an Arma that kills RCs and OMs (for more diversity)

[God, maker of the world]

Armageddon is a nice way to spice up a game, and so I just thought it might be a good idea to have another thing like Armageddon, and I don't know what to call it but:

This 2nd Arma-thing should only kill all RCs and Overminds.

This would force people to stop camping because bases have no power. Ok, there's the crates/containers and mines etc., but I think it's worth a try as some more spice for the game.

EDIT:

I just realized the explosive power of the RC would make this gimmick into an advantage for aliens. Maybe. :/

If the explosive effect could be suppressed by just removing the RCs and OMs (without exploding them), it would be better.
