Sounds good.
But not limited to just...locations. Maybe technology as well can be kinda vague. Just 'Sci-fi'. That way you can mess around and have some creative stuff.
Like, one guy might be over there with like, a light-saber-katana thingy, while the other guy has cybernetic modifications drastically increasing strength and reaction time, while at the same time, making them weigh a ton (and thus, be rather painted when they fall in water or something..).
etc.
