Lock-On

Lock-On is a 1986 first-person shooter and combat flight simulator video game with a futuristic theme. It is developed by Tatsumi and licensed to Data East for US distribution. Its graphics feature scaling sprites and a full-screen rotation effect. The game consists of 20 levels. Gameplay is similar to After Burner, i.e., the plane follows a predefined path, but the player can steer it slightly to evade incoming missiles. The player can fire guns and homing missiles, the latter of which requires the eponymous lock-on first. Source: Wikipedia, "Lock-On (video game)", available under the CC-BY-SA License.
