Player's Life

• When the player collides with enemy aircraft or enemy bullets the life gauge will decrease.
• When the life gauge is empty your game is over.
• When your life is not full you can continuously shoot ground targets to obtain recovery hearts.
• Obtaining a recovery heart restores partial life but with the penalty that the hit combo is reset and the number of medals obtained is reduced.

Elements of Scoring

• In Battle AirForce the player earns "Shooting Points" by shooting enemies with the autocannon, "Bullet Erase Points" by canceling enemy bullets, and "Bonus Points" from medal acquisitions.
• Shooting Points = number of medals acquired x 30 + number of HIT combos x 10 points
• Bonus Points = number of HIT combos x 10 points
• Bullet Erase Points = number of HIT combos x 10 + number of medal acquired x 10
• When adding the Shooting and Bonus points to the score, their added values are attenuated linearly depending on the amount of laser charge.
• Shooting Points is not added while the laser is being fired.
• The number of medals you get decreases as you fire lasers or as your life gauge decreases.
• The number of HIT combos is continuously added by firing shots and lasers within 60 frames (about 1 second) or by acquiring medals, up to a maximum of 9999 HITs on display.
• Medals are automatically tracked when you are in proximity.
• If the HIT combo number is over 1000, the medal will be auto-tracked from the beginning.
• Aim for a high score by maintaining the number of HIT combos while obtaining medals as long as possible.

Simple score increase guidelines

• When combos and medals are low, you aggressively use lasers to try to increase combos and medals.
• When combos and medals are high, you shoot lasers as little as possible to score points.
