The Core is a total conversion single-player mod for Half-Life. Survive the disaster as Maurice Andrews, a low level engineer stationed in Black Mesa during the events of the resonance cascade. Seemingly trapped, Andrews must fight his way to the surface to survive.
Since the start of the mods development, this room in the first level is where the player meets Dr. Morris. After briefly explaining the situation to the Maurice (player), he then provides the gear to get started and sends him into the lower areas of the complex to meet up with other surviving team members.
The room has been redesigned 4 times overall.
2007 - First version of room was originally added to the mod. It's only purpose was a briefing room for the player to get their objectives and gear and head off into the labs. In contained a storage area for the HEV suit and crowbar and was listed as a "control room" by the exterior signs. This room can be seen among some of the first media released on MODDB
2008 - Using the submerged.wad, the room was radically redesigned for a more futuristic look. Despite being much happier with the result, it didn't really suit the Black Mesa theme of the mod. The storage area and "Control Room" sign remained untouched.
2012 - Owing to the submerged.wad being phased out, the room was gutted and re-purposed as a security booth which remained faithful to the rundown appearance seen throughout the opening chapter. The area remained fairly bland for over a year and the intro sequence and dialogue were removed to be rewritten.
2013 - July, the security office was totally removed, leaving none of the original 2008 brushwork in place. The area was redesigned to be Dr.Morris' laboratory, where the security officer helmet (essentially equivalent to the HEV) was designed and developed. This extends the first map somewhat and the player will need to do a little more work in order to acquire their gear before the mod can begin proper.
