OK Sektor players: Here are the Combos and strategies I learned from Practice Mode and watching a ton of videos and posts around the internet.
Combos:
f4,4,EX TU, b2,f2
homing missile, jk, EX TU, b2, 1
u3,4,TP,f4,4,EX TP, b2,f2
homing missile or up missile, jp,1,2,b1,jk,f4,4,EX TU, b2,f2
b3,4, EX TP, b2,1
corner-1,2,b1,1,2,2,XRay
Punish combos- f4,4, TP EX, b2,1 or b2,TP EX, b2,1
Strategies:
-You can do a 2hit missile across the screen by doing an air missile, then right away do a straight missile. This keeps them at the end of the screen.
-His b1 is awesome to push opponents back, and also does great damage for a regular move.
-His dash blocks are very quick, and can be used to gain distance or just use a b1 to keep them back again.
-After combos, do an extra up missile, homing missile, or straight missile to keep them from doing a wakeup moves.
-Supposedly (don't know if it's true) Human Sektor has slower missiles but faster juggles.
