or you could give the antenna about 9 animations with different combinations. Then make a script where you are shown one HUD for each comination possiblity, and the player has to enter a number for the choice he made (might be a problem with the weapons).
So if he makes a decision, the chosen animation plays and - if the combo was right - will stay and the puzzle is finished - or the whole thing collapses and you start again...
May sound complicated. So I made a pic how this could look like
BTW: Storm 6000's idea is more simple.
The Swarm of flying pigs is coming...
Killer&Slaughter Machines Pack too!
