Good job in beating this map. =)
I consider this one of the toughest, since the boss demands lots of player skills.

We built something similar, but had the wrong set of towers at first. Today we at last beat this map with 5 FoS using this maze. Characters: Sweet (Core Guardian and both Long Distance perks, REX + Battle Rifle), Skye (tactical juxtaposition, resilent core, shocking revelation, Drone Launcher + Plasma Rifle). Towers: Anti-Air, Lightning, Slow Field Dispenser, AR-Mine Dispenser and Range Spire. Killzone was around this U-like corridor above T-like block set with range spire in the center.
Thanks for guide!

Works like charm!

Beautiful.
