From Warlock Studio:
WW2 Tail Gunner is an arcade shooter in which you take the role of a gunner on a B17 Flying Fortress bomber for USAF or He-111 bomber for Luftwaffe. The game starts out with you already in the air and ready to shoot down the bandits who are trying to bring your bomber down. Enemy fighters will attack your bomber from all sides. Your job is to switch around all available gun positions in the plane (there are six for B-17 and five for He-111) and try to shoot these bad boys down. It's a real shoot 'em all game. You do not get any escorts, so you are pretty much on your own. 30 missions for each side (i.e. 60 in total), it doesn't sound that easy, does it? Download the game now and show what you are good for.
