Mecha Level 4 Sentry

The Mecha Level 4 Sentry is an experimental boss from an old Mann vs. Machine prototype from 2009 simply called "Raid". In this "Raid" gamemode, players would be on a 5 man team and enemy bots would spawn in, much like in Left 4 Dead. Much like today's MvM, Raid would've also featured waves of hordes with unique enemies, but would've also had boss battles.
The existence of this boss was first discovered in the form of filename strings found in some
.lst files from before the May 13, 2013 Patch when all
.lst files in the
tf\reslists folder were deleted.
The filenames found are all for various sounds relating to a "robot boss". The names of the sound files give hints as to what abilities this boss would have had in combat.
As well, filename strings for a pre-MvM Soldier bot were found in the same reslists. Whether this was the same model as the one in MvM, or if it was a potentially earlier version, potentially using the early MvM bot heads found in the Source Filmmaker
tf_movies\models\props_facemovie\botheads directory is unknown. It is also unknown whether or not this bot was one of the general enemies one would have fought in the Raid mode, or if it was specifically for the Mecha Level 4 Sentry boss fight.
