The arena takes place in a museum.
The platform is in stone and arounded by heavy fences. There's an exit on the plateform with a the logo of the museum section : "The Last of Dinosaurs". The logo represent the skull of a tyrannosaur.
The platform is eleved above a void where three dinosaurs with limited movements (maybe animatronics) come out. There a a Tyrannosaur, a Triceratops and a Brachiosaurus.
Behind the dinosaurs, another section of the museum is visible, it seems to be a painting section.
Finally, some windows show the city at night.
