Mechanical Engineer Update

Where's your cloak now?

— The Engineer to Spy

”

The Mechanical Engineer Update is an unofficial community-made update by Samuel Pires and inspired by Diamo Lima's Guard Dog Update. It was released several months prior to the official Engineer Update.

Day 1

Day 1 introduced a new building called the Mothership. It appeared as a small team-colored blimp that acts as a Dispenser. The idea of the Mothership was it was easier to move around when changing spots.
The Mothership's downside was the gas used to fly was Template:W, a flammable gas. If the Mothership was damaged it would explode and possibly injure both teammates and enemies.
A snapshot was featured of a new map called Generator.

The Hellraiser was to be released on Day 2. It was a Nail Gun with a mini-container filled with radioactive gas provided by Mann Co. It was intended to give away cloaked Spy positions with a green radioactive glow.
The nails are supposedly made by Saxton Hale's teeth.
The Achievement Idle map was designed to let players either play the game or Idle in the spawn room. It was designed to be a King of the Hill.

The EMP was a projectile that the Engineer could throw to destroy Sticky Bombs, Sappers and other electronics.

The Machinist Chest would allow Engineer's to reload weapons faster and attach all sorts of accessories to his buildings.
The bottom of Day 4 had a message from Samuel announcing that the update was indeed fake and explaining how he was inspired by Diogo Lima and his Guard Dog Update.
The engineer achievements were joked about, saying "Write every one? OK, I give up!" whereupon the previous message was delivered.

The Teleportal worked like a regular Teleporter, except it was capable of attaching to walls or ceilings. It was designed to be thrown rather than carried.

The Engineer wrote some notes next to the images of the Mothership on Day 1. He referred to it as "Engineering Project #25" and said he was getting tired of packing up and redeploying his buildings, although it wouldn't give as much metal or health compared to the stock Dispenser.
On Day 2, written on the Hellraiser's Page, the yellow colored letters in the sentence "This masterpiece is a Radioactive nail Gun!", spell out the word "Railgun".
Day 5 was titled "The Fake was a Lie" rather than the famous quote from Portal that has since developed into a meme. It also had "Enjoy The Cake Update" at the bottom.
- You can also see what seems to be staples next to the "F" in "THE FAKE IS A LIE" and the "C" in "ENJOY THE CAKE UPDATE"
