One of the most original and creative Half-Life mods out there. This mod is based on the Revolutionary war. It is realistic, taking between 1-3 shots to kill a person, however usually 1 or 2. It is also realistic in the sense that you can only fire once before you need to reload, however, they make it work well. You can find "The Battle Grounds" at www.bgmod.com
DUDE! BG is the best HL mod I've ever played!
