The procedure from SCP Containment Breach required the player turn the power off to his containment cell and then enabling Sound Transmission, which then allows the player to lure him into his cell by activating the femur breaker and allowing the sound of the bait subject to be transmitted to the facility. Instead of having the current method of rushing somebody into the teleporter to his containment cell and pressing a big red button, there could be a power switch and sound transmission switch near the button on one of the computers in the control room.
I've always considered the idea of adding a recontainment procedure that's more closely alligned with the method of recontaining him in SCP Containment Breach. He also has to handle the risk of swarms of MTF and CI getting to SCP 914 late into the game and searching for his containment room, which is sometimes impossible to defend if there are enough people shooting at him and forcing him to hold his position or deal with the possibility of multiple people getting around him and recontaining him. It seems a bit too easy to search for and rush into his containment room very early into the game if Class D's and Scientists manage to find it.
Having the ability to contain SCP 106 is really interesting & useful mechanic considering how strong he can be at times, but it's incredibly easy to do so at many stages in the game.
