Semi-active

The Semi-active designation is given to any guided weapon that requires extra user input to ensure that it will hit its target. Currently, the Longbow is the only weapon to possess this functionality, although the Yumi did spend some time in this category as well, before it was updated to Fire and Forget.

A semi active missile generally requires that the user keeps the target inside their lock-on cone for a certain duration. If player lock is broken, the projectile will either cease to track its target and miss, or self-destruct. The old version of the Yumi would require that the player stay on target until collision, while the Longbow only requires this until the missile streaks off in its second stage. Switching weapons does not break a semi-active lock-on.
