Mondkalb has release his new Window Of Opportunity (WOO) game mode on the BI Forums.
Window Of Opportunity (WOO) is a new game mode that is basically a mix between warfare and high command. More commonly known as "Real Time Strategy".
Goal of this was to create a new gamemode that appeals to all of those players, that couldn't get around playing Arma2 anymore because of the lack of fellow players to help get a decent sized coop squad up, to those that have constant performance issues when playing and those that think Arma2 can be played in a bigger magnitude, with a bigger scope than a normal coop or warfare offers.
And, without being modest, I believe I've achieved all that.
So, go ahead and have a try, because describing what it is will inevitably lead to TL;DR. (Or check this video out, first.)
