Officially, this is not possible, if you want to do something like
"return to GRUB". Before a multiboot kernel is started, the state of
GRUB 2 is destroyed.
One solution might be switching back to real-mode, making sure the
computer is in a normal state (graphics, IRQs, memory, hardware, etc).
In that case you can just load GRUB 2 from disk and jump to it.
An alternative solution is, if the license for the game is GPLv3,
making it a GRUB 2 module ;-)
