A lot of people were wondering how to add Ark Additions spawns to gen 2 so I thought I would make a guide on how to do that.

The ark wiki has details on how to do that right here, it is pretty simple to understand when you look at the examples listed.

The creature id's are listed in the pinned discussion so all you have to do is copy paste it in there, fill in the entry weight listed, and find the spawn location entry id.

Inorder to find the entry weight and spawn location entry id you have to go the Gen 2 spawn map and find the spawns of the dino that most closely matches the dino you want to add. For this examples I am using Acros and the Rex most closely resembles it so I chose the spawn locations that had mountains and copied the entry weight of the spawn and the spawn location id and I was good to go

For you lazy people out there I did a favor for you and I'll give you the acro one cause i'm nice.

Note, i have not tested this and It might underspawn or overspawn so use it at your own risk, the math is right and it should spawn at the same frequency as a rex therefore making the rex spawn half as often in the mountains where the acro spawns. Note, this will spawn the x-acro not the regular acro.
