The Orb first sees that it is actually normal reinforced glass, but there is a corridor exactly like they are in, on the other side. A simple trick it is, then it follows onwards. The Orb and the soldiers following ahead see what the red light is, as they come to the room, they see that it has a quite thick glass separating the place they are in, and some kind of munitions belt going upwards from the ground. There is a large control pannel to the left, a bolted plate to the right, and some weird rectangular slit on the other side of the room, separated by the glass.

Duelex, Beta and Delta come to a closed door in the end of the corridor, much like the one they busted through at the beggining of this part of the facility. To the left, a hallway about 1.5x the size the ones they just went through splits firstly into a left, then to a right, and then it ends in another door, much like the one they are besides right now.

The second Orb lands on the closest edge of the bridge, and it sees that the bridge's center has completely collapsed, glass shattered in entertaining patterns, metal bended like a huge weight came crashing down on it, and hid itself in the dark radioactive depths. The bridge seems to split into a left down where the center once was, and then runs again into the other edge of the canyon.
Behind the Orb there is an open door that leads to a corridor going left, and the same to the other side.
