I haven't read the graphic novel for PacRim (and I'm planning to once I find a copy of it) so I'm not entirely sure if there has been any mention. But I did notice in the movie that the United Kingdom is actually one of the countries that funds the Jaeger Project/Program (at least, under the flag of the UN) despite it being on the other side of the Atlantic. Did the UK ever have any other involvement in the program or any other mention that might be relevant to the verse or the game?
