This may seem minor, but it does affect speedrunners. While flying the Hornet, some control schemes will not allow the player to lower altitude without using equipment. Because of this, it’s not possible to do the Double Scarab Board on The Covenant while keeping a Cloaking since lowering altitude is required, but doing so will expend the Camo, and this is currently the most popular speedrun strategy for this level.
I had no idea that you can use camo in the Hornet. I guess you will have to change to recon right before entering the hornet.
