ADD BOTS PLEASE!!! I've been tired of never being able to play such a great game because nobody has heard of this mod. Bots are a great thing added to many sucesfull valve multiplayer games like Team Fortress 2, Counter-Strike series, etc. I hope that you eventually add bots to the game. You guys are doing great work. Please do the whole + vote thing if you agree.

Hopefully, you guys are making progress. I've been waiting upwards of 3 years for an update. Would be nice to know at least how far along you guys are so we know how much longer we have to wait v.v
I have access to their SVN/Dev version of the update they are working on (I did their website which no one decided to keep paying for lol). And trust me, work continues actually a little more rapidly than usual. They picked up some experienced coders (which was what has been stalling them for a very long time now) and Im seeing a lot of progress again. And if your an old player you should redownload the mod and give it another try as is. I'll admit is not a Battlefield 3 quality, but its fun quality can be a lot of fun sometimes. And TRUST me, if it were not for a few of us who stuck around through this mods very short fame it got when it released, we wouldnt be sitting here talking about this MASSIVE update about to happen. Show your support by helping the fan base grow by having players in game when they first download and try out WW1 Source. Im not taking much stock in the thousands of players who we saw come and go during the mods initial release almost 3 years ago to be that reliable again after 2.0 comes out.
They are making progress. You may have a few months to wait, but just play the game as it is until that time comes. I personally love it as-is.
This mod is very interesting, I would hate to see it die there's barely any WW1 games.
Trust me, it's not dead. The dev's are hard at work putting it together.
