Please use this repository to report bugs and feature requests for Half-Life 1 related products.

If you encounter an issue while using Half-Life 1 games, first search the issue list to see if it has already been reported. Include closed issues in your search.

If it has not been reported, create a new issue with at least the following information:

• a short, descriptive title;
• a detailed description of the issue, including any output from the command line;
• steps for reproducing the issue;
• your system information.*; and
• the version output from the in‐game console.

Please place logs either in a code block (press M in your browser for a GFM cheat sheet) or a gist.

* The preferred and easiest way to get this information is from Steam's Hardware Information viewer from the menu (Help -> System Information). Once your information appears: right-click within the dialog, choose Select All, right-click again, and then choose Copy. Paste this information into your report, preferably in a code block.

There are basic rules of conduct that should be followed at all times by everyone participating in the discussions. While this is generally a relaxed environment, please remember the following:

• Do not insult, harass, or demean anyone.
• Do not intentionally multi-post an issue.
• Do not use ALL CAPS when creating an issue report.
• Do not repeatedly update an open issue remarking that the issue persists.

Remember: Just because the issue you reported was reported here does not mean that it is an issue with Half-Life. As well, should your issue not be resolved immediately, it does not mean that a resolution is not being researched or tested. Patience is always appreciated.
