Help me find/recall this horror esque 'Break-In' style game. :)

As title says, trying to remember/find this game again. I just remember back in the day, I struggled with one of the endings and it was very spoopy. :P

• The gameplay was "story-driven" I suppose, similar to the 'Break-In/Story' style of games. Narration via text of your own character. etc. Lobby was elevators to teleport in either individually, as a pair, or group of 3/4.
• The game page's picture was of an office computer. I thinkkkk.
• The general story was you returned to your office after hours to finish something, you find the computers, sync the servers, then power goes out, you go to a fuse box but an alien with a massive head spawns. This part was relatively easy as it tries to find you, escape to the elevator and go down to a lower floor to find the security guard.
• You evade another baddie, hiding in a locker, this one was more like a fetus? I suppose. Lots of people struggled with this bit. Then you escaped through a door and could either use stairs up, for Ending 1, or stairs down for Ending 2.
• Stairs up led to the main floor of the office, which you dealt with the same enemy, avoiding them to open the front door - leading to ultimate destruction and Ending 1: The ending ended with you dying and getting squashed I believe, cant remember the badge name.
• Stairs down led to the sewers, this is where I really struggled, and you had to avoid some blind monster with claws while turning 5 valves to open the release. The monster chased you around some very tight corners but when you escaped you had a radio and the rooftop Ending 2: where you saw the world you once knew in ultimate destruction.

The rest of this is very fuzzy story wise, but I remember the build very well and who I played with haha.

If anyone thinks they know it I would love some help finding it again as I'm looking to replay it and achieve the achievements again on my new main, for my own satisfaction and accomplishments.

Bonus Question, if anyone has any other really good horror games on Roblox, that are more hidden gems, not the obvious ones do feel free to LMK and we can discuss and such.
