you have to time this, and it takes some practice. you have to hit them with the up fp right when youre about to hit the ground. after that, you can easily regular jump and do lp, mp, lk, u.hp, repeat. The trick is to jump way before you even see them on the screen… your hp should land RIGHT before you hit the ground.
striders = call his bird, i believe its qcf hk, it has to be timed so that it hits RIGHT as the new character is popping in, pause, c.hp after you see them “open up”
cammy = she doesn’t have any useful guardbreak. but i guess you could do one like this. call any AAA (anti-air assist), like capcom, psyloche, cammy… wait for them to open up, s.hk, sj. 1-4 cannon drill xx killa bee
sent = too hard for you to do right now if u dont know IM’s… but you can do it the same way as cammys. AAA, then launch.
Doom = better off doin the same with the AAA.
psy = i think you can jump in with a hp, right before you hit the ground… then do her launcher, a c.hp.
hope this helped.
the only REAL useful guardbreaks in the game are probably… magnetos, cables, sentinels, and ironmans. maybe a couple others… but those take lots of practice…
