界面采用开放世界第三人称视角，以主角追溯其刺客祖先记忆而控制其行动。游戏引入「社会状态图像」（Social Status Icon）从而让主角能了解附近敌兵与区域对其祖先的注意程度及警戒状态efn|In-game Animus tutorial program: The Social Status Icon Exposed, Cool Down, Vanishing, Vanished, Anonymous gives you information on your social status.，并以「高姿态」（High Profile）及「低姿态」（Low Profile）区分行动性质In-game Animus tutorial program: The Animus differentiates between two fundamental actions: Low Profile and High Profile.：低姿态行为较容易被社会接受In-game Animus tutorial program: Low Profile actions are socially acceptable.；高姿态行为以行动为中心In-game Animus tutorial program: High Profile actions are more action-oriented.（例如擒拿和抛掷敌人、疾跑）。一旦附近区域对其祖先出现高度警戒状态，其祖先可选择把应战敌兵杀死或逃离敌兵视线范围并躲藏直至警戒回复正常。
其祖先之生命值以主角及祖先之间之「同步值」（Sychronization）显示In-game Animus tutorial program: The Sychronization Bar measures your sychronization with your ancestor.：作出与真实记忆不合之事（如受伤或伤及无辜）会使同步值下降，失去之同步值能透过重新经历祖先之生活而遂渐回复In-game Animus tutorial program: Should you lose sych, you can restore sychronization by reliving key moments of your ancestor's life, or by respecting the Creed.，降至零点会导致记忆重新开始In-game Animus tutorial program: If you ever fall completely out of sych, the Animus will retore you to your last sychronized position.；作出与真实记忆相同之事（如拯救市民或在每次刺杀行动前对目标作出全面调查）会使同步最高值逐渐提升。完全同步时主角可使用其祖先之第六感官「鹰眼视界」（Eagle Vision）以感知附近人们对其祖先之态度In-game Animus tutorial program: Now that you are fully syched, a new ability is available to you. Refered to as Eagle Vision, this sixth sense helped your ancestor understand the intentions of the people around him.。

2012年9月1日04:02，酒保戴斯蒙·迈尔斯被跨国制药公司Abstergo 劫持作为基因记忆追溯机器「Animus」Vidic: You're inside the Animus. Desmond: Which is...? Vidic: It's a projector that renders genetic memories into three dimensions.的第十七个实验体In-game Animus tutorial program: Hello, Subject Seventeen.，目的为获得其活跃于1191年第三次十字军东征时期、隶属敍利亚刺客组织之刺客祖先－阿泰尔·伊本·拉阿哈德（Altaïr ibn La-Ahad）的一段记忆。
当年阿泰尔奉命与两名同伴到所罗门圣殿寻找一个古代遗物，却对于自己过度自信Altaïr: Robert de Sablé. His life is mine. Malik: No! We were asked to retrieve the treasure and deal with Robert only if necessasry. Altaïr: He stands between us and it. I'd say it's necessary. Malik: Discretion, Altaïr!. Altaïr: You mean cowardice. That man is our greatest enemy, and here we have a chance to be rid of him. Malik: You have already broken two tenets of our creed. Now you would break the third: do not compromise the brotherhood. Altaïr: I am your superior, in both title and ability. Youl should know better than to question me.，不但被刺客之宿敌圣殿骑士团阻止Robert: I spare you only that you may return to your master and deliver a message.且违背了三大刺客教条Rashid: Three simple tenets, which you seem to forget. I will remind you.：不杀无辜Rashid: First and foremost: Stay your blade... Altaïr: from the flesh of an innocent. I know.、不暴露行踪Rashid: The second tenet is that which gives us strength. Hide in plain sight. Let the people mask you such that you become one with the crowd.、不连累刺客组织Rashid: The third and final tenet, the worst of all your betrayals. Never compromise the brotherhood.。于回到刺客组织位于马西亚夫的堡垒后，刺客组织之首拉希德丁·锡南（Rashid ad-Din Sinan）把阿泰尔降至最低级别Rashid: You'll see that you've been stripped of all your possessions. Your rank as well. You are a novice, a child once more, as you were on the day you first joined our Order.，同时命其刺杀九名位于圣地（耶路撒冷、大马士革、阿卡）内的骑士团重要人物以作赎罪Rashid: I am offering you a chance at redemption. You'll earn your way back into the brotherhood.，为十字军及撒拉森势力之间带来和平Rashid: I hold here a list. Nine names adorn it. Nine men who need to die. They are plague bringers, war makers. Their power and influence corrupts the land and ensures the Crusades continue. You will find them. Kill them. In doing so, you sow the seeds of peace, both for the region, and for yourself. In this way you might be redeemed.。
