當一個有知覺的人類個體接近SCP-035時，會感受到一種強烈的，想要將其佩戴在自己臉上的衝動。一旦被戴上，SCP-035會立即導致宿主腦死亡，並以自己的意識佔據宿主的身體。SCP-035能夠控制人類屍體或是一切人形物體（包括模型、雕塑、玩偶？等），所有被戴上SCP-035的人或物體都會隨時間推移不斷被腐化，這一過程不會對SCP-035造成任何影響。已證明動物不會受到SCP-035異常性質的影響。
某日，SCP-035收容間的牆壁突然開始分泌大量黑色液體，且這些液體在牆壁上形成含義未知的圖案與文字，位於收容間附近的工作人員也不斷出現各種精神幻覺，這些現象導致了站點內的人員出現大量自殺行為。基金會曾試圖通過使用SCP-148覆蓋SCP-035收容間牆壁以阻止此類影響，雖在最初取得了部分效果，但很快便使得情況進一步惡化——收容間的門會在人員進入後自動鎖上、內部的電子設備無故停止工作、甚至分泌物中會伸出觸手攻擊清潔人員，最終使基金會不得不將SCP-035轉移至全新的收容間，並將被分泌物徹底汙染的舊收容間密封隔離。
在站點大規模收容失效事件發生後，SCP-035設法將自己附在了一位研究員臉上，並通過無線電求救。若玩家進入了其收容間的控制室，SCP-035會請求玩家將自己釋放出來，承諾會幫助他逃離設施。如果玩家長時間未操作，SCP-035會逐漸變得不耐煩，最終，它會告訴玩家儲藏室的密碼以表誠意——裡面有一片SCP-500以及一份SCP-035的文檔。（使用毒氣折磨它一番也能讓它說出密碼）
Hello? Please? Can anyone hear me? Anyone? I need help, and medical attention too, please!
喂？有人嗎？能聽到我嗎？有沒有人？我需要幫助，還有醫療救助！拜託！
I'm currently in the heavy containment zone, beyond checkpoint E, and I'm locked in SCP-035's containment chamber.
我現在在重收容區，E檢查點後面，被鎖在SCP-035的收容室裡。
Please, I know my way around this compound. If you can get me out of here, I'll help you out of the facility and to the surface!
拜託了，我對這座設施很熟悉。如果你能把我弄出去，我會幫你離開設施到達地面！
—— 通過無線電求助
Oh thank god! Someone actually found me, I thought I was done for a moment there. [Chuckles]
噢！謝天謝地！終於有人找到我了，我剛才還以為我要完蛋了呢。[輕笑]
I can get us both safely to the surface, just find the control panel in there and open the chamber doors for me.
我能帶我們倆安全到達地面，只要找到那裡的的控制面板，幫我打開收容間的門就行。
—— 注意到玩家
Well, what are you waiting for?
呃，你在等什麼？
What, do you not… Alright, I admit it, I wouldn't blame you if you don't think I look trustworthy, but please. I need your help and quickly, the mask has been stuck to my face for some time now, and I think I need medical attention or it might kill me from the inside. Just let me out and I can find us an exit in a matter of time.
怎麼，你該不會……好吧，我承認，你要是覺得我不值得信任也情有可原，但拜託了。我需要你的幫助，而且要快，這個面具已經粘在我臉上好一陣子了，我覺得我需要醫療救助，不然它可能會要了我的命。放我出來，我很快就能找到出口。
[Sighs] I'm starting to lose my patience here.
[嘆氣] 我的耐心快耗光了。
What are you doing just standing there?
你一直傻站在那幹什麼？
You know, the Mobile Task Force will be entering the facility any minute now, guess what they do to stray Class-D's like you?
你知道嗎，機動特遣隊隨時會進入設施，猜猜他們會怎麼對付你這種落單的D級人員？
Fine, good luck getting out all on your own.
行啊，希望你能自己一個人逃出去，祝你好運。
Are you even listening?
你到底有沒有在聽？
Alright, look. If you still don't think I'm trustworthy enough, there's a locked storage room behind you, you probably noticed that it's guarded with a 4 digit pass code. Inside is some useful equipment, as well as a pill of SCP-500. The pass code is 5731, got it? 5-7-3-1.
