I downloaded a really cool map today from Active9 Studio's called Hill 112.
They say it took 3 months to make and I believe it. The textures are great and the sound effects are awesome. Shooting, shells flying overhead, birds, etc. Looks like a great map to play. Theyre putting it on the DeathTrap Server to be played. Have to try out this 31 MB rar file.
