Basically, in the beginning there was EiR and it was good. But then the development team got burned out and quit back in April and they never released version 2.0 which was supposed to add British/PE, add a warmap, add more role-playing elements, etc.
So, about a month ago some of the veteran members of the community (Salan, Unkn0wn, me, Draygon, Catinhat, GamerAndy, APEX, and DaysofWar) decided to launch a community-run campaign that would add more roleplaying aspects to the game and also create interesting special rule situations to spice up the gameplay. Thus "The Last Stand" (TLS) was born.
TLS isn't really a mod mod, because it doesn't change anything in EiR. It instead adds a warmap and a campaign element to the game.
Our eventual goal is to be able to do more with editing the actual EiR game itself, but that is something for the future.
In the meantime, if you head over to
www.laststandmod.com you can sign up and choose a side to start playing.
I recommend you tell people you are new and then play a few 1v1 games first to get the hang of it.
