Download: Client Alpha v0.27. SHA1sum: 9dc0af162fc68b7d483435ab0fab0d2a4c96ad19

Requires HL2 with HL2DM to play. Once you've installed HL2DM, then download and place AoA in your Half-Life 2 SourceMods directory.

If you just want to play the game, you only need the client download listed above. However, if you're looking here for server files to download, you will instead want to send a server hosting request.

Site hosts: You may mirror the client files. However you must send a note indicating you are doing so.