好吧，聽著。如果你還是覺得我不夠可信，你身後有個上鎖的儲藏室，你應該注意到了需要一個4位數密碼才能進去。裡面有些有用的東西，還有一片SCP-500。密碼是5731，記住了嗎？5-7-3-1。
—— 玩家長時間無行動
You see? You can trust me. Now please, just hurry and open the door!
看吧？我就說我是可信的。求你了，快點開門！
—— 玩家進入儲物室
Unfortunately, I never had any intentions of taking you with me, so this is where we part ways. But for the sake of my freedom, I have reason to believe that SCP-079 is taking control of the facility's systems, including the door system. Your best bet is to appeal to it somehow, hopefully you can come to a compromise, however it does not control the warheads, which you should disable remotely in the event that something goes wrong.
很遺憾，我壓根就沒打算帶你一起走，所以咱們還是就此分道揚鑣吧。但看在你讓我我重獲自由的份上，我可以告訴你SCP-079正在控制設施的系統，包括門禁系統。你最好想辦法和它交涉，希望你們能達成妥協。不過它控制不了核彈頭，如果出了什麼差錯，你得遠程解除它們。
—— 玩家直接將SCP-035釋放
Wait, what the hell are you doing? What the hell are-- [Coughing] Will you please why-- [Coughing] Just please-- [Coughing] I can't breathe! No!
等等，你他媽在幹什麼？你他媽——[咳嗽] 告訴我為什——[咳嗽] 求你了——[咳嗽] 我無法呼吸了！不！
—— 玩家打開毒氣閥門
[Coughing] Thank you. [Panting] Just please, don't do that again.
[咳嗽] 謝謝。[喘息] 求你，別再那麼做了。
[Coughing] [Sigh] Ah, now, was that really necessary? I offer you some help and you try to thank me by suffocating me?
[咳嗽] [嘆氣] 哎，這樣做真的有必要嗎？我好心幫你，你就用把我憋死的方式來報答我？
Now now, I think we got off on the wrong foot here, really. To prove that I'm not up to no good, try that locked door over there, the code is 5731, 5-7-3-1. Got it? You'll find all sorts of goodies in there OK? Please, just not the gas again.
好了好了，我覺得我們一開始就鬧得不太愉快。為了證明我沒惡意，試試那邊那扇鎖著的門，密碼是5731，5-7-3-1。記住了嗎？裡面有好東西。行嗎？求你了，別再放毒氣了。
—— 玩家在SCP-035「死」之前關閉毒氣閥門
Unfortunately, I can't take you with me, you're too much of a liability in many ways. So yes, I did lie to you, but for the sake of my freedom. The easiest way to get out safely, is probably Gate A. The security is pretty high, but if you manage to sneak past the guards and reach the lower level under the bridge, there's an unguarded service tunnel. That's your way out.
很遺憾，我不能帶你一起走，你完完全全就是個累贅。沒錯，我騙了你，但這都是為了我的自由。最安全的出路可能是A門。雖然戒備森嚴，但如果你能潛行繞開那些守衛，到達橋下的下層區域，有一條無人看守的維修通道。那就是你的出路。
—— 玩家在不激怒SCP-035的情況下將其釋放
[Demonic Voice] So, you really don't want to leave this place alive, do you? You know there's no way a lone D-Class like you would make it to the surface safely. Even if you did, they'd gun you down the moment you came across their reticles.
[惡魔般的聲音] 看來你是真不想活著離開這兒了，是吧？你應該很清楚，像你這樣的D級人員根本不可能獨自安全到達地面。就算你做到了，他們也會在你進入視線的那一刻就射殺你。
[Demonic Voice] I'll give you one more chance here, just open the chamber doors, and we'll forget about this little gas incident.
[惡魔般的聲音] 我再給你最後一次機會，打開收容間的門，我們就當剛才的毒氣洩露沒發生過。
—— SCP-035「復活」後
I commemorate you for your help, but I have no further business with you. I have no intentions of taking a person who earned their imprisonment with me. But for the sake of my freedom, the simplest way for you to get out safely, is to go and find SCP-012 in the Light Containment Zone. If you can read between the lines, it'll be as interpretable as a map. Good luck.
感謝你的幫助，但我們就到此為止吧。我可不想帶上一個罪有應得的囚犯一起走。但看在你讓我我重獲自由的份上，我建議你去輕收容區找到SCP-012。如果你能讀懂字裡行間的暗示，它就會像一張地圖一樣指引你。祝你好運。
