Awesome mod !

such a good game reminds me of the Trenches mod for HL1 i loved that mod :D

Fun to play

While I'm typing this,I hear It's A Long, Long Way To Tipperary trough my mind.

Good mod. I played this when I first came out,I never
saw I game before who made such a good and fast progress.
The graphics are 10 times better then I few months ago,I especially
like the realism mode where you almost feel how both Allied and Central soldiers had to feel in the trenches back in the first World War

My great grandfather was an Allied (Belgian) Cavalryman ;-)

Probably one of the best mods out there, next to Zombie Master. One of the funnest mods I have, and will always be playing it when I can :D

Very difficult to operate weapons and utilize controls
