Besides the undead, Return To Castle Wolfenstein also has some great monsters built by science. The Loper is some ridiculous monstrosity with no legs, walking on its arms, blasting arcs of lightning at you (and everyone else) with its tesla coil device.
These guys are complete dicks, they jump around and lunge at you, and their thunderbolts have ridiculous range, they can kill you pretty quick and are kind of good at dodging. The upside is that they are completely feral and will zap whatever Nazi troopers or scientists it finds just as well as it'll zap you. I find the weapon that works the best on them is the Flamethrower, mostly because you can douse them with a charge of flaming fuel, and then run and hide so they can't zap you, as they burn away and perish. Trying to face them in a regular gunfight I feel is not worth it as they'll almost certainly take more than half your health in exchange, they're too fast for grenades, and blasting them with a Panzerfaust I feel is wasteful.
I really like how these guys look mean as hell, and definitely live up to it. Great monster, and it's almost a shame you only get to face them in one level.
