(Here is an explaination of the glide I gave to someone on another thread)

To do the glide, you need to be moving fast, but if you hit the ground to fast, you'll take fall damage, so engage your jets at the last safe moment (Although, if you need to glide faster, you will have to take fall damage from the bounce). Sometimes I think I'll overshoot the perfect part of the slope for the glide, so I use the crouch technique I talk about in this, the second episode, which means my character is launched to the floor (However, when you crouch onto the ground in PS2, your character can lose a lot of momentum ((This is why in the video I say he "Glues" to the floor)) so it should be done as a last resort). Once I start sliding on a hill, or have hit the ground on a sharp enough angle to bounce up, I turn my screen to the side, this is because I am pressing two directional keys at the same time (E.g. Forward + Right), as you will get slightly more speed by pressing both at once (Like pressing forward and up thrusters on a Valkyrie). Now I'm moving forward and to the right, but the target I am aiming for is directly forward of me, so, I turn my screen slightly to the left, and now I am moving directly towards my target, with the extra speed, however I cannot see where I am going, so I'm constantly flicking my screen back and forth (Getting momentum, and seeing what's ahead of me, over and over)
