How do you make certain units unlockable with points? Thank you to anybody who can tell me.

I used the search and I couldn't find it.

Gee, you sure didn't try very hard:

I'm sure there are others, but those are just the ones that I could find really fast by searching for "unlock."

Oh, I searched unlockable + units + points.
I'm very sorry for this. Please forgive me.

Just remember that the search isn't magic and can't read your mind. Always start with a broad search (like "unlock," instead of three or four keywords at once) and narrow down as you need. Don't use larger or more complicated versions of words ("unlock" vs. "unlockable") and try to search more than once.
