Hi there!
I'm looking for this game I was playing in the early 2000s in my first PC. It's possibly older and I'm 80% sure I saw it on the Android play store once a few years ago. It's a top down twin stick style shooter set (possibly) on earth. You fight these aliens with elongated heads(kinda like in Aliens) but they have weapons and some other bulky enemies. You collect weapons and pick ups, and you have a limited number of lives, which wheb you run out, you need to restart the campaign. It includes boss fights with a tank, a flying gunship and a walker. I also remember the 2nd or 3rd map ending with entering a underground train or something. The name of it might be something like Extinction or the such and I also remember the icon vividli, which is an X with a dot above it mimicing a person.
Please help, I'm dying for some.nostalgia.
