, hence my frequent trips to the red "respawn point"; yes, I really should have mounted that GoPro on my head, not directly behind my gun; people lined up for hours to experience this Call of Duty recreation and for good reason—it was a hell of a lot of fun.

Take a look at the pint-sized "Scrapyard" recreated for Call of Duty XP above and pray that Activision has the good sense to do this again next year—only bigger.

Activision's social network and stat-tracking service for the Call of Duty enthusiast, Call of Duty Elite, may become your preferred way to meet and play against your fellow first-person shooter fans. It does a whole lot more, but let's take a look at what Elite's Connect feature suite is all about.

Connect is where Call of Duty: Black Ops and Call of Duty: Modern Warfare 3 players will join Groups, start up Clans and delve into the games' Theater modes. It's where Beachhead Studios head Chacko Sonny believes Elite's most useful, most compelling features may lie. There's more in the "behind the scenes" video, if you're interested in what Elite may bring to Call of Duty.

For more on the premium features of Elite, the kind you may feel like paying for, read our pre-Call of Duty XP preview of what's coming to the paid side of Activision's soon-to-launch service.

Hey, you like guns? Then you should really be at Call of Duty XP this weekend. They got guns! Lots of 'em. They even have a FGM-148 Javelin and an alien head. Just head to "The Armory." Or take a journey with me through the magic of photo galleries!

The various arsenals of many Call of Duty games are represented at the XP expo's Armory, from Call of Duty: World At War to Modern Warfare 3. Men dressed as Vietcong, men dressed as Navy SEALs and men dressed as Makarov thinly populate the Armory, intimidating you with nasty looks and huge rifles. But it's all in good fun.

If you can't make it to Call of Duty XP this weekend and enjoy looking at firearms behind chainlink fences, get an eyeful in the gallery above.

In space, no one can hear you scr... yeah, you know the drill. No one can hear much of anything actually, except for the groans of endlessly advancing zombies, and the choked coughs of machine gun fire.

Thankfully, Call of Duty: Black Ops's DLC zombie map "Moon" features an unlockable musical easter egg that dials in a healthy dose of ass-kicking metal to the proceedings. Activating it is a simple matter of finding a few teddy bears, which YouTube user TheMediaCows has been kind enough to share in the video above.

I like how excited his onscreen character gets that he's finally found the music. Though who can blame him? Space can get lonely sometimes. It's nice to have a decent soundtrack.

Treyarch gives us a behind-the-scenes look at the Rezurrection downloadable content coming for Call of Duty: Black Ops, including a look at what happens to zombies in the vacuum of space. BOOM!

Along with the video, Treyarch and Activision have also shared a striking piece of art for the new zombie map included in the pack, Moon. I want this on my wall, now. Where's that printer cable?
