Notes
Projectile: 
Rocket Punch Hyper Sentinel Force
Rocket Punch This is primarily used for rushdown play and as a combo-starter for many air combos, including some infinites. Recommended for rushdown and high-pressure play UP CLOSE. Don't send this assist out randomly, as it will leave Sent open for massive combos.
Launcher: 
Hyper Sentinel Force
Launcher. This is a nearly useless assist when faced with his ground and projectile assists. Just don't use it.
Ground: Sentinel Force Hyper Sentinel Force
Sentinel Force This is a great assist for pressuring and chipping enemy characters. Being a 3-hit assist, it will also neutralize many opposing assists if used earlier. Also something to note, since the drones hit some time apart and keep your enemy stunned for a moment, it creates a great opportunity to rush in and start a combo, also giving you time to decide what to do, since it gives you such a larger window than his projectile assist. Use it if you plan to keep-away, chip, or trap enemies. Widely used in crossups and traps.
