It’s not inconceivable to think that, heading in to 2012, Activision and Treyarch weren’t prepared to make many detailed, content-heavy announcements concerning¬†Call of Duty: Black Ops II. Much of what we know about the game –¬†and in regards to multiplayer we could probably say most – stems from leaks through internal or external sources, and it seems just as effective to let the word spread virally as it does to, say, hype a world premiere trailer during the NBA Playoffs with a week-long website puzzle game/countdown timer.

Today provided two such examples: The list of achievements for Black Ops II has leaked online offering up insights – occasionally spoilerific – on its gameplay features and storyline. A new set of trailers and screenshots has also emerged out of a private preview event, administering a first look at three Black Ops II multiplayer maps.

Let’s start with the maps.

Last week the unofficial total of Black Ops II multiplayer maps was brought to 14 when a comprehensive list of details was leaked online, updating an earlier comprehensive list of map details that leaked… online. The unsubstantiated nature of the whole process will of course leave room for edits, but three of maps listed – Hijacked, Express, and Overflow – are the setting for the concrete videos and screens appearing today.

Thanks reveals regarding Black Ops II’s weapons, loadouts, and killstreak and perk systems, there’s not much more on gameplay we can derive from the footage. We can, however, digest what likely constitutes a final build of the game (Black Ops II releases on November 13), as well as form a picture of the three new maps. Hijacked, in the first video, takes place on a luxury super yacht where frenetic close quarters engagement steers the action; Overflow, in the second, transpires in cluttered urban streets of Peshwar, Pakistan; and Express, viewable in the first screen below, offers up long- to medium-range engagements in a Los Angeles bullet train station.

But, as hotly anticipated as multiplayer is in Black Ops II – for the purpose of playing it and panning it, annual traditions both – it’s only one facet of a game also looking to provide substantial new content across a single player campaign and the returning Zombies mode. And each is encompassed by achievements.

[Now might be an appropriate time for the spoiler-weary to turn away.]

The full list that surfaced on Xbox 360 Acheivements – in all likelihood it pertains to PlayStation trophies, as well – contains 50 achievements worth the required 1000 Gamerscore points. Many of the resolutions to each campaign mission are laid out quite plainly, including the capturing and interrogation of main villain Raul Menendez and a previously unknown quest to hunt down Manuel Noriega – a real-life Panamanian dictator and warlord whom the United States brought to justice in 1989. Buried in the list are also hints about a new deadly device, the “Karma weapon;” time traveling from 2025 to the 1980s, perhaps to retrieve the weapon; and new gameplay strategies designed for the Zombies mode.
