coneconeconecone
coneconeconecone_v1

A maze with the same layout as mazemazemazemaze, but a different spawn point. The walls and floor are transparent, and there is a water texture beneath the floor. The original spawn point now contains a giant cone. The cone is named "cge7-193", shooting it shows it taking damage and upon death it screams.
In Hammer, the cone has multiple sounds, named "they_programmed_me_to_die", which is the zombie scream, "myvoice", which is canals/windchime5.wav, and "hurts", which is warningbell1.
When debating on sparing or killing the cone, the server changed to "pleasekill".bsp which wasn't on the server at the time.
Contains what seems to be the "intelligence" of Entities/CGE7-193. Upon killing the cone, the server shut down for an extended period, and Anomidae's Xemu HL2 was "unlocked".
Discovered by completing mazemazemazemaze.
coneconeconecone_v2

The same as coneconeconecone, but there is no cone and the spawnpoint is where the cone used to be. There is now a trigger and a torus on the side of the map for "cone.cfg".
Anomidae's TF2 was on this map and his screen is completely blank. This map led Anomidae to subroutine_hello.
After Tadzy killed the cone, the server shut down and changed to this map.
