LISTEN TO ME, HERE ME OUT! One and All, great and small!
I think there should be a little revival of this weapon and make the fired projectile hit a surface and light it on fire, while rebounding into a subtle trajectory similar to how the grenade launcher (hand weapon) bounces off walls. That way it then has a second chance to deliver damage and could be used deliberately to hit FT team members on a reflective shot (like in a game of billiards) AND still hiding the predators location.
Now this could be as i stated it above,
or it could use a guided holographic visual to show you where it would go.
