Sometimes I swear, on all that is holy, I see my anti-ship drone shoot an enemy laser out of the air as it leaves its gun. This is similar to how a Defense Drone Mark 2 will shoot lasers out of the air same as missiles, except it happens on the ENEMY SHIP side of the screen rather than the FRIENDLY SHIP side. Has anyone else ever noticed this?
Weapon collisions exist in the FTL. They're very unlikely, but they can happen. The projectiles and even drones from opposing factions can annihilate each other, as can asteroids.
This is a contrast to Defense Drone, whose role is to shoot down Missiles, Boarding Drones, and Asteroids. It's a further contrast to the Defense Drone Mark II, that can shoot down incoming lasers.
