Previous versions of Command & Conquer™ had the ability to disable super weapons, but in Red alert 3 this option is abscent. After much googling for a solution, I spent some time creating my own mod that simply disabled the superweapons.
I like to play turtle vs. the Ai in skirmish, and develop intuitive ways to crush my opponent without having to battle vs. super weapons every 5 minutes.
Created based on SDKv3 and RA3v1.12, it disables the ability to build the weapons for both player and AI.
I created two different mods that disable one or both types of superweapons.
Update: Works in Uprising according to this comment.
