How to S-Rank "Ambush the Vespers" Armored Core VI

I personally always take out the quad legged AC first, it does more damage and your helper can keep the quicker weaker one busy. As usual, staying above the ac while strafing around it and raining songbirds/stun needles from above is helpful until its time to close in with assault boost for big damage on the stagger. After the Quad is dead, the quicker one is pretty easy to take out. -- Watch live at https://www.twitch.tv/nemodex
