According to the site, Official Xbox Magazine has had a talk with Chet Faliszek about the new game mode, and some ambiguities surrounding the free update. There's no better way to say this than how OXM have said it already, so you can find a quote from them below:
According to the interview with Chet, The Survival Pack will include "15 choice locations" from their standard campaigns. That is not all though. A new Survival map will also be shipped, dubbed: The Last Stand. "With nowhere else to go, our four survivors have retreated to a lighthouse on a point for their final stand.
Survival Mode, places the four survivors on an empty map. They then have the chance to prepare themselves for the endless wave upon wave of infected that will surround them. Once prepared and ready for action, a simple button is pressed and the battle for survival begins.
During the battle, you can expect to fight off up to four Hunters at once. Chances are you might even have to fight of multiple Tanks and Smokers. This fantastic new addition to Left 4 Dead will also sport some new music and a few new survivor quips.
Along with the new Survival mode, we will also get our hands on the official version of Dead Air and Death Toll in versus. We were worried that the levels wouldn't be updated and fixed like the current campaigns have been fixed. Chet assures us: "Both [campaigns] have been heavily modified based on feedback we received from players on No Mercy and Blood Harvest".
So we will be getting a new map after all, which is always good news. You can read the full post over at L4Dmods.com, or look below for the admittedly tiny picture of what might be the new level's poster.
