Homing Projectile
A projectile or attack in interactive media (or a narrative description in non-interactive media) that homes in on its intended target. If you're firing it, it can be an effective means of eliminating targets without putting yourself in harm's way. If an enemy is firing it, you'll need to perform a High-Speed Missile Dodge, whip out a shield, trick its guidance system, Shoot the Bullet, or just outrun it until it loses steam.
A curious trait of most homing attacks is their inability to "lead" a moving target, resulting in them doggedly "trailing" behind if the target can move fast enough. Very few homing attacks will actually plot an intercept course on a moving target.
A fairly common projectile type in Shmups and Tabletop Games.
Subtropes include
- Action Bomb in which the projectile in question doesn’t fly.
- Boomerang Comeback in which the projectile starts homing after overtaking the target
- Precision-Guided Boomerang no matter what
- Homing Boulders in which the mechanic is there but doesn't make sense for the situation, such as boulders rolling at you that home in on your location.
- Macross Missile Massacre in which a huge, ominous cloud of homing missiles is released.
- Roboteching in which the projectiles don't start homing until after they've flown a fair distance.
- Pinball Projectile in which the projectiles move by bouncing off of non-targets.
- Reflecting Laser even if the projectile is a laser beam
- Super-Persistent Missile in which the projectile not only guides itself toward a target but doesn’t give up if it misses.
