I still don't know what it is.
A
scarab is a giant spider like vehicle used by the covenant. It is
extremely large and slow and has 2 big cannons mounted on its head area and on it's back. There are usually 10 covenant ailens on board ranging from brute to elite to grunt. The only way that I am aware of destroying it is to throw some sticky grenades at the
central core.You can slow it's progress down by attacking the
4 weak points on it's legs, causing it to come crashing to the ground.
From there you can climb on to it's
small walkways and passages and find the core and destroy it.
My brown townaysis shows that you would need an extremly complicated bounding box for this vehicle, and a model that is
almost impossible to re-createBTW, this goes in suggestions
