泄密、偷跑，那是晶体动力接手古墓丽影系列以来的一贯“传统”[1]。游戏偷跑的时间越发提前，到正统作品第九代的古墓丽影时，甚至提前很久就泄露了游戏思路，并在E3期间又泄露了一部分游戏流程视频。
剧情和概念图泄密
古墓丽影9的消息虽然是由 Game Informer 在2010年12月全球揭幕的，但其实早在2009年年中就已经泄露。
一个名为 4Player Coop的网站在当地时间7月11日凌晨2点多发布了一批古墓丽影下一代的图片，均为屏摄，是有人在晶体动力拍摄到的关于古墓丽影新作的概念图和游戏说明。虽然晶体动力很快给该站发去了律师函要求其删除这些图片，但它们早已在网上传开。
之后，在网站播客中，该站管理员又长篇大论地谈论这次泄露事件。作为一个名不见经传的小站，获得如此重量级的爆料令他们兴奋异常。
当时古墓丽影中文站对此作了追踪报道，见：
在2013年游戏发售后，描述游戏开发历程的《幕后时刻》里揭露了这次泄密事件的内幕。当时晶体动力正在为重启作寻找设计方向，而这是他们送到其他工作室进行评测的内容，当时游戏暂定名为《古墓丽影：升天》。不知为何，这些绝密的评测内容被泄露了出来。后来晶体动力也认为这个理念不太合适，最后还是放弃了这个想法。
简历泄密
2010年，国外网站systemlink爆料，在一位动作编辑师的网络简历上，赫然出现了Tomb Raider Ascension（2011）的字样，意味着这款古墓丽影游戏预定于2011年发布。
游戏剧本泄露
2011年5月，Siliconera 网站将一段游戏剧本放了出来，声称是来自游戏的配音。但这份东西在该站并没有停留太久，很快就应官方的要求被撤换了下来，Siliconera网站用一份对剧本的详细转述取而代之。

| Cinematic – Videolog1 Page 1 INT. LARA’S CABIN – TWILIGHT We’re watching a video log; Lara is seen leaning into the camera as she draws her hand back from the record button and sits down on the side of her bunk. LARA (Bored) September second. Three weeks out, zero finds, twenty fish suppers, fifty instances of Roth fantasising about a pint of Bitter and a ninety-nine percent chance that I’ll hurl myself off this boat out of sheer boredom. Still, at least I’ve convinced him that the only thing standing between him and his ale is the Dragon’s Triangle. Lara shifts her weight. LARA (Dismissive) There’s the usual folklore rubbish about the place – spinning compasses, cursed ships – but that’s a load of nonsense and Roth knows it. Lara leans into the camera a little. LARA (Growing excitement) We’re close to something, I can feel it. Something extraordinary. And that’s what it’s about after all, isn’t it? Anything less and it’s just a hobby. EXT. VILLAGE – NIGHT Lara is approaching the village when from a nearby distance she hears wolves BARKING and SNARLING. GUNSHOTS follow, and then the sound of Roth crying out in pain: ROTH (O.C.) Gah! Lara rushes toward the source of the sounds. From across an ancient, weathered bridge that spans the distance to a plateau atop a rock spire, she can see now a battle between Roth and a pack of wolves. LARA (To self – relieved) It’s Roth (Calls out) Roth, I’m coming! Roth unleashes a battle cry in response. ROTH Rrrrrah! She rushes across the bridge, we cut to Roth, who sits on the ground with his back to the wall of a ruined structure. He clutches an emptied automatic pistol in each hand. A couple dead wolves lie nearby, amid a scatter of spent shell casings. Roth’s eyes are closed, his teeth are clenches, but he’s obviously still alive. One of his legs is bleeding from a serious wound. Lara runs into frame and crouches down beside him. LARA (Relieved) Oh thank God you’re alive. Roth pries open one eye, smiles and gestures to draw attention to his gun. ROTH (Pained) God had nothing to do with it. (Smiling weakly) It’s good to see you too, girl. Lara touches Roth’s wound and they both wince. LARA (Wincing) Sorry…they did a real number on your leg… She looks around for something to use as a tourniquet. We focus on Roth and can hear Lara tearing off some material – maybe from Roth’s clothes or hers. ROTH (Pained Dismissive) Nah, it looks worse than it is. Lara starts to bind Roth’s leg. LARA Have you heard from any of the others? ROTH (Pained) Nothing. We pull back. Lara’s tied a tourniquet around Roth’s leg. Roth reaches up a hand to be helped to his feet. LARA (Shocked) What are you doing? ROTH Those scavengers took my food pack. The transmitter from the lifeboat’s in it. If