Half-Life 2 Capture the Flag brings the familiar Capture the Flag game to HL2. It pits the Rebels against the Combine in a fast-paced battle over the flags within the graphics rich environment of the Source engine.

The mod is an homage to the fast-paced run and gun style of CTF and includes many familiar features found in other capture the flag modifications.

We want to make this mod the best CTF game around, so head over to www.hl2ctf.com to download the mod and let us know what you think! You can now join our new forums at forums.hl2ctf.net and let us know what you think of the latest release!

4 comments by MeNtHoL on Jan 13th, 2014

As of October 2013 Steam updated to the new Steampipe format which causes clients attempting to connect to a non-Steampipe server to receive the "Steam Validation" error. Servers must update to the new Steampipe format to restore compatibility with the mod.

Due to this update, server admins will only be able to run dedicated servers on Windows as support for the 2006 SDK has not be released for Linux and may be dropped. Many of the current servers (most of which were Linux-based servers) unfortunately had to be dropped. The remaining servers running under Windows should now be updated to the new Steampipe format.

If you are running or would like to run a Windows server, we are updating the website with the latest information on how to setup a Windows-based dedicated server on the website.

The mod suffered a couple set-backs since last Summer (Steam server browser and the new Steampipe system) which have both been resolved. We have been announcing events in both the Steam HL2CTF Group as well as the HL2CTF Facebook Group. Joining either one or both of those will help you to catch the scheduled events. Lots of games have been organized over the last week.

The October update to the new Steampipe file format requires server admins to update. The mod does not require any updates, players will have to wait for server admins to update their HL2CTF servers to the new Steampipe format.
