Exactly what the title says - either as upgrade for ordinary rocket launcher or as separate item/ammo sold by Cyborg npc. Guided rockets follow the cursor (flying around it when it stays still, much like raven pet around the player), homing rockets home on the closest target or must me locked on it first.
Also I think there should be stationary homing missile launcher - much like cannon, but before shooting a missile it locks on the target.
