It sounds like a good idea: co-operative missions, heroes, a fresh setting. But Worldshift fails, mainly because of bad design that ignores the standards of the genre. Having to control every single soldier manually because there are no group controls isn't acceptable. Different heights, trees, houses and even whole rock formations are ignored or can be shot through. The three factions are well balanced for multiplayer, but the single player campaign basically consists of "go from A to B" and "try and error". Even the best ideas won't work if you get the basics wrong. Maybe it's better to wait until Black Sea has ironed out the problems.
