--- I spent about an hour trying to find last pieces of content
There is a changelog at the main menu that often tells you where something is if it doesnt have an in game hint. If its not there, then hovering over the missing memory or poster will tell you a hint to where it is.
--- I am not able to get into bottom left of the map and bottom right of the map
Games not done yet.
--- Dont have raptor spawn memory either
Go to Gapers, go south to past the area doors, very bottom wall has a cave entrance.
--- Vendi
I don't know what a vendi is. Nothing in game is called Vendi.
--- Also i failed 80%,80%,65% and after buying two 99% capture items i failed 99% and 99% on weakened Vendi.
Bad RNG. It will happen. Very sure the item also says something along the lines of "99% on nude/weakened monster". Nude capture is the highest chance.
