One example of this that Activision cited was a flood rushing into a map mid-session. Today, announcing a free map as a perk for pre-ordering Call of Duty: Ghosts, the publisher has detailed yet another instance of jeopardizing geometry: the inside of a slowly collapsing skyscraper.

Bonus maps as pre-order perks aren’t new to Call of Duty – Call of Duty: Black Ops 2 offered its preliminary adopters access its Nuketown 2025 map last year – but shape-shifting, precipitously-falling-down-to-Earth maps? Quite another story. Activision says its new level, entitled Free Fall, “drops players into a shattered skyscraper on the brink of collapse.”

From there, metaphorically speaking, it’s all downhill:

According to Infinity Ward executive producer Mark Rubin, dynamic map events like the ones built into Free Fall are meant to encourage players to think strategically, “on the fly.” They’re also one of the many new features the develope plans to unveil within the coming weeks:

With July 2 marking the Xbox 360 release of Call of Duty: Black Ops 2’s final DLC pack, “Vengeance” (PlayStation 3 owners will receive access to the content in August), expect the marketing campaign for Ghosts to come alive in full. The game had a reliabliy solid outing at E3 2013, showing off three levels of its single-player campaign. But for the first time since Call of Duty exploded as a gaming, even pop cultural, phenomenon, the series will have to compete with publicity of two next-generation console releases – not to mention the plethora of exciting launch titles that both the Xbox One and PlayStation 4 have already lined up.

Ranters, will Free Fall, dynamic multiplayer maps and the rest of Call of Duty: Ghosts new, next-genish features entice you to buy in on the franchise’s tenth installment?

Call of Duty: Ghosts releases November 5, 2013 for the PS3, Xbox 360, PC, and Wii U. The game will also hit the PS4 and Xbox One, but an official release date has yet to be issued for either one.
