In conjunction with the debut of Epic Games' Unreal Engine 5, a new Tomb Raider game was announced. This engine has been accessible to developers for some time and has already been included in a few demonstrations, such as the Matrix Awakens city demo.
This new engine has been verified by a number of gaming developers, including Crystal Dynamics. UE5 will be used in the future Tomb Raider game. This means that Tomb Raider will be using a different engine than the Foundation engine, which is what most game developers are doing these days. CD Project Red has announced that they are working on a Witcher game that would run on the UE5 engine. It's just recently been confirmed that both are in development, fans of the series should be patient.
