Being a part of the Earth Defense Force is no easy job. While most people just see giant bugs and robots leveling their hometowns, the EDF needs to identify the different breeds of the planet's extraterrestrial attackers. Thankfully, Insect Armageddon publisher D3 has provided a handy study guide.

The PlayStation Blog has an extensive look at the creatures you'll be sending back home to space in the upcoming title. It's a great read for EDF fans, providing details on the various ants, spiders, ticks, and robots you'll have to eradicate when the game hits shelves on July 5.

Now you'll never be caught on the battlefield not knowing the difference between a wolf spider and a bomber spider...though the strategy for defeating them both probably involves a lot of shooting. EDF! EDF!
