We've launched a new project - Half-Life Wiki. The goal of this project is to build the most complete knowledge base on everything related to Half-Life. Every member of our site can take part in developing the project.
The main goal of the project is to collect the entire body of knowledge related to Half-Life. We plan to add complete and highly informative material, for example game secrets, map tricks, information about maps, all sorts of information about multiplayer and singleplayer mods, information about plugins and add-ons, binds, aliases, information about tournaments, clans and so on.
At the moment there isn't much information on the Wiki, but anyone who wants to can help develop the new project and add some information.
Note! If you decide to add information from other sites, be sure to include a link to the source. We don't plagiarize; we're building a knowledge base that may be useful later to other players and to our community.
