here's a easy way to beat this level
use shock wave, since the enemy mostly shield wall shock wave can both easier break the shield wall and unequipped their weapons, this have the downside of you breaking your team's shield wall
mini boss, the mini boss is easy since you can easier take him out by throwing your weapons at him or using your power which is free due to your team getting kills, the same can be said for the king boss

nice
