Report Bugs Here / Known Issues
Found a bug? This is the place to share it, bug reports with videos or a detailed description are the most helpful so we can determine what the issue is and resolve it. Thanks!

This thread contains map spoilers.

Known Issues:
  • Ammo will not spawn on the Jail guard if the player has enabled a custom weapon addon. To progress you'll need to wait 45 seconds for a backup magazine to spawn outside the jail cell.
  • If a physics object collides with the players head while on an elevator it will push them off the elevator (This is a bug with the engine, you'll need to reload a save to get around it)
  • Club Music - In rare cases the muffled club music never stops playing

Crashes
  • Dancefloor Combat Crash - Reloading the autosave right before the Club Dancefoor combat can sometimes result in a crash. Our best known workaround is to load an older save. Possibly fixed with V1.1, but more testing is required. If you're still running into this issue please let us know.

Fixed Issues:
  • Hands are missing after a map transition (Fixed in V1.2)
  • Combine bouncer can be killed with a traffic cone (Fixed in V1.2)
  • Loading Screen Crash (Fixed in V1.1)
  • Club doors lack collision (Fixed in V1.1)
  • Custom pistols addons no longer prevent ammo from spawning on Combine soldiers (so long as The Undertow is the most recently enabled addon)

Note: You can now play through the campaign with a custom pistol, just make sure The Undertow is the most recently enabled addon before you start the campaign.

On an Index, game crashes after the security alert in the nightclub after you fail entering the security code. The alert message pops up and the game freezes. It was a super experience up til that point. Have tried different ways around it but still stuck after 10 attempts.

somehow managed to get past the fight by staying behind the bar using a pistol.

Thanks for the detailed write up on this crash you experienced, we're still trying to determine the cause for a couple of crashes that are occurring in rare cases. Glad to hear you were able to get around it. There are two save points in the second map before this point I believe, once would be in the bathroom and the other is after you've activated the security console. Do you know which one you loaded?

Appreciate you letting us know about this issue. I experienced this once while testing the map, but I never saw the issue again. Have you tried loading the most recent save and going through the level transition a second time? I'd be curious to know if this crash is consistent for you.

I restarted the game using only the pistol the one time that I got past the security alert in the bar scene. I can't recall which other "saved game" that I used but presume that I had used the most recent auto save. Thanks for the quick response. The game is a blast!

I had this same problem. I loaded a save from before I got to the bathroom and it stopped happening and I was able to progress.

The only other crash I had was after two fails on the dancefloor at the end. I died twice and then it CTD.

Managed to trap myself above the elevator when it falls
was moving around a-lot and could have jumped when it started falling

Thanks for reporting this. Do you have a controller binding that allows you to jump in air? Elevators are fairly buggy in the base game so I'm not surprised this happened. Were you able to load a save and progress past this point in the map on the next go?

this may just be on my part, but during the fight using the vort energy of just nothing but the same certain enemy (ones that own a shield) when there is three out there, my game crashes every time. tried a total of three times and everything else did work just fine! my renders and settings are at their lowest.

Thanks for the crash report, sent you a friend request if you're up for discussing further. If possible it'd be great to get your save file so I can see if I can reproduce the issue on my end. Some people online have reported that HLA crashes less when you have the game minimzed on your monitor, so that might be one workaround to try.

unfortunately loading map 2 with the console command still crashes upon loading. was there any other potential fixes found for this? maybe i gotta do a second playthrough? cheers

Hi Sensational, after doing some more testing I think the issue is that Map 2 is simply too large for some people's machines to handle. I'm currently testing out a smaller version of map 2, sent you a friend request if you're up for trying it out. Would be really helpful to see if it works on your machine.

HP Reverb G2 left hand motion controller cannot grip, retrieve or pick-up ammo / item or use gravity glove. I looked at the Steam bindings and they all appear correct and the same for both controllers. In short I can't load my gun unless I place it in left hand, but I'm a righty! Thanks MG

Thanks for the detailed report, there's no map logic that I'm aware of that would cause this. Have you checked to see if this issue happens in the HLA campaign or other add-ons? I'm also wondering if there's a SteamVR community binding for Reverb users that might fix this issue.

Edit: I found this thread Reverb controller issues, I'm wondering if it's the same issue? Thread has a workaround for it you can try.
