Strf 9040 BILL Launcher can't aim up

Hello. Is it just me or Launcher on strf 9040 BILL cant aim up or down (in other words cant move at all).
Idk if its a bug, or it was done like tat on purpose.

It used to be able to aim according to your internal aim with the gun, to some extent, but since there are lacking information of this feature the devs removed it a while back. If you do have information about the specific features of the launcher itself it would be nice to share :)

In other words we dont know if it actually could aim up and down.
