You drop into Sin Mark and immediately start tracking down marks, dodging hazards, and racing to clear each stage before the pressure stacks up. Move through tight corridors and open zones, line up your hits, and chain clean runs to push your score higher with every level. The controls stay simple so you can focus on reading the map and reacting fast, while each new area throws fresh obstacles and tougher patterns your way. It rewards quick thinking and steady hands, and the runs are short enough that "one more try" turns into ten. Ready to leave your mark?

Tips & Tricks
- Clear the easy targets first to build momentum before the scren gets crowded.
