The only specialist missions that are required to beat the game are Brother in Need (Karoosh) and Trapped (Wogah). Blood of Oros is not required and neither is On the Hunt (Jayma).

I also found Big Darwa Fort and Fire Screamer Fort are not required. You can simply run through/ them to get to the final missions.

So I've found some small time saves on Visions of Beasts. At the beginning of Visions of Beasts and Visions of Ice (not Visions of Fire though) there is a small window that lets you start sprinting so when coming out of the loading screen spam click the sprint button and it will let you sprint.

If you veer off high and to the right you can land on land and skip the small swimming section.

I just pick up resources for their huts and weapons along the way, so i don't get them all at the beginning. I assumed it was faster but haven't timed it.

It takes longer to light your club and an arrow on fire, unless you can ignite your arrow first, which i haven't tried yet.

Another thing, if you skin the three wolves at the beginning and grab the wolf skin when you tame the white wolf, it saves you 4 skins so you only have to kill and skin 2.

The best route i could find for getting resources to build the bow.

After you light your club on fire you can throw it at the vines to burn them. Saves a small amount of time.

You can jump past the water in the cave. Another thing i found is you can dive into the water but land on the rocks to skip the stumbling animation. Haven't tested it much yet so i don't know if it's consistent.

If you shoot the bonfire from a distance with a fire arrow you can save a large amount of time and get teleported to the bonfire.

Have something that saves a small amount of time or could be useful to runs? Post it here.

I think Far Cry Primal has potential to be a great speed game and i'm glad to see others interested in running it.

About the rules, I think difficulty and aim assist should be the runners choice. I agree keeping PC and console separate since loading times can be pretty long on PS4. I think the timer should start after the loading screen on save creation and it should end when the final cut scene starts.

Also I've finished the game and routed up to Attack of the Udam so far.
