==Gameplay==
*THE ABANDONED INN:
thumb|800px|left|After the force field booby trap fight scene, sometimes Alyx gets stuck on this little wall and will not continue on to open the gate to allow you to shut off the power. She won't follow if you get in the car, or try to force her to take cover from a danger. (grenades or explosive items around her)
*IN THE CITADEL, NEAR THE VORTEX BRIDGE:
:Alyx pushes you off the vortex bridge if you stand in her scripted path. --Amckern 07:28, 6 Jun 2006 (PDT)
::Shouldn't you be past the bridge when she's running on that path? --Alph Tech STUART 13:49, 6 Jun 2006 (PDT)
:::I like to test my limits on scripted enviroments. However it was just a bad hair day for Alyx I spose, "Get out of my way, or I'll push you off!"
*WHEN GUIDING GROUPS OF CITIZENS AT THE TRAINSTATION:
:Sometimes a Combine soldier would go through the door to where Barney is, and start punching/shooting him. Barney does not take damage and does not reply. It would be better to just prevent Combine from going through that door completely. —Matveims 16:31, 5 Jun 2006 (PDT)
*IT IS POSSIBLE TO JUMP OFF THE TRAIN AT THE END
:Doing a crouch jump lets you go over the railing of the train in the ending sequence. It would be best to put a clip brush there.--Gman003 14:26, 16 Aug 2006 (PDT)
::Seems fixed now. --Gman003 08:36, 21 May 2007 (PDT)
*AT THE FIRST RAISING BRIDGE SEEN IN URBAN FLIGHT
:After the citizen runs across the bridge and starts it raising he will sometimes run back onto it. The bridge passes through him and he falls to the ground. One way to replicate this is to shoot at the citizen just as he is turning around. (Screenshot) 
--DBN 22:09, 28 Dec 2006 (PST)
*THE HOPMINE CAN ATTACHITSELF TO AIR
:Put a hopmine on your head, make sure it's bottom down, if you wait a while (without it being held by gravgun) it will attach itself to your head, now move away a bit, it'll be suspended in thin air. Then pull it with the gravgun, right before it detaches itself let it go, it'll be hanging in the air attached to one point, if you jump on it it will act like a tiny trampoline(Screenshot).--spliter 13:35, 20 Jun 2007 (GMT)
*ALYX DISAPPEARS WHEN YOU RUN INTO HER
:Right in the beggining of chapter "Low Life" when Alyx leans against the wall(Screenshot) try to run into her. When you're close enough she'll disappear Screenshot, and right after that she'll push you away. --spliter 13:35, 20 Jun 2007 (GMT)
==Graphics==
==UI==
* Chapter names should be in all caps if memory serves. --Alph Tech STUART 12:07, 1 Jun 2006 (PDT)
: I think this is to signify the less milataristic leadership of the vortigaunts (in comparison to the gman) --fuseinabowl 14.22, 6 June 08 (PDT)
* Suit power doesn't disappear when you die from falling. --Alph Tech STUART 15:46, 1 Jun 2006 (PDT)
* 
==Episode 2 Trailer==
*The episode 2 trailer sometimes causes a crash. 3 out of 5 times tested, it crashed source. --Steamfraiser 07:52, 2 Jun 2006 (PDT)
**Here it doesn't crash but for some reason it closes HL2EP1 (I see Windows again) and then the game is restarted and the trailer is shown? --dutchmega 09:03, 2 Jun 2006 (PDT)
***I'm getting a restart to a completely black HL2 screen. Nothing happens. --Alph Tech STUART 16:21, 2 Jun 2006 (PDT)
***Mine actually physically crashes, I get a "HL2.exe has encountered a problem and needs to close" then nothing opens back up. It's okay though, because the trailer was extracted to my PC and I watched it there :D --Steamfraiser 14:03, 2 Jun 2006 (PDT)
*Maybe something linked to this?
*The trailer pixelates, and chops in res under 1280, such as 1024, and 800.
**The trailer causes windows to start up and the trailer to play, it glitches (lag) when Eli starts to talk, the same happens when I play the actual file in C:\(user name)\half-life 2 episode one\episodic\media. Maybe the file got corrupted upon download, a common problem with video files.--Deadity 06:37, 6 Jun 2006 (PDT)
*Always locks my system (P4 2.4, 1GB, ATI X850 Pro), the only way I can view the Episode 2 vid is to play it from the media folder. Noticed the other videos are all 1280x720 but Ep2_Teaser.wmv is 1280x960. Even from a fresh boot with all other apps shutdown my sys stops responding when that video level fails to load. --wisemx 05:57, 7 Jun 2006 (PDT)
