Smektala shared that instead of using the old game engine they used for the original game, they have their own in-house engine called the C-Engine. At the very beginning of creating Dying Light 2 Stay Human, they made sure they changed their technology. It also has a great benefit for them and the game, which was its extreme scalability.
The benefit that the C-Engine offers is its scalability. It will allow them not only to create the game for PS4, but also on the PS5, and the possibility of the PS6 and so on and so forth. It can be scaled towards the latest type of hardware and will still be compatible to it.
The pandemic made a lot of studios have to release a game on last-gen and new-gen consoles, but Techland was prepared, according to Smektala. They already had the technology that made sure they could do that.
Also, Techland made sure that they did not skimp on the features on the PS4 build. Except for the Ray-Tracing and other high-end stuff, the gameplay experience is still the same between old-gen and new-gen versions.
