Distance 24 Feb level 20 Command Center — Someone finished it?
I wonder whether someone was able to get the legendary fragments during the challenge by beating the 5 level 41 heavy armored walkers with about 140k health. One strategy could be using Sasha and 2 assaults in the corner and permanently stun the walkers while recharging in parallel. Unfortunately, I was unlucky to set up my team in time and the heavies are blocking the upper left corner. Now I lost Sasha and all my good assaults.
