Activating the Cheats Menu
Before you can activate any of Luxor 2's cheats, you will first have to unlock the cheat menu. This differs from other Luxor games where the cheats had to be activated by way of command-line parameters.
Begin the game as you normally would. After selecting your preferred profile, go to the options menu. Now, press the "Page Up" and "Page Down" keys simultaneously and release. Once you release the keys a window will appear that asks "Do you want to permanently enable cheats on this profile?" At this point you may select "Enable Cheats" or cancel if want to use the cheats for a different profile.
Once you select "Enable Cheats," a new button will appear in the options menu labeled "Cheats."
The Cheats
There are three cheat options from which to choose.
The first cheat option, "Unlock all levels," will unlock all levels within the stages that you have already unlocked, allowing you to play these levels in the order you prefer. The second cheat option, "Unlock all stages," will unlock all 13 stages of the game. Once you select a stage, however, you must play its levels in order. Both of these cheats can be enabled simultaneously, giving you access to all 13 stages and 88 levels of Luxor 2.
The final cheat option, "Unlock Challenge of Horus," should only be used by skilled players, as it unlocks the extremely difficult mode of the same name. Alternatively, this mode can be unlocked by beating the game on expert mode.
