Sally is slower than Sonic and can't use spin attacks; however, she has a number of stealth and agility-based abilities to compensate and access areas Sonic had difficulty reaching, as well as the use of handheld device NICOLE:
NICOLE Laser Attack: Press and Sally uses NICOLE to fire a small projectile which hits nearby enemies and obstacles.
NICOLE Scan Mode: Press and NICOLE will send a data wave to reprogram monitors and other Eggman traps.
NICOLE Downward Laser: Press + / while airborne to fire at objects straight below. Sally also gets a small vertical boost.
Slide: Press while running to slide on the ground for a short distance. Sally can also slide under certain obstacles using this method.
Somersault Dash: Press + / while on the ground and Sally will somersault forward at a high speed. This is useful for jumping long distances.
