Half-Life: Alyx Commemorative Patch
City 17 is a patch from the Half-Life: Alyx Patch Pack container introduced on 22nd March 2020 as part of the release of Valve's virtual reality video game - Half-Life:Alyx.
The patch depicts the logo of City 17 which first appeared in Half-Life 2. The city was the only location in Half-Life 2: Episode One. The location returns in the latest installment - Half-Life: Alyx.
This patch can be applied to one of three specific locations on each agent, and you can apply more than one for each agent.
Patches can be removed from an agent but the patch is destroyed when removed similar to a sticker after scraping it too many times.