we don’t get it back we’re not getting off this bloody island. Lara gestures to Roth’s leg LARA (Worried) You need bandages, antiseptic… morphine… ROTH Also in the pack… LARA (Despondent) Shit. ROTH (Pained) In a word. Roth Holds out his hand again. Lara helps him up and he puts his arm over her shoulder. He staggers and blacks out, Lara almost overbalances as his body slumps to the ground. LARA (Rising panic) Roth! She lies him down and shakes his face. LARA (Rising panic) Oh don’t do this to me you Yorkshire bastard. She checks his pulse. LARA (Semi-relieved) At least he’s still alive. Lara stands up, takes a few deep breaths, She looks around the clearing before squatting down to examine the earth. Lara’s eyes follow the wolf tracks leading off in one direction and she stands back up. LARA (Slight panic) Oh God, what am I doing? Cinematic – Village2 EXT. VILLAGE – NIGHT Lara returns to Roth and finds him still lying unconscious next to the campfire. Lara drops the transmitter and the medkit next to Roth and starts to work LARA (Determined) Right, let’s get you patched up. FADE DOWN briefly and then FADE UP to Roth waking up. He sits up. Lara’s is sitting a small distance away staring into the camp fire. ROTH Not bad. Where does a young lady like you learn to do a thing like that? LARA Late shift at The Nine Bells. A wolf’s got nothing on a broken bottle. Roth looks at the transmitter. ROTH You got it. Nice work. LARA I assume the plan is to get it to that radio tower? We angle on the central mountain peak. ROTH (O.C.) It should give us the best shot of broadcasting a strong signal in every direction. Roth grunts, shifting his wounded leg uncomfortably, He looks at the peak, then at his leg, then back at Lara. ROTH (softly) Lara. We need to send out that SOS and I’m not going climbing any time soon. Lara stares into the fire. LARA (Despondent) I was afraid you were going to say that. Roth reaches out and touches Lara’s shoulder. She turns to look at him – her face a mask of worry. ROTH You can do this Lara; after all, you are a Croft. LARA (Weakly) I don’t think I’m that kind of Croft. ROTH (Encouraging) Sure you are. You just don’t know it yet. Roth reaches over and picks up his climbing axe. He lays it on the ground between them. Lara stares at it for a minute unsure if she should take the responsibility. LARA (Putting on a brave face) Then let’s hope I’m a fast learner. When she does reach for it Roth grabs her wrist gently. ROTH (softly but sternly) Just be careful Lara. Roth lifts his hand and Lara nods before standing up to leave. She slips off into the night without another word. |
游戏流程泄露
E3 2011上公开展示的是“逃出洞穴”部分，除此之外，官方还带去了另一个关卡的演示，但这个关卡只对部分媒体开放。根据E3期间的网络媒体和E3前的游戏杂志报道，古墓丽影中文站对已知的游戏流程进行了整合，因行文随意，只发布在了轻博客上面。
就在发布了这篇介绍的第二天，意大利的一个网站将偷拍的这部分保密状态的流程视频放到了网上，该视频前六分钟是微软发布会的内容，从5分27秒开始就是内部演示。当然古墓丽影官方很快就封杀了这个视频。
E3 2012 泄密
E3 2012 总共出来了两个泄密事件，一是E3前，一张游戏渲染图出乎官方意料地在一个葡萄牙网站被放出，继而被玩家通过 Google 搜索到。但是官方很快就放出了这张图的高清版，它后来也成为E3宣传画的主力。
二是去年那个泄密的意大利网站再次放出内部演示视频，这次还是高清版，内容是劳拉被俘到杀人的全过程，也是预告片后半部分所着力渲染的片段。
-
E3前的泄露版图片，很奇怪的一张。
-
泄露的视频中，劳拉与惠特曼发现一个供奉卑弥呼的古庙，继而被俘。
包装封面泄密
古墓丽影的包装封面于2012年10月23日（北京时间10月24日零点）发布，但在21日，网络上就泄露了这张封面，古墓丽影官方对此一头雾水，又（又！）一次表示不清楚泄露事件如何发生。
-
官方封杀迅速，泄密网站很快用一张玩家涂鸦替代了泄露封面
-
古墓丽影包装封面提前泄露
多人模式泄密
2012年12月底，网上的游戏销售商 game.co.uk 在PS3版游戏预订页面的相关说明中，明确列出了“多人模式”，这一信息很快被删除，几天后Xbox官方杂志 OXM 在封面上正式公布了多人模式，晶体动力在官方博客确认了这一消息，并宣布多人模式由Eidos蒙特利尔开发。

OXM正式公布古墓丽影多人模式
-
OXM之前，PS3预订页面的游戏说明中就泄露了古墓丽影存在多人模式
游戏偷跑
2013年2月24日，距离游戏正式发售还有一周时间，Xbox360版率先偷跑，偷跑的版本是欧版锁区。
