The long arm of the law is only as long as it can run. This is where the Vaulteur AMBULATE upgrade comes in. Initially only used on the Vaulteur Hunter-Killer droids, the SENTINELS realized the potential of the AMBULATE was universal, and began offering it as a free upgrade to their personnel upon promotions or worthy citations.
A streamlined combination of flesh and circuitry, muscles and servos, bone and wiring, the AMBULATE upgrade allows the SENTINELS to run faster, jump higher, survive falls from heights of 100 ft or less, heal leg and foot injuries, and even run along walls if modified with experimental antigravity emitters.
The AMBULATE upgrade gives the SENTINELS the extra edge they need to keep the cities safe and secure.
