No and probably not. I don't remember testing beams. I believe the collision location is already calculated in the code itself, but there's no scripting access to the variable.

Check your PMs. :D

load up some infyrnos. use the mouse to steer them. :D

Can you release them when they are locked on, like in descent (press fire button again, and they home like normal).

Nuke:
you could do that with weapon children and remote-detonate. you can pretty much use this on any non-homing missile, homing ones work but are abit jumpy. you can even use primaries but it tends to screw up their collosions.

Cobra:
Ooh! OOH! Do the Helios! :D
