Naughty Dog has revealed a wide range of details about multiplayer in Uncharted 4: A Thief's End, including some likely to cause controversy.

The multiplayer component of the anticipated sequel includes two new significant new gameplay features, in the form of sidekicks and supernatural powerups.

Sidekicks can be hired to fight alongside players, and "provide support by tracking your enemies, reviving fallen allies or unleashing heavy offensive firepower," Sony says.

Mystical artifacts, inspired by events in earlier Uncharted games, grant players extra abilities.

Sony says the artifacts include "El Dorado's cursed sarcophagus, Shambala's powerful Chintamani Stone or the lost city of Ubar's fiery Djinn."

On the technical side, Uncharted 4 multiplayer will not run on dedicated servers, but like its predecessors, operate on a peer-to-peer basis.

It will run at 60fps in 900p resolution, while the single-player component runs at 30fps in 1080p.

Microtransactions will also be present from launch, but the game will have "no gameplay items that will be gated through microtransactions," according to lead multiplayer designer Robert Cogburn.

Uncharted 4: A Thief's End launches March 18, 2016 on PS4; buyers of Uncharted: The Nathan Drake Collection can try a multiplayer beta from December 4-13.
