Cult classic is world shaker

Every week, dndclassics.com releases another helping of historical handbooks and modules in .pdf form, and every week, I eagerly hoover up the "basic"/1e/2e ones our group didn't use back in the day. I tend to ignore the 3e/3.5e material, as I find that era as dull as the corresponding brown and grey covers. There was just something magical about the TSR of old. Example: "Earthshaker!" (1985), a companion-level adventure about a titanic steam-powered automaton - four football fields in height and housing its own community - that comes stomping into the players' kingdom, causing all manner of chaos.
