UPDATE: No Man's Sky developer Hello Games is being investigated by the Advertising Standards Authority.

The ASA is investigating false advertising claims that have been made against the No Man's Sky Steam Store page.

Fans have argued that certain screenshots aren't representative of the final release, both graphically and in terms of features promised.

ORIGINAL: No Man's Sky has been given a huge PS4 price cut on Amazon's UK website.

UK customers can pick up a copy of No Man's Sky on PS4 for just £24.85, which is down from its pre-release asking price of £46.

The offer appears to be limited to the UK, because the North American store is still selling the game for more than $50.

Prices don't appear to have been cut elsewhere, with GAME, the PlayStation Store and Steam all still selling No Man's Sky at full price.

It's possible No Man's Sky will be discounted on Valve's platform soon, however, because concurrent Steam users have dropped to an all-time low.

No Man's Sky started strongly on Steam, attracting more than 200,000 players-per-hour at launch, compared to less than 1,000 at the time of writing.
