Aurail (set 1, Japan, FD1089A 317-0167)

Mastering Aurail (Japan set 1) starts with learning its core control scheme first: use the 8-way joystick to move your fighter across the screen, the first action button to fire your primary weapon, and the second button to launch homing missiles. First, prioritize upgrading your primary weapon early: red “P” power-ups dropped by special enemy fighters raise your shot level up to a maximum of 3, with each level adding extra bullet streams and increased fire rate. Hold down the primary fire button for 2 seconds to charge a piercing beam that can cut through multiple enemies and destroy armored ground turrets in one hit, a trick that will save you from heavy damage in the first three surface stages. For stage 4 and beyond, which take place in Aurail’s underground tunnel network, watch for fast-moving enemy craft that spawn from the left and right edges of the screen — save your charged beams for these swarms, as regular spread shots often miss fast targets. When facing boss encounters, always target their weak points first: the first stage’s flying fortress boss has a glowing red core on its undercarriage that only exposes itself right before it fires a wide laser barrage, so position yourself below it and unload charged shots and missiles during that window. Don’t risk picking up power-ups if they are surrounded by heavy enemy fire, as losing a life resets your weapon level to 1, which makes subsequent stages far harder. For a hidden bonus, shoot the large rock formation in the top-right corner of stage 2 to reveal a 1-Up extra life, which will help you conserve continues for the final two high-difficulty stages. Note that this Japanese version has slightly higher enemy spawn rates and denser bullet patterns than the international release, so avoid rushing through stages and focus on evasion over scoring if you want to reach the final boss.
