50 Easter eggs from offical and custom maps for PAP Mystery Box
Hi I need to know about easter eggs as I want to get to 50 EE for PAP Mystery Box so I have some questions.

1. Do buyable endings count as easter eggs?

2. Do side easter eggs count as easter eggs?

3. Is it only main easter eggs count as easter eggs?

4. Which offical maps and custom maps have easter eggs that count toward the easter eggs counter and how many easter eggs from each map?

Please as it is very frustating for I really do want to get 50 EEs.
