• 04/23/2012: The host of the server that ApolloRP.org was on was attacked several days ago, and unfortunately everything was lost. No backups are available as I lost them last time we switched servers, which was fairly recently, and I didn't get a chance to get automatic backups started again. For the record, we had something like 500 members, 20,000 posts and have existed since 2006.

Apollo RP is a mod for Half-Life which modifies the game world to be closer to a role-playing game. That is, it establishes a virtual economy, allows players to use items that have real effects in the game, and other things that make the game more than just a first-person shooter.

• Economy - Features a fully functional economy, with the ability to manage items and money in a virtual game world.
• Non-Player Characters (NPCs) - Characters with AI who participate in the game environment can be added onto a map to enhance the experience and make items and services available to players.
• Properties and Residences - A large system exists to allow players to own properties that they can manage and give people access to. Every door to a property is independently managed, and keys can be given to any trusted friends. Properties can range from anything from a gang's hideout to an apartment.
• Jobs - Players can either automatically get a job or be assigned one by an admin. A job can just be a title, or it can be something a player actually has to go do. They are paid an adjustable salary at a regular interval.
• Realism - Some realism features exist as part of the base package, such as hunger and the need to satisfy it with food items. Others realism features are available through plugins written for Apollo RP.
• Access Control - A fully functional in-game administration system exists. This can be used to restrict access to players for certain features and abilities. This access control system can also be used to automatically give all members of an organization access to a property, among many other things.
• Robbing - A full system for simulating robberies of non-player characters exists. This system can also be extended to do other things as it is extremely flexible. For example, it can be scripted to act as a house alarm or a disco ball.
• Jail Mod and Cuffing - Players can be subdued by police and thrown in jail. This opens up chances for roleplaying, and creates a greater sense of realism with a more clearly defined cost-reward of any activity, especially illegal ones.
• Saving to SQL - Everything is saved to SQL, so if a server crashes or goes down, it can easily return to where it was. Servers can also easily be linked so that they run on the same economy but different maps.
• ... and best of all, a great API - The most notable part of Apollo RP is its extensive API. Almost every function within it is exposed to plugins so that they can alter or extend functionality.
