Drumdevil's GM_Medieval_Warfare is a map about its namesake: Medieval Warfare.
One of this map's main features is the ability to spawn pre-made parts parts for things such as catapults and cannons by pressing a button, and ammunition for them such as cannonballs of varying sizes can be spawned by pressing the appropriate buttons too.
This map uses models and textures from the games Half-Life 2: Episode 1 & Episode 2, so you'll need those games to be able to use this map in its full functionality.
The map author also has a dedicated server up at the address 94.209.56.166, so be sure to check it out whenever it's up.
