Like most Taito shooters the first level is pretty easy-going, and actually rather dull feature-wise.. just a few tanks and gun emplacements and mini-bosses in the desert..

Here's one of the mini-bosses on the left, a mobile gun-turret.. emerging from a bunker 'Flying Shark' style. It's about to be napalmed by the way...

Another mid-level boss crossing a pre-fab bridge thingy. Note the coin-pickups- these add to your main gun's firepower guage at the top-left of the screen

..which srings us nicely to the stage boss ;) Looks like a big Colt six-shooter mounted on tank tracks. The gun-barrel tracks your ship rather alarmingly. Mind the disturbingly large projectiles it flings out..

Decided to use my napalm bomb thing
here to fry it once and for all.

..which causes a most satisfying explosion effect when the payload hits home. OK first level done.. let's get on with Stage 2..
