Portal 2 was released on pc, ps3 and Xbox 360 in 2011. It is one of the best games of all time and frankly, Valve should work on a remaster to improve its visuals on PC and bring the game to ps4 and ps5. Xbox One players were able to play it due to backwords compatibility with the Xbox 360.

Portal 2 has not been added to PS now so there is no way to play the game on the ps4. Since most people prefer to buy consoles for casual gaming, Valve would greatly benefit from bringing the game to the ps4 and ps5. Also the improved visuals would be appealing to players wanting to experience it for the first time. 

It would also be appreciated if Valve remasters portal 1 as well and bundles both the games together so that more people can play portal 1.
