Hey look buddy, I'm an Engineer. Which means I use fungus. Not fungus like weeping fungus, because that would mean I would have to get off my lazy ass to get healed. I use bustling fungus. For instance, how am I gonna stop some big mean brass contraption from tearin' me a structually superflous new behind? The answer? Use a shield. And if that don't work, use your turrets. Like this, heavy-caliber tripod-mounted little-old-number designed by me. Built, by me. And I best hope... I don't run outta fungus.
