Will human players be able to see the energy links between units ?
Human players will be able to see the energy links between alien units only.
I think it could end up a bit confusing, too much blinking and lighting on the screen, making it difficult to see what the situation is.
It will not blink frequently, it's more like a slow energy flow. I think that's accentuate the difference between enemy and allies when looking from afar.
Thank you for your suggestion. This is one fresh idea from me:
A group of more than 10 linked units can create a one superunit. During this small units are destroyed, but give birth to one super-power unit.
