Completely my words. But if it would just do something silly like shooting rainbows... Well, that would be for a great trolling video
Ooh, like the extra piece of technology you can find on some or all maps in Krush Kill 'n Destroy (KKnD). You could find an extra strong robot in that "box" that you could take control over. Well, I think it's in KKnD ......
Mystery Box should only be captureable by commander. And there definitely should be a hughe questionmark above his head.
Would that be the Tesla shooting Tank eating swirly thing of death? It's a Chrono Vortex I think. I haven't used the RA rules editor in some time. You could create one from overuse of the chronosphere but I seem to recall it appeared in the crate options too.
Your thinking of the Survivors Campaign where they find the buried technology that makes that particular level easy... Fun times Used to play that game solid back when I was about 10 or 11 lol
Mysterybox should have a chance to become a super magnetic cube. Anything that goes near it gets sucked toward it and attached.. and it starts rolling around.. as it rolls, it collects more and more rocks, trees, units.. until it becomes huge, develops rocket engines, and blasts off into space, trailing asteroids and planetary debris...
