Unlock skins

[Pumpgunner]

Since the levels are getting really hard for me after 40 (for normal and advanced) I just want to aks you guys if there is any method to unlock the skins.

Or are there any save games which I could use?

Are you still interested in a savegame? I've unlocked all skins except one and got all medals...

speaking of save files, where is the save file located? ive been looking for it to backup but cant find it...

Hey, if you're still around I wouldn't mind a save file, please.
