It's simply AWESOME!


This is a mod that should be on steam.

Great mod, lots of people should be playing this stuff!

no servers :/



Best game ever.


I mean its not a pretty game, but the fast speed and solid game play of the game makes it a game that you can compare with Counter strike.


This source mod is great. The community is fantastic, with hard working devs to bring out the long awaited 2.0 . Even so, the 1.13b version is still one of the most fun games I've ever played online.


Great efforts put into the mod, a ton of work, bravo I say, 2.0 will look and be played very awesomly I can feel it! Cheers


I love this game, very fun to play, especially realisms. And for the love of God, there are servers though they are filled during weekends or weekday realisms. I love the bolting system and the Officer's Arty & Gas abilities. It makes it the same as in the real World War One. Too bad many people reject the mod because "there are no servers". Well wait for the weekend and you will enjoy it a lot :)

I don't mean to bring you down, but I found this mod pretty dreadful in its current state. Your attempt at realism by forcing the player to "pull the bolt" every time you shoot is annoying but I guess some people will like it. The Officers' ability to drop toxic gas and artilery is terrible. It's very frustrating to get killed randomly, and it adds nothing of value to the gameplay. The biggest problem I had when playing was really the red effect when you get hit. It paints nearly your entire screen…
