I don’t know much about Maschinen Krieger as a game (it’s apparently a table-top far-future retelling of WWII, with less tanks and more robots), but boy do the people that play it make some incredibly detailed, good looking miniatures. This spider-bot, called ‘Neuspinne,’ isn’t exactly from a kit, but is instead hand-crafted from parts from other kits—something that seems to be the norm among the Maschinen Krieger devotees. There are tons of great mecha and powersuit designs on this guy’s page, as well as links to many other related sites. It doesn’t get much more evil than a Fascist probe droid. (Thanks, Rob!)
Update: Looks like we hammered his site, so at the author/creator’s request I’ve pulled the link.
