Tips worth considering:

#1: Bring a friend or play spitscreen.

#2: ALWAYS use bio token, not narcotics. They work, but you'll be there for literal hours.

#3: Use any gun other than the long neck. An upgraded simple pistol will work.

#4: Bring a very tanky tame that you can shoot of the back of. Examples like the thyla.

And #5: When you finally get it down, make sure to have metal spikes on you. I lost a max level to a carno because I didn't have spickes. The metal spikes are worth the investment of materials.

I hope this is helpful to some of yall out there!
