Leviathyn.com | I know the EDF series isn’t for everyone. Some may be put off by the simplistic graphic style and some may not like sci-fi themed games. Personally speaking, Earth Defense Force is one of my all-time favorite series. I love everything about it. Some might say that I like it because it’s supposed to be over the top cheesy and just all out ridiculous. This is not the case. I find EDF one of the most well developed games out there.
