SourceForts is a Half Life 2: Deathmatch mod where Combine and Rebels face off in capture-the-flag action with a big twist. Players build bases and other structures with blocks and plates in the "build phase" to protect themselves and their team's flag (which is actually a ball), and then fight it out and try to capture the enemy's flag in the "combat phase". Once the combat phase has ended, it's back to build, where players can repair, improve, and change their creations to ready them for the next combat phase.

The next planned major version will introduce an entirely new style of play. The most major change is the removal of the build phase, and the introduction of capture points to the existing CTF formula. Building will still remain an essential part of the game, for the team that does not build will surely lose. As is planned, a new art style, new maps, and new models will be added as the next major release progresses.

Does this require HL2 Team Deathmatch or does portal or TF2 work?

should only require Source SDK Base 2007 to be installed (so you need at least one game using that engine: portal, tf2, hl2mp, hl2 + episodes, etc...)

The current version (1.9.4) uses Half-Life 2: Death Match. The new version (2.0) will use the SDK Base 2007 (which you can download with any of Half-Life 2, Episode 1, Episode 2, Portal or TF2).

Cool so when will 2.0 most likely be released? (I've got Portal and I want to check this game out.)

One of the best mods ever developed.
The gameplay is amazing, if you're good at building - and I'm counting myself to these people - you can create amazing uber forts.
It's a masterpice, giving people so much fun and awesome moments.
I still remember the Lans where we played it all night on our favourite server.
We'll miss you, Urban.
