I was going to comment on the SPACE GAMER article " Project File: Discovery" but Nuke11 beat me to it. Nicely done!
The reason I created the Frozen Watch teams way back in 1988 was because there was no quick way to get new Morrows into an existing team [replacing dead player characters, as well as introducing new MP player characters to an existing team].
The basic concept of the Frozen Watch teams is that they are minimally armed and equipped, waiting to climb into a dead man's shoes on an existing Morrow team. They normally sleep in a small, sparse, bare-bones bolt hole, which lacks even a periscope package. The idea was that a team in need of replacements could use their AutoNav and look for a map notation of "abandoned ash pit", which was the cover for the hidden replacement teams. In fact, Morrow Industries engineers would actually place a fake ash pit with waste slurry at the site to mark it.
Spotting & entering the FW bolt hole from outside is pretty much identical to that used to locate/recover a cache: a fake benchmark, stainless steel data plate listing the FW team's location, keep digging and wake them up.
Unfortunately somewhere in the editorial process for "PROJECT FILE: DISCOVERY" one crucial line got lost: how the team came to be awoken just at the moment the Badges are upstairs having "a party". The original shelter notes were that "entrance to the cache of MP emergency gear was a stainless steel panel set in the floor underneath the base of the ladder to the roof, built in such a way as to appear to be a metal floor pad. The unmarked card slot would be in the wall behind the ladder so as to be rather inconspicuous."
What is missing from the SG/FG mini-adventure is the line that one of the halfway-bright Badges found the card slot and "tinkered" with it (starting with a screwdriver, and ending with a crowbar). Somewhere along the way the 150-year-old electronics shorted out, and the bolt hole computer started the Emergency Revival Sequence for the team. Hence the reason the team wakes up at just the right moment to (maybe!) save the day.
To be honest, I am rather surprised to find anyone even remembers the original magazine article I wrote way back in the 80s!
The FW teams got little other notice save their mention in THE FINAL WATCH. It's pretty cool to see people picking up the idea and working it through.
Thanks!
