Warner Bros' Injustice: Gods Among Us Ultimate Edition has joined Sony's next-gen trade-up scheme.
Eurogamer reports that those who buy the PS3 version of the game will in the box find a code that, come the game's PS4 release, will entitle them to buy the next-gen digital version for a discounted price.
If you buy the digital version of the game on PS3 then a discount will be automatically applied to the digital PS4 version.
Note that the offer does not apply for those who already own the standard Injustice: Gods Among Us.
Other games that offer a similar discounted trade-up include Battlefield 4, Call of Duty: Ghosts, FIFA 14, Assassin's Creed 4: Black Flag and NBA 2K14.
