Legacy SCP-079


SCP-079 had been removed prior to Megapatch 1 and interacted with things by hacking them. Hacking time would vary depending on what was hacked, with some things taking up to 30 seconds. After hacking a door or tesla gate, SCP-079 would open up a menu that gives him options to interact with was hacked. SCP-079 would then use the number keys to interact with it. Pressing 1 would close and open doors. Pressing 2 would lock the door, but only if SCP-079's special ability was available. SCP-079 would use the WASD to turn the cameras. Using the mouse scroll wheel he could zoom. This version of SCP-079 had no map. This version of SCP-079 had no generators or AP, but could instead be killed by being shot.

In the alpha versions of SCP SL, SCP-079 could only interact with cameras. He also had a map of HCZ on his screen. He could change cameras by click on dots on the map. This was the only way to change cameras. He could also only look around HCZ. SCP-079 would use WASD to turn the cameras.
