Players are independent citizens of a police state governed by people who collaborate with an extraterrestrial race that, to their knowledge, has conquered the planet.

System: d20 Modern or M&M 2e Agents of Freedom
Background:  Must be suitable suburbian inhabitants.

This should be from the perspective of resistance fighters.

This seems like it could be a lot of fun. Color me interested. Personally, I'd prefer d20 Modern, but I'm familiar with both systems well enough.

This sounds very much like XCOM 2, in which case I could be interested. However, the latter system is a completely unknown one to me. The d20 modern is available for free online, isn't it?

I've posted about looking for a game like this with superheroes. I've got a concept but he has powers.

@mediiic M&M = Mutants and Masterminds; 2e = 2nd edition; Agents of Freedom is a supplement.  Very flexible game system - I prefer it to GURPS.

While I would root long and hard for d20 MnM makes sense espescially with the ability to give us futuristic weapons
