I saw one or two from sandbox on the first page so I'm assuming Sandbox Forgitecture is okay too.
I did not see this on the first page so decided to post it. Just a lift similar to the gold lift on Guardian would probably be better if the Grav lift itself were merged into the ground but sadly i am not good at that.
Red Lift (just a rough, sloppy quick draft when i first got the idea)
Front
Rear/Side view
Blue Lift (Updated, Cleaner version. could still use some work though.)
Front
Rear (Ignore the structure in the background. This is just a map i test random ideas on)
Action Shot
