Game on ns_origin: Marines are pretty much going down, so we're pushing for Furnace, hoping that we can take at least one hive down. We're in a five-man train with shotguns. Two fades start harrassing us from either side, but we eventually push into the Smelting Room, which has two lava pits with complementary lava falls.
We push into the main doorway, chasing down a fade - DM. He starts hitting us, but we fire in his back around two or three times. Half a shotgun blast clips him on the side as he blinks through the doorway, back into Smelting Room, so we chase him down. I get a shot on him, but he still doesn't go down.
Then, he jumps INTO a lava pit. He doesn't jump through the lava flow, he just up and jumps into the pit, like you'd dive into a pool. A second later, he pops right up, like something you'd see in a movie. I get one more shot on him, but he still doesn't die. He proceeds to blink away into the sunset.
I think DM is either awesome or lucky.
