Basement Flooring Underlayment

I'm helping my son put a play room in his basement (about 330sf). He'd like to use laminate flooring. The flooring would go in top of a concrete floor.

The house is 40 years old and there is some generalized spalling across the surface of the concrete floor. The floor was painted some time ago but much of it has peeled along with the spalling. In general, the depth of spalling is around 1/8".

The question is: what sort of underlayment should we use? Would cushioned (rolled out) sheeting work? How thick would it have to be? Or does the whole floor need to be leveled with epoxy floor leveler? Also, Home Depot has some flooring panels, though they're a bit pricey. A photo is attached.

Every flooring material has recommended flatness, (not levelness) you will need to check your floor using a long level and patch areas that are low.

And depending on the manufacturers recommendation underlayment's may or may not be required. If they are I have used this product from HD and was happy with it.
