Welcome to One Eyed Jacks: Half-Life / Opposing Force website.
The servers have a vast amount of custom maps including some familiar Half-Life maps and Opposing Force maps.
These servers are UK based and also have fast downloading enabled so that all of the server files will be loaded onto your system in a matter of seconds.
I am always open for suggestions on how to improve these servers, if you have any suggestions please post a message on the Steam group which you can find by clicking here or join us on discord by clicking here.
