- TRIVIA -
Released in March 1988 in Japan.
- UPDATES -
In the non-Japanese version (set 1 in MAME), the dipswitch for coin A corresponds to what is typically the left coin input, and dipswitch B corresponds to the right.
In the Japanese version (set 2 in MAME), the dipswitches are swapped, so that dipswitch B corresponds to the left coin, and A to the right. The 1st set also does not display the Japanese warning screen.
- TIPS AND TRICKS -
* Double Bonus : When the big flying ship comes (the one in 4 pieces) that gives you one bonus for each player, fire repeatedly on the second piece before it is in place. If it is destroyed before it is in place, you will be given two bonuses per player instead of one.
* At the end of level 5 : When you arrive to the final enemy, around the hand pointing up of the statue there are two hidden icons. You can fire up with the jeep (or diagonal with the chopper), and you will see that your shots gets stopped by something invisible. If you keep firing, finally two new icons will appear (of course you don't have to kill the final enemy). Take this icon, and you will have a bonus. The bonus depends on your rank. If you have the Eagle rank you will earn 500,000 bonus points. If you don't have it, then you will earn 100,000 bonus points and the Eagle rank.
