Found a unique little Hornet glitch that you may find interesting. (More of a glitch, but you can call it a trick I suppose.)

It all goes down in the campaign on the level “The Covenant” at rally point Alpha. The deal is; you destroy the two Hornets that are waiting for you and wait for the third to arrive. Somehow you’re supposed to board the third 3 Hornet before it touches the ground.

If you’re able to do it correctly, you’ll be able to fly almost anywhere according to this article. Apparently, the “invisible walls” don’t show up and you’ll be free as a bird.

Here’s where it gets interesting. According to this dude:

For starters you can backtrack up the picturesque canyon and explore the area around the first tower, landing on hills and stuff. You can likewise get onto hills along the landing beach. But that’s not all. By an indirect route - because the direct one is blocked by an invisible wall - you can also get to unusually high locations along the coastline to the third tower, giving you some novel attack opportunities. At the third tower itself, you can even use the Hornet to get yourself (minus Hornet) into the snow section beyond, not yet populated! There’s also plenty of weirdness to see along the way - graphics glitches and more.
