The Sacrifice will be available on both  versions of the game and depending on what game you download you will get different benifits. L4D gives you the new campaign playable in versus and survival. L4D2 will give you the option of playing The new Sacrifice and no mercy campaign and the joys of using the original cast of survivors with the L4D2 new weapons and special infected, Bill toting a m60 anyone ?

DLC is due to be around 560 MS points

The Sacrifice will fill in the gaps between the end of the original game and the Passing. The DLC will follow the original survivors and will explain how they met up with survivors of Left 4 Dead 2.

The Sacrifice will also allow players to make the decision to which original survivor will perish, this adds a spin on things as The Passing revealed that Bill had been killed in an unseen event. The Sacrifice offers more than the ability to kill of your most hated survivor as the add on will also allow Left 4 Dead 2 owners to play through the entire No mercy campaign with the added weapons and infected found in Left 4 Dead 2. A very cool deal indeed and more extra game hours filled with co-op run and gun action.

The Sacrifice will be free to download for both PC and Mac users while the Xbox Live version will cost a yet to be revealed price.

“The Passing” takes place just after the Dead Center campaign of L4D2. Set in a small town in rural Georgia, where will see the sequel’s survivors meeting up with the original game’s (L4D1) cast. No specifics have been made as of yet to determine how the narrative will unfold.

In addition to the new co-operative campaign where we meet the original cast, “The Passing” will include new arenas for Survival, Versus and Scavenge mode and introduce a new co-operative challenge mode game-type. The Passing will also include a new “uncommon common” zombie class, melee weapon, and firearm.

Left 4 Dead 2: The Passing is targeted for release in early spring for the PC and Xbox 360. Pricing has yet to be announced, but we expect to know more about that closer to launch.

The demo for surprise sequel Left 4 Dead 2 was recently released and I spent about two hours of my gaming life today enjoying it (a rare occurrence these days, if I do say so myself). The game features a hefty amount of pseudo-zombies (real zombies do not run) for you to dismember and smack with the underbelly of a frying pan for pure amusement while the story appears to be there just to give reason as to why you are committing the aforementioned acts on these so called “zombies” (although, having said that, I have read that L4D2 will in fact feature a story arc). Having skipped the original L4D due to assuming it wouldn’t be my kind of game, I had only my vague thoughts of “typical zombie shooter” at the ready as I launched the demo and, as a result of this, I was very pleasantly surprised.

After kicking things off with a very attractive intro cinematic, I stumbled into a pre-made lobby hosted by a friend and chose my character from the list of what I like to jokingly refer to as the “Class of Ethnic Stereotypes 2009”. As soon as the game had finished the loading process, the first thing I noticed was the water. The water looked so good that it managed to hold my attention long enough for me to be left behind by my team mates and subsequently almost dying at the hands of the undead. The zombies themselves were very entertaining; running and jumping at you from almost all directions, vomiting on you, strangling you and being deceivingly smart all at the same time, they niche themselves perfectly in-between infuriating and impossibly fun to fight.

It seems that everything in the demo is as near to perfection as a first person shooter can get; refined controls and fluid movement made this demo a dream to play. The balance between sneaking around to avoid attracting the horde of zombies to trying your hardest to kill that very horde is very fragile and either side can tip the scales at any moment. All of this coupled with the quite stunning visuals and intense/ambient (depending on the situation you are in) sound design really do cast away any thoughts that a sequel is too soon. Although there were a few minor technical hitches here and there (a few bouts of lag and sound deficiency), this game just bludgeoned its way onto my list of “Must Buy” games.

So take a look at the Easter Egg found in the Left 4 Dead 2 demo. It’s found on a Jukebox in a cafe’ just after you climb onto a truck. I’ll leave the surprise intact – but if you didn’t get the reference, shame on you.
