I asked for tips and got flat ignored ��
I can't point you a video, but can share some tips that helped me early on:
Don't throw punches randomly! Whenever you throw both punches, you're rendering yourself defenseless. Always make sure it's safe to throw the second punch or you'll be an easy target for a grab or worse.
Be aware that your ARMS can be curved when thrown. This is useful not only to give a little chase, but also to get around defenses like shields or heavy ARMS or catch someone when they try to dodge.
Remember, the longer you charge after dodging, the more time you'll have to make use of the ARMS' additional effects. Of course, you have to be aware that charging will also leave you vulnerable.
ARMS have different weights. Usually fast ARMS are light and slow ones are heavy, with the average ones weighting in at medium. Two ARMS of the same weight will knock each other down. A heavier ARM will always knock down lighter ones and continue on it's merry one toward the target. Say you use a Retorcher (light) and I throw a Megawatt (heavy). The Megawatt will knock down your retorcher projectiles and continue toward you. Be aware that, during Rush, all your ARMS weight category goes up by one! So a Toaster (medium) during Rush can knock down other medium ARMS and continue it's trajectory and stop (and be knocked down by) a heavy one, like a Megawatt.
and above all:
Try lots of ARMS! There's a lot of variety in how they work. Some are blinding fast, some are slow and steady, some can curve in all 4 directions...
My personal favourites:
Slapmanders
Great to catch dodgy foes. Aim at where they'll be!
Hammers
Heavy ARMS with an unusual movement. Awful to defense from grabs, but they do good damage and strike from above.
Birds
Can strike from all 4 directions. Great against jumpy foes (strike em from below!) and dodgy ones as well. Can easily curve around heavier ARMS. Have a short range, though.
Blorb
It's just fun! Awful to block hits, but the bouncing way it moves makes it somewhat unpredictable. If you're high up, it will always fall straight down, so it's mostly useless against foes that jump a lot. If anyone has tips to share, I welcome them =p
Funchuks!
Fast ARMS. If throwing while in the air (including jumping sideways while defending!) it will spin facing the opponent rather than the usual side spin, covering a wider area and protecting you from smaller ARMS.
Hope this helps =)
Oh, right! Regarding SPRINGTRON!
I can confirm you CAN'T lose a single fight to face him. You have to win 2-0 all the way.
