SCP 049 does need more freedom around the facility as well as significance. I think the tunnels he spawns at should be taken as a beginning of a new stage in the game: a more difficult stage where 049 is roaming around the site doing his work, adding to the hazards of the game.
As much as I agree with that, I also believe there should be a real purpose for entering his chamber, and I have a possible suggestion...
The elevator that allows you to exit should have a broken button which cannot be used. In order to operate the elevator, you must enter a small closet of electrics and manually operate the lift. The door to the closet should require a key which may be used elsewhere in the game, and the only key should be within the chamber of SCP 049. In consequence, you may only be able to proceed by entering the chamber and collecting that key.
ey b0ss, can I habe de pussi plz?
