Hollywood Inferno is the seventh and final level of Alien World Order, and takes place in Hollywood. It is the most linear level in this episode, being literally just one route to the Hollywood sign where the final boss is located and battled.
- Trek up the path to where the fence ends and the rock formation is on either side of you. There is a cracked wall that you can destroy to reach this first secret.
- Face the tunnel that's blocked off by rock. There's a crack in the wall that can be destroyed that leads to the second secret.
- Inside the Employees Only section at the end of the tunnel, crouch down and flip the switch near the Shrinker. A hidden room right next to it will open up.
- The Hollywood sign can be seen in the background of most of the city levels in the earlier episodes. This is the first time the player finally gets to visit it.
- The "DUF BEER" blimp from Stadium returns above the Hollywood Sign. Destroy it with an explosive for goodies such as weapons and items to use.
