Also, during the center of the trip to the top, there is a walkway on the left and right sides of the walkway that lead to towers that overlook the Upper Lava Room.
At the top of the Minigun side is a perch overlooking the Upper Lava Pit with a XM-214-A Minigun with several Bullet pickups near it. Just before the perch are two large holes just past the elevators. On the left hole is a Super Health on a pole, while the right hole has a Large Health on a pole. These items can only be accessed by jumping down.

Upper Rocket Launcher Area
The elevator in the Red Room leads to the Upper Rocket Launcher Area. Just past the elevator is a Rocket Launcher, and past it is an entrance to a castle-like building overlooking the Upper Lava Room. On it are some Rocket pickups, and a bridge in the center of it. Underneath the bridge is a SBC Cannon and to the sides of the Upper Rocket Launcher Area, between the actual area and the Upper Lava Room Rim, are Cannonballs. The Cannon itself can be reached by jumping on wooden planks near the Cannonballs to the Cannon.
The bridge can be lowered by shooting it. After it goes down, there will be another bridge that points upwards that leads another castle-like area. Shoot it as well to lower it.
Upper Grenade Launcher Area
The bridges lead to the Upper Grenade Launcher Area from the Upper Rocket Launcher Area. Just past the bridges is an Invisibility item. To the left and right of it are paths that lead to the outside part of the Upper Grenade Launcher Area. These paths lead to the top of the castle-like area, which has a Grenade Launcher and several Grenade pickups.
Serious Sam HD differences
The Serious Sam HD version of the level has some minor differences. First, the Red Room is no longer red. Second, the Revolver in front of the right elevator in the Minigun Area is gone because the player spawns with a dual revolvers every time they respawn.
