Bethesda has released a new video providing an in-depth look at Fallout 4's character development system.

The video, which is narrated by executive producer Todd Howard, goes through the various S.P.E.C.I.A.L. attributes and also the Perks. We're also given a look at the rather impressive Perk tree, which you can see in full below.

The chart is organised by the seven S.P.E.C.I.A.L. options and, according to Howard, "there is a Perk for each S.P.E.C.I.A.L. and each rank from one to ten."

"If you have the value, you can choose it. So if you come out of the Vault with ten charisma, you can pick the intimidation perk that let's you manipulate and control other people."

A total of 70 base perks will be available in Fallout 4, each with multiple ranks that alter the functionality of the perk. Bethesda goes into depth about the character upgrading mechanics on its official website.

Bethesda has announced post-launch plans for Fallout 4, which includes regular free updates, paid DLC, mods, and more. Fallout 4 will be getting expansion packs starting in 2016, the DLC content will be available through the game's $30 DLC pass.

Todd Howard previously said the game's mod tools will be available in "early 2016," but a more specific date could not be provided as the timetable was still "fuzzy."

At E3 in June, Bethesda revealed that Fallout 4's mods would ship on Xbox One before PlayStation 4, as part of a wider deal arranged with Microsoft.
