It's the Martian Nomad Caverns, there's this crater with pedestals that have forcefields mounted in their heads, at all kinds of different angles. Looks like it's a puzzler requiring you to bounce your laser to and fro as many of them as possible. The "Builder Icon" key is trapped inside of these fields.

'Cept I just cannot work it out. I've got SOD ALL patience for puzzles in games to start with! :D I wasn't expecting this kind of crap in Descent 3! After about 50 minutes of hair tearing frustration shooting left, right and centre at these damn forcefields I've rage quit! :D With nearly the same great fury and avengeance as with "Commandos" :D

And for some unknown reason a timer counting down from 60 keeps appearing.....

Anyone tell me exactly what to do - total spoilers welcome - you can't "spoil" a puzzler for me! :D I HATE them!!!!!

If I remember correctly you have to fly through the force fields in order. They go out after you have gone through the correct one.

That might explain the one pedestal that didnt have a field! :D
Do they all reset after a time? (Hence the 60 second countdown that appears)

Shit! I don't like the sound of that Humonculus!!!!! :D
