====================================================================== F-15 AND MAO-MAO ====================================================================== Press C-LEFT, C-DOWN, C-RIGHT, C-UP, C-LEFT, C-RIGHT, C-DOWN when "Press Start" appears on the opening screen. A hidden F-15 with a female pilot (Mao Mao) can now be accessed. ====================================================================== LEVEL SELECT ====================================================================== Press UP, C-DOWN, LEFT, C-RIGHT, DOWN, C-UP, RIGHT, C-LEFT, L, R, Z during the opening sequence when the fighters are in flight. A sound will confirm correct code entry. ====================================================================== SPANKY ====================================================================== Compete all bonus missions to access Spanky as a hidden pilot. ====================================================================== FLY ENEMY PLANES IN DEATHMATCH MODE ====================================================================== A new enemy plane will be available in deathmatch mode for each level completed during game play. A total of six enemy planes may be enabled. ====================================================================== ALTERNATE PLANE COLOR ====================================================================== Press R at the plane selection screen in main game, practice or boss attack modes. For death match mode, hold R while selecting one of the four default planes. ====================================================================== UNLIMITED CONTINUES ====================================================================== Before reaching one credit remaining, reset the game and continue from the menu that immediately follows the title screen. The game will resume with the same number of credits that were available when the current stage was started. ====================================================================== BONUS LEVEL ====================================================================== To get to the secret level, you must complete EVERY level, including the bonus levels. When you beat the Ice Cave with all other levels complete, you go to a new level - The Moon. You will have no wingman support though. ====================================================================== EXTRA PLANES IN BATTLE MODE ====================================================================== To earn six new jets, beat the first two stages to earn the MIG 25 and MIG 31, complete the third and fourth stages to earn the F-22 and KFR C2, and finish the game to earn the EFA and RAFALE. ====================================================================== SUPER SHORTCUT ====================================================================== There is a major shortcut hidden in the ice caves level (as the mission information indicates)! It is located behind the large downward bend near the beginning of the level. To reach it, fly down the cave until it gets wider. When you reach a wide enough area, turn around. Continue back, fly through the gray bars, follow the tunnel, and you will reach the boss without having to fight your way through many enemies! I also found that flying out of the cave entrance will get you shot down. You will then be placed back in the cave and seemingly not recieve any damage! ====================================================================== TOMAHAWK TRICK ====================================================================== Choose the F-14 then start a new game. While flying, use your special, missile and chaff in that order. If you did it right you'll launch five Tomahawks and four heat-seeking explosives.
