So I play this with my brother a lot, and he uses the Cybran all the time because of their stealth. So, I'm not sure if this is possible, but I think it would be nice to have alerts play when an enemy unit enters radar range, and a secondary alert if omni picks up an enemy unit.
The thing is, I don't like having to constantly recheck my perimeter, since I want to focus on my base, especially early in the game, so I think this would be a nice feature.
(Apologies if such a post already exists, I searched for such, but found none. )
