Those chicks are assassins. Dodging them is insane in the restricted space, shooting them down before they reach you is nigh impossible in the bubbles, and not triggering them is also really hard with all the interleaving.
Today’s hard daily had three epic waves. The bubbled assassins messed me up and I lost 3 lives, then the UFO roulette got me and while I only lost one life in that, I still had a hard time, then came the Play Both Sides Wave and on the last ‘phase’ the portal spawned in toxic chickens and ARMORED EGGSHIPS, and on top of that, I went to the side with the eggships. Needless to say, I lost a life there as well. So yeah, today’s hard daily was kinda brutal…
