So, the main purpose is on how to upgrade your heroes correctly, in doomsday last survivors. I see many people making this mistake while upgrading heroes. Although I have 2 or 3 videos posted on the same subject, but it was well before, I had around 300 subs at that time, I think.

So, just to revisit the subject and to once again, put if out there for new and young players, I have mentioned this legendary hero upgrade guide.

Good luck on your upgrades and what was your points tally for the day?
