2010年3月1日和3月3日，传送门更新了一系列侵入式虚拟现实游戏（或称ARG）内容，皆在为续作传送门2进行铺垫。导致当时的玩家和记者们认为传送门2或半条命2第三章很快就会公布。直到V社在2010年3月5日官宣传送门2将会在当年第四季度发布
这一系列的ARG内容都是由传送门2的开发团队独自制作的，背后没有任何的营销团队。虽然其主要目的是为传送门2进行宣传，但这些ARG内容也被认为扩展了传送门的世界观。

测试间02新添加的收音机.
2010年3月1日下午2:33时传送门进行了第一次更新，描述为“修改无线电传输频率以符合联邦和州政府频谱规定”。本次更新增加了一个成就也是正常流程里最难拿的成就——接收讯息（最迷成就，描述仅为...?）。同时在整个游戏流程里添加了总共26个收音机（包括原来就已经有的）。这些收音机很多都放在一些角度刁钻的地方（但靠近时会听到音乐），并且在其开关上增加了红色光晕。如更新中所描述的，所有游戏中的收音机的频率已被更改，以符合“联邦和州政府频谱管理规定”。玩家必须将其带到当前场景的特定位置中，在特定位置时，收音机会受到无线电干扰，接着开始播放摩斯电码或奇怪的数据传输声。此时开关上的红色光晕会变为绿色，同时完成成就“接受讯息”的收集进度
26个无线电音频
于2010年3月1日添加的音频可以在游戏的音频目录下"ambient"找到。这26个音频皆被命名为“dinosaur”。分别为dinosaur01到26、dinosaur_noise（收音机靠近游戏内特定区域时的无线电噪音声）、dinosaur_fizzle到dinosaur_fizzle03（将收音机放入光圈科技分解网格时发出的声音）。从dinosaur01到26的大部分音频都可以使用SSTV软件解析出图像。而dinosaur（恐龙）这个名字的意思是：与当今的技术相比，ARG中所用到的技术是相当古老的
| Sound file | Image | Description / translation |
|---|---|---|
| dinosaur1.wav | 仅摩斯电码 | 将其解析可以得到“内部传输启动，外部数据线启动，信息摘要启动”。 |
| dinosaur2.wav | 包含字母数字“3068”。图像1是一张纸，上面写着“B•dA = 3”（“B•dA”是磁通量的高斯定律），另外3张是键盘按键的图像。 | |
| dinosaur3.wav | 一张带有光圈科技头图的纸，以及一行被划掉的BBS号码："(425) 822-5251". | |
| dinosaur4.wav | 将图中的字符组合得到“C8C2”。第一个C写在一张黄纸上，8则在8号球上，第二个C为白色键盘的C按键，而2则显然是帽子上数字24的2 | |
| dinosaur5.wav | 仅摩斯电码 | 将其解析可以得到“9E107D9D372BB6821BD91D3542A419D6”，“The quick brown fox jumps over the lazy dog”的MD5 Hash值（一个用于测试键盘是否故障的著名短句） |
| dinosaur6.wav | 该图中GLaDOS的一部分. | |
| dinosaur7.wav | Contains the alphanumerics "128B". Reuses the sheet of paper of "dinosaur2.wav". The other images are again keyboards. | |
| dinosaur8.wav | The back of a computer case, with the fan location clearly visible. | |
| dinosaur9.wav | The photo of a skull, two radio tubes and other items on a desk, found at Adam Foster's Flickr account. | |
| dinosaur10.wav | Another view of the sheet of paper with the BBS number. | |
| dinosaur11.wav | Possibly bulbs and a ceramic rooster. | |
| dinosaur12.wav | Only Morse code. | Translates as "system data dump active, user backup active, password backup active".[1] It includes the username ("backup") and password ("backup" again) to login to the BBS number (425) 822-5251. |
| dinosaur13.wav | Contains the alphanumerics "D4FD". Features several sheets filled with math formulas. The red F is reversed. | |
| dinosaur14.wav | Unknown subject seen through a telescope or a similar device. | |
| dinosaur15.wav | A toy cow.[2] | |
| dinosaur16.wav | Contains the alphanumerics "7CC6". Reuses the two "dinosaur4.wav" Cs. The numbers are written on a blackboard with a chalk. | |
| dinosaur17.wav | Only Morse code. | Translates as "BEEP BEEEP BEEP BEEP BEEEP BEEEP BEEEP BEEP BEEEP BEEP BEEP", in turn translating as "LOL".[1] |
| dinosaur18.wav | Contains the alphanumerics "9459". The 9 is on a white keyboard, the 4 is the same as in "dinosaur13.wav", the 5 is apparently on an old typewriter keyboard, and the 9 is written on a blackboard. | |
| dinosaur19.wav | Encrypted phone numbers written in a way similar to that of the Portal credits. | |
| dinosaur20.wav | Contains the alphanumerics "03B8". Reuses the 0 from "dinosaur2.wav". The 8 is likely on the same sheet featuring the 4 in "dinosaur13.wav" and "dinosaur18.wav". Each image contains the Aperture Science "aperture" logo on the bottom left. | |
| dinosaur21.wav | Aperture Laboratories white lab coat, with the collar on the left. | |
| dinosaur22.wav | Reversed image of the inertial navigation system for the Apollo Guidance Computer taken at the MIT Museum in Cambridge, Massachusetts, found at Adam Foster's Flickr account.[3] | |
| dinosaur23.wav | The edge of a circuit board of Herbert, a robot built at MIT in 1987,[4] also taken at the MIT Museum, and also found at Adam Foster's Flickr account.[5] The robot head also found at Foster's Flickr account does not belong to Herbert but another MIT robot named Kismet. | |
| dinosaur24.wav | A mouse trap. | |
| dinosaur25.wav | Contains the alphanumerics "C6CA". Reuses the same C as "dinosaur4.wav" and "dinosaur16.wav", and the same 6 as "dinosaur2.wav". | |
| dinosaur26.wav | Close-in shot of what may be a printed circuit board, seen through a microscope or a similar device. |
