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 duke 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.
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.
