Grind Survivors - final Infinity Level Help

Hi all,

Just wondering if anyone has managed to get to 40 minutes or more on the hardest Infinity mode (third bio) on Grind Survivors? If so, do you have any tips/builds etc that i may not be aware of as I can't seem to get past the 20-25 minute mark whatever I do.

I have researched about half a dozen builds/weapons etc but none seem to do what I need despite being very careful with synergies etc.

Playing on PS5 and if anyone can help to save my sanity it would be appreciated.
