Thanks for responding.
No, the location doesn't matter. Basically, in the scenario, there's two kaiju-esque beasts fighting. The PCs have to get from point A to point B. The goal for the PCs is to navigate the battle zone to get to their destination. The more I think about this, it's kinda like a chase sequence. I've never run a chase sequence in Starfinder, but I played a chase sequence in Pathfinder. Basically, as the PCs move from point A to point B, obstacles will get in their way and they'll have to make choices and checks. For example one of the beasts gets pierced and blood splatters on the ground, you have to navigate across the blood...acrobatics checks, oh no! you fell, blood is toxic! Roll a save...etc.
So I'm looking for a scenario like this that already exists. Not the plot or story elements, but rather the mechanics. Obviously, there's no exact match. But if there's a scenario where PCs have to move across some type of obstacle course, with urgency, I can probably tweak the mechanics and make it work without have to write the whole thing on my own.
