Yup... I suck at it, but it's free.
I didn't grow up with this like every other person I played with last night (gooch, my youngest son, and a bunch of guys I've never talked to before who were enjoying martinis while they played), so it was just another FPS for me and not a journey through nostalgia (which is always better than how things really were). I did, however, have my moment, taking out a slew of combatants in short order. This was, of course, preceded and followed by a lot of suck.
Still... if a FPS where you play control or CTF is your thing, download it today and give it a whirl.
