Fight on all fronts, but only as Allied forces. You can fly German aircraft on single missions, but not in campaign mode.
For me it is one of the best PS3 flight combat sims out there, ranging from arcade mode to realistic to actual simulator mode.
Endless hours of flying fun and when you up for it (and finished the campaigns on arcade) go to harder mode, where limited fuel and ammo gives you the more realistic feel of back then.
Sadly for me though, no axis campaigns available
