Pulling to a halt after the first gunshots, Seth immediately turned the bike around and pushed it around the corner of the bend in the path, away from the trap. Spinning around after gaining some distance, he pulls down his goggles and proceeds to mentally inspect the situation. In his mind's eye, he could see red lines marking the pathway itself, potential routes up the wall, the positions of his allies, and likely positions of the enemy. They had cover, but were camped in a position on top of a canyon ridge that was not likely to be easy to scale down. Running directly through the canyon was dangerous and likely to lead to injury, unless...
Seth proceeded to rifle into his saddle bags for some components, pulling a vial of powdered chemicals used in oxidizing metals, some powdered coal for fuel, and some simple black dye. He didn't have a moderate to keep the reaction from getting hot, but he only needed it to work for a little while. Pulling a glass bottle from the bag, placing it between the handlebars securely and pouring the materials he had pulled into the bottle along with a lit match, he waited a few moments, and soon the reaction had begun. Black smoke began to pour out of the bottle, thick and opaque. Pulling the collar of his outfit over his mouth and leaning down so he could see under the smoke, Seth pulled the bike around the corner and gunned it for the exit, trailing a smoke screen around his bike that should at the very least make him hard to spot. If he made it out, he could start looking for easier access to the top of the hill, but he wouldn't be abandoning his bike to be potentially stolen by more bandits lying in wait.
