A new trailer for No Man's Sky was released today, showing how the game deals with trading and economy. This is the third of the pillar trailers showcasing the gameplay elements of No Man's Sky prior to release.
The trailer shows elements and resources being gathered which can then be sold elsewhere in a system where resources from all over the galaxy come together.
The first two pillars, entitled Explore and Fight, have already been given trailers, leaving the fourth and last one, Survive, still to go.
