I've got a Lv. 9 ViperBot and a Lv. 11 ClawBot that has 17,138 and 29,985 Shields respectively. Is this normal? That seems ridiculously overpowered, and they keep getting stronger! Even at 10% of those shields, they would still be a challenge. Right now, no matter what tactic I use, they just seem to be insurmountable. The last Assassination mission I tried had two ViperBots and a ClawBot. It felt like I was fighting Lavos on my first playthrough!
Am I doing something wrong?
