Merge Weapon Run is a satisfying merge runner that turns into a tactical tower defense battle at the finish line. Run forward and collect numbered weapons like 2, 4, 6, 8… then merge them 2048-style: two matching weapons combine into a stronger one (2+2=4, 4+4=8, and so on). Build the biggest, strongest weapon chain you can before reaching the end.
