This baby, designed by yours truly, delivers the ultimate one-two punch: you fire the timed mine first, and while you wait for the five-second fuse to tick down, you send anything dumb enough to approach you flying backward into the explosive's radius. With a little luck and some crowd control skill you'll be taking out four or five enemies with every explosion. Upgrade the clip size so you can keep this cycle going without having to reload.
