CryZENx recreates levels, primarily from Nintendo 64 games, using the Unreal Engine, the same graphics engine powering modern games like "Bioshock: Infinite," and the "Batman Arkham" series. The levels can be downloaded and played on computers capable of running the Unreal Engine, but keep in mind CryZENx is just recreating these levels graphically, he isn't recreating any gameplay. That means no enemies, no other characters, and no story — just an open level reworked with modern graphics for you to explore.
To give you a taste of how CryZENx's recreations stack up against the original games, we've stacked the two side by side, and you can switch between the two by dragging the slider across the screen. What a difference new graphics can make.
