一、《使命召唤7:黑色行动》firststrikepack介绍
日前（2月1日）游戏卖场放放了《使命召唤7：黑色行动（CallofDuty：BlackOps）》FirstStrikePack供玩家下载，售价1200点微软点数的附加地图套件包里，增加了BerlinWall、Discovery、Kowloon、Stadium四张多人对战地图外，还拥有一张全新的僵尸模式地图Ascension。四张全新的对战地图将战斗的距离加大，并在场景中还有许多有趣的设计，让玩家能体验更加刺激的游戏内容。以下是各地图的介绍：
BerlinWall：
这张地图即是二战迷最熟知的“柏林围墙”，它是以左右二侧对称的地形，以及中间二道筑起的高墙所构成的场景。在战斗的过程中双方都得小心二道高墙中间的红色区域，若玩家误闯会遭到二侧的重机枪扫射。此外，这张地图非常适合喜欢中、远距离攻击的玩家游玩，特别在围墙中段的缺口处，利用狙击枪或突击步枪可有效阻止对手的快攻。二侧建筑物皆能进行埋伏、防守等多种战术，是附加地图套件包中值得推荐的地图之一。
误入红色警戒区域立即会被乱枪扫死。
柏林围墙中段的缺口处是战况最激烈的地方，尽量利用矮墙缺口做掩蔽可有效降低中弹机率。
打团战时可将中、远射击的人员部署在二侧建筑物的二楼，切断敌方推进的位置。
Discovery：
这是一张以废弃军事基地为场景的地图，拥有超多建筑物可藏匿并搭配高低起伏的地形，加大了整张地图的攻击范围。战术方面，玩家可直接占领侧边的铁桥，除了能直捣敌人的阵地，同时也可以侦查远方敌人的动向，特别是在铁桥上布署二名狙击手，进而达到攻守兼具的战术。这张地图中担任近战突击的队员也有相当重要的地位，因为在抢点模式中的B点设定在地图正中央的桥上，若没人使用烟幕弹与手榴弹协助占点，则会形成双方僵持不下的战况。
该地图占点模式的B点位于地图中央的桥梁上，须派出突击兵强攻才能轻松拿下此据点。
侧边的铁桥可快速推至敌方阵地，几乎是双方阵地最重要的锁匙，若成功攻击此要地等于拿到了胜利的入场券。
Kowloon：
以香港九龙为舞台所制作而成的地图，是一张地形极为复杂的场景。参战的双方人马皆以民房顶楼为战场，到处都看得到顶楼加盖的铁皮屋、水塔等物件，玩家在进攻时必须小心敌人躲在这些地方埋伏。这样的地形设计非常适合喜爱近战的玩家游玩，特别是手持冲锋枪搭配Lightweight技能，开场一分钟即可快攻至敌人后防，将战况迅速拉至沸点。值得一提的是，这张地图设有二个高空溜索，玩家可利用溜索滑至下栋建筑物的顶楼作为撤退、快攻的利器。
高空溜索首度出现在多人连线模式中，让战况变得更有趣也更具战术功能。
想在Kowloon地图中打出漂亮的胜仗，除了要团队的默契之外，还要有过人的眼力才行。
阴雨绵绵的九龙城，整体的气氛营造相当有水准。
#p#副标题#e#
Stadium：
以近战为主要攻击方式的体育馆，适合游玩多人连线模式的各种玩法，虽然地图侧边有一座冰上曲棍球场，但能行走的范围并不大，因此主要的战斗位置还是会以中央广场为首。最令人无法抗拒的就是工地二楼，那里能直接俯视抢点模式的所有据点，如果顺利攻／守住任二个据点的话，对手几乎没有还手的余地。
工地二楼能直接观察三个据点的状况，守住这里能稳胜不败。
与工地二楼相对望的建筑物，是唯一能从远处射击工地最好的位置。
Ascension：
Ascension是这波DLC全新的僵尸模式地图，以诡谲的火箭发射场为舞台，地下室还有多种不知名的秘密实验室。僵尸的类型增加了特战队员、外星太空猴、太空人等，而且最恐布的是僵尸已不再傻傻地只会沿着道路前进，它们会从一楼直接跳到二楼的平台来追杀玩家，甚至还会绕到屋顶上从背后给予意外的惊喜。武器与贩卖机技能部份，在全新的僵尸地图中有也一些新的玩具，像是笔者在抽抽乐（随机武器箱）里抽到“外星手榴弹”，丢掷后画面会出现耀眼的紫色光芒，被波及到的僵尸会立即化成灰。
全新的僵尸外观模组：僵尸医生。
僵尸会从二楼跳到一楼或从一楼跳到更高处来追杀玩家。
新武器“外星手榴弹”。
开启场景的总电源后，玩家可搭乘高空电梯移动到下个房间，暂时躲过僵尸的攻击。

三、firststrike怎么玩
首先看下面这张图，刚进入游戏的时候，点击一座有你控制的城市，就会出现下面图中的选项。我们按顺时针，从第一个骷髅图标处讲起。
First Strike：所有城市发动核打击（漫山遍野的核弹头啊）。
Attack：该城市单独发动核打击（试探性攻击）。
Build cauise：建造一个地对空防御导弹（攻击射程狭窄，通常是防守用的，一城一枚妥妥的）。
Build irbh：建造一个核弹头（攻击射程较广）。
（除此之外，学习到新科技后，还有一个射程更广的核弹头）
DEBUILD：放弃一枚导弹。
RESEARCH：学习新科技。
EXPAND：扩张。
