Hot diggity, this game is sweet. Really difficult, but awesome. And I agree with what the others've said. Need upgrades and/or plane choice to make the later levels a little easier. I'm suck on '47 meself.
It's pretty good. I think my only complaint is that it's pretty monotonous (because there's little change other than the background) and the stages are ridiculously long...
Excellent game, better than all the last. I liked how there were pretty much 12 missions in each campaign instead of 6 like in the previous games... Also, being Finnish, I had a good time shooting at those Commies... And a good time shooting at Finns too, XD
Superb except for some bugginess. Usually when I finish a level, it skips past the Fizzy Games screen and doesn't load the next one. I'm stuck on the night sky and leaves.
The only thing I don't like is the fact that so much has to do with luck... If you jump onto a small roof, and then a bomb falls, you have to jump over it and often jump into the gap between a building...
