Free Abilities?

[dnzrx]

My second set of questions deal with free unit abilities.

Does this mean that units can have a "third ability" potentially?

And do I have to pay extra for such things (like will my units be more expensive initially due to the cost of the abillities?)

Yes, if they have a free ability, they can still have two more abilities (once they have Neural Grafting, the tech prerequisite that allows a second ability).

No, your units won't be more expensive initially.
