The helicopter goes boom over your head as you're forced to land on top of Castle Shisenstein and make your way all the way to the basements. Can you do it?
And our third choice is <=[Shisenstein]=>, ten maps for the Second Encounter by Thomas Elgin of WolfenJunkie Software. Things start out innocuously enough: a helicopter is about to drop you down near Castle Shisenstein, where you are to steal secret plans and exfiltrate via the same route. But nope, the whole setup was a trap and the next thing you know, you find yourself on the roof of the castle, under machinegun fire, the chopper exploding ten meters above your head. So much for your airlift escape! The only way to go is inside, and as luck would have it, you suddenly find the plans in a hidden compartment when climbing a ladder down. That's more like it. With the target of your mission sitting safely in your backpack, you're standing on the top floor, ready to go all the way down and escape through the sewers. Wotta bother.
<=[Shisenstein]=> offers some interesting mapping for the most part: many secrets, some tricks, places you probably don't want to hang around too much. Lots of dogs too, at least later on. This continues for a bit, then there's a couple maps that look suspiciously like WolfMaker output, then the mod returns to form and puts you through four more rough levels. All this is presented as anything-interesting-ware: send the author *something* (even a lump of coal would do) to receive registration bonuses, including First Encounter scenarios: *-={(|Draconstein|)}=-* (10 levels) and Hell Dogz (8 levels). But these scenarios don't seem to be available, so I guess nobody had any coal to spare.
As a side note, there's a money-making scheme in here too: if you had any good ideas for Wolfenstein levels but couldn't or wouldn't make your own, Thomas would create them for you, $1-1.5 per floor. Or even for free if the idea is particularly good. It would be delightful to find out if anyone's ever tried to take up the offer; unfortunately I don't have such information, nor any other scenarios known to have been authored by Thomas Elgin, for that matter.
