FinalAlert

Final Alert 2 is the most popular Map editor for Red Alert 2 and Yuri's Revenge. The Tiberian Sun equivalent is Final Sun.

Description
Final Alert 2 allows one to create both single player missions and multiplayer maps. Other than being a Map editor it is also a Triggers editor, allowing a mapper to create his own scripts to make a level more unique, such as adding light effects, ambient sounds or, in single player missions, in-game "cinematics", messages, effects and so on.

Final Alert 2 supports mods and Mission disks (An option allows one to disable them, however.). It however doesn't allow one to create maps bigger than 200x200, although maps bigger than 200x200 exist on the internet.

Easter Eggs
There is a hidden minigame in the Map Editor.

Versions
There are two versions of Final Alert 2: Version 1.01 and 1.02. Additionally, Final Alert 2 was released for Red Alert 2 and later for Yuri's Revenge, so some versions of the game do not support Yuri's Revenge.
