I don’t see it listing Microsoft Flight, I had it on steam for a while, and then it got removed…

I recently discovered Turbo Overkill, it has some brilliant arcade shooter feel, a great 80s style, and some unique quirks.

I highly enjoyed it.

My favorite FPS is however Unreal Tournament 2004, which I heard will be handed off from Epic Games to a fan community, so the fan community maintains it. I don’t know if that means it will be open source, but it sounds good.
