yes, in headshoots (from what i understand) their god-like avatar of destruction was able to weild a handbag and decimate sieges alone...clad in a artifact adamantine breastplate thats so covered in blood and gore its permamently stained the colors...not to mention SHE was increbile insane and powerful.
Now that I have a bit more time to get wordy.
First off, I'm pretty sure it was a backpack. Could be wrong, but I believe.
Second, it used the old skill+stat progression system. Gaining any kind of skills improved a dwarf's strength, toughness, and agility, so dwarves with extremely high skills also had godlike stats to go with them. HolisticDetective didn't have god-tier weapon skills since she spent most of her time wielding her backpack (another old bug that I believe went away with the new military systems), but the other superchampion at least was a blademaster several dozen times over and had VG-tier physical stats as a result.
Third, the wounding system was much, much more abstract back then. Stories like someone throwing a fluffy wambler and critting a bronze colossus's head off happened because critical hits did silly stuff back then. A single bolt could hit you and obliterate every organ in your body. But if something didn't crit and actually damage you it basically didn't do anything if you had armor. Between the new stat system no longer giving high-skill dwarves Wolverine-level endurance and the new wounding system making hits more dangerous, the chances of any dwarf doing the kind of stuff that the Headshoots champions did much, much lower. (The VG, in either incarnation, would probably be turned into cat chow in a straight fight with HolisticDetective.)
Fourth, damage systems were rewritten as well. Toady coded a system that takes into account concepts like the weapon's hardness, how well it makes a blade, and its density; this is why a silver shortsword is worthless and a silver warhammer will cave in a dragon's skull, because silver makes a horrible edge but is really ninjaflippin' heavy, and candy makes a terrific blade (because it's super sharp) but a horrible mace (because it's about as heavy as styrofoam). In theory, improvised weapons like HD's backpack would be fairly weak under the new system.
Times change, I suppose. One could mourn the loss of Headshoots-style demigod champions or Boatmurdered-style elephant hordes and world-destroying magma cannons.
(On the other hand, times do change for the better, too, because you couldn't build minecart railguns in Headshoots, either.)
So, my suggestion for a mega project: Would a "train moat" work? Set up a track enabling us to send minecarts onto a circular track that goes around the Murdermachines walls and rig booster track to it in places, using either a BATTEREY device or a windmill farm to power it. Add minecarts to it so that they can circle it eternally, perhaps loaded with stones or giant buzzsaw blades. Hmm.