阿泰尔把各人逐一刺杀，并了解众人之目的为利用从所罗门圣殿取得之古代遗物控制人民思想以带来和平，而圣殿骑士团之最终计划为联合十字军及撒拉森势力以摧毁刺客组织，但阿泰尔在刺杀最后一名目标－圣殿骑士团大团长罗贝尔·德·萨布莱后始悉拉希德丁乃圣殿骑士Robert: Nine men he sent you to kill, yes? The nine who guarded the treasure's secret. Altaïr: What of it? Robert: It wasn't nine who found the treasure, Assassin. Not nine, but ten. Altaïr: A tenth? None may live to carry the secret. Give me his name. Robert: Oh, but you know him well, and I doubt very much you'd take his life, as willingly as you've taken mine. Altaïr: Who? Robert: It is your master, Al Mualim.，因企图独占遗物而派遣阿泰尔刺杀其余九人Altaïr: I have no interest in the treasure. Robert: Ah, but he does. The only difference between your master and I, is that he did not want to share.：该遗物名为「伊甸碎片」Rashid: That's all it's ever done, this Templar treasure, this... Piece of Eden.，能控制人类思想及造出幻象Rashid: He who holds it commands the hearts and minds of whoever looks upon it, whoever tastes of it, as they say.，而古代之超自然现像包括古埃及法师把手杖变成蛇、摩西分红海、特洛伊战争中神明显灵、迦拿的婚礼中水变成酒等全为此遗物造出之幻象Rashid: This... piece of silver, cast out Adam and Eve. It turned staves into snakes, parted and closed the Red Sea. Eris used it to start the Trojin War, and with it, a poor carpenter turned water into wine.。在阿泰尔回到刺客组织堡垒后Rashid: So... the student returns. Altaïr: I've never been one to run. Rashid: Never been one to listen either.，拉希德丁利用碎片造出各种幻象与阿泰尔展开决斗。阿泰尔击破各幻术后刺杀拉希德丁Rashid: Impossible. The student does not defeat the teacher. Altaïr: La'a shay'a waqi'un moutlaq bale kouloun moumkine. Rashid: So it seems. You have won then. Go, and claim your prize.，碎片亦于此时投射出全世界其余多块碎片位置的立体影像。
Abstergo 在取得该段记忆后Abstergo: Well? Vidic: We've got the map.计划把戴斯蒙留待日后处决Lucy: We might need him, his memories. I'd recommend we hold him until we have confirmation that there aren't any surprises waiting for us at the sites. Abstergo: Very well. Ensure we have no further need of him, then kill him.，但戴斯蒙在研究人员离开后Vidic: Don't get too comfortable, Mr. Miles! We'll be back for you soon enough.看见实验室地上及墙上出现以鲜血写成之文字：因长期进入Animus 而出现之副作用－「出血效应」（Bleeding Effect）使戴斯蒙拥有了鹰眼视觉Assassin's Creed II. Lucy: We're going to train you - turn you into one of us. Desmond: What?! No, no... you've seen me in action - I'm no good at this. And even if I was... it would take months - years, even. Lucy: No. Not with the Animus. Not with the bleeding effect... If you can follow in his footsteps, you'll learn everything he did - just like he did. Years of training absorbed in a matter of days.，看见第十六实验体自杀前以血写下之2012年预言及其他加密讯息Desmond: Oh my god! It looks like... is that blood? Who the hell were they keeping here before me? What happened to him? What does it mean, I wonder.。
戴斯蒙、现代刺客及Abstergo（现代圣殿骑士团）之事迹于后继作品《刺客信条II》中续有叙述。

在《波斯王子：时之砂》完成后，游戏设计师Patrice Désilets获指示开发另一款波斯王子游戏。游戏灵感来自哈桑·沙巴，并以《波斯至子：刺客》之名开始开发。Désilets认为以王子作为主角并不吸引，因此该王子被安排成为需要由玩家操纵之刺客拯救之人工智能角色，但育碧不希望开发一款不以王子为中心之波斯王子游戏，游戏最终变成新的知识产权，王子角色也被删除。
2006年9月28日，开发者Jade Raymond在与IGN的会谈中表示主角阿泰尔是一名过去不明之中世纪刺客，而他也不是一名时空旅行者。于2006年12月13日另一次IGN会谈中，配音员Kristen Bell谈及游戏剧情：剧情将围绕基因记忆以及一个欲寻找刺客后裔之机构。
Raymond也于一会谈中表示游戏灵感来自1938年小说《Alamut》。
