Replicate! is designed to run on a custom game engine similar to a flying or racing game. The migration phase could be done with a 3D engine, but might also be rendered through a custom-built tunneling engine, such as that employed in the PlayStation title FreQuency. Relatively few polygons need to be rendered in this phase, although the gameplay is extremely fast.

The cellular attack mode could be rendered in a flying game engine, such as Homeworld. A 3D gaming engine such as Unreal could be adapted for this portion of the game, although the movement around the cell, when the player navigates around the cell surface to find a receptor point to enter the cell, could be awkward; most engines were designed with little movement along the Y axis in mind and thus the migration phase of replicate shares more in common with flying games than first person shooters.
