Its hard to know exactly what to put here because the map is (was) so new... I do not wish to ruin it for those who want to try themselves so I will put secrets on here and the walkthrough underneath. Have fun with this cool new map either way.
Note: Most of this content is written by me however Time_Rift was the one who showed me around the level.
Secret 1 - A Chicken: There is a chicken is right near the end of part 1. It is just after you get the barrel from the top ledge (requires boost) and put that barrel in the fuel containment zone. Once in the green area get 1 person to boost you on top of the green plant to your left if you are looking at the path leading to the next part. At the top there is breakable ground and inside the ground there is a chicken. Video here (video required).
Secret 2 - Another chicken: Only accessable by noclip. This one is found ontop of the anti gravity room with the moving grates.
