Here are two tool-assisted out-of-bounds entries. First using the standing pylons, then the geyser glitch (which also worked on the bounce pads in quarry).
I'll be posting one more video about Endfield for the technical test, but this one summarizes my thoughts on the game as it stands right now.
Remember, this is a TECHNICAL TEST. This is probably not going to be representative of the final version of the game.
Cheers!
