Earth Defense Force: Insect Armageddon
Earth Defense Force is all about blasting skyscraper-sized bugs and robots with ridiculous weapons. If you think that premise sounds like it was inspired by old-school Japanese monster movies, you're right. The latest trailer for the game reinforces that connection because...well, it's in Japanese.
Keep in mind that this shift in language isn't some stylish callback to the game's roots...this is actually a trailer for the Japanese audience. So, don't worry if you feel like you're missing the joke or something.
