Can anyone beat this?

I thought it was fun - played it a good while, had to retreat many times and died initially. Appreciate the challenge and I think it's fine for "bonus" content that people really don't have to complete. This isn't a paywall event where you're blocked from getting CLS or GK or something. You get a few zetas / omegas as a reward, which was cool and I appreciate, but in the grand scheme it's nothing to get super bent up about if you're not able to pass it.
