Did you play Supreme Commander/Forged Alliance? Did you like the path finding? Did it want to make you kill yourself? Trouble yourself no more!
In Supreme Commander 2 we will have a state-of-the-art path finding system called Flowfield. It does exactly what it sounds like, it makes the units "flow" around each other in a very impressive way. This will make micromanaging a dream, since units won't play bumper cars with each other as soon as you want them to blow up a few hostile mexes!
I personally find myself very impressed by this system and hope that the rest of the game will be as impressive!
