First OOB was found by SpidyBawlz, the last was found by a someone I don't know, the rest were found by me.
Right in the first room of the mission, there's a forklift under where you're standing. You can squeeze between it and the wall, then with some Tobey 3 magic, you can clip through the wall into the outer side of Mechabiocon. Tobey keeps quipping throughout the whole exploration, because I wasn't spotted by the guards.
Some platforms are higher than what the texures look like. In some places, you can web zip, but can't swing, even though it looks like you should be able to.
I feel like I missed some parts while I went through some other part a few times. Maybe, I don't know, the whole place looks the same to me.
5:05 - This is where the mission ends. As expected, the trigger to finish the mission is not loaded this early into the mission.
6:20 - This is the place Spidey goes to after talking Dr. Andrews.
10:15 - Going back in bounds. Since I was too far from this part when exploring Mechabiocon, The map has deloaded. It takes a while, but the map is finally loaded again. However, the room where you need to go to is blocked by a door (11:00). It seems like this area is loaded by default with the door closed, and only when you first load it in the mission, it loads with the door open.
I could not find a way to clip through the door.
11:45 - In the room where you talk to Dr. Andrews, the room has pretty weak walls. Grab the wall at 11:50, drop down with a little jump (do not move around), charge-jump and hold the grab button. If done correctly, Spidey will face the opposite side of the wall. No you just need to do another charge jump to clip out of bounds.
From here, I explore the place, backtrack to the beginning and go further into the mission. The map is filled with softlock spots, invisible walls and non-solid textures.
Not all parts of the map are loaded and those that are, have the enemies and switches not loaded. Suffice to say, the trigger to end the mission is still not loaded.
17:15 - You can enter inside the room with the robot arms from the air vent that's only partially loaded. This is the "enemies and switches not loaded" part that I meant earlier.
24:00 - Clippin back to the room where you talk to Dr. Andrews to continue the mission. You can either clip back inside or find the trigger to the cutscene while still OOB.
24:30 - The first switch you press closes the door to the entrance of the room. It also deloads previous parts of the mission.
24:40 - I use said door to clip OOB. The cool thing is, some parts of "Mechabiocon Exposed" (Scorpion 3 mission) are loaded, because both missions share the same room.
25:00 - I go to the Scorpion 3 area and get back in bounds at 6:20 through an opening in the floor. In the other mission, beneath that floor is another room filled with deadly lasers.
27:20 - No lasers in the air vent like in the mission.
27:45 - This is the shared room in both missions. In this mission, you get here from the room with the giant robot by the air vent. In the other mission, this is where you fight Rhino alongside Scorpion.
28:35 - I backtrack to the robot room from the air vent to coninue the mission.
29:15 - After the QTE, instead of going through the air vent, I clip again the same way as I did before. Finally, the trigger to end the mission is loaded and I finish it at 31:00, skipping the expected route.
I didn't time this route, but I'm pretty sure this is slower than the normal route, even if you have to wait before finishing the mission.
BUT WAIT! THERE'S MORE!
If you take the normal route, there's another clip.
32:35 - This spot in the wall is not solid, or at least it's a very weak wall. All it takes to clip through is running against the wall, that's it. Then web zip to the right to clip out of the building and find the trigger to end the mission.
However, you're still restrained by the mission's timer. You risk being too slow and too fast to complete the mission. This route is for swag purposes only.
This was found by a runner that has removed his run. I don't remember his name unfortunately.
