Today is the day in which PC players can fight to save Earth from giant alien insects. That's right, Earth Defense Force 5 is now available on PC via Steam. It's published by D3PUBLISHER Inc. and developed by SANDLOT. The game is currently on sale for 20% off for its launch, making it just $47.99 (regular $59.99) until July 18.
There is also a bunch of DLC available, if you're into that sort of thing. Some of the DLC is more cosmetic in nature while some of it does give you a small advantage on the battlefield in the early stages...
