FIELD NOTES: The original Hunchback was susceptible to rapid heat buildup, but after it was retrofitted with Star League heat dissipation technology, the problem was solved. Remarkably fast for a medium ’Mech, the Hunchback can also deliver massive damage at short range, making it ideal for urban combat.
