Simulacrum

The Simulacrum is a wave based alternative gamemode that is new to The Survivors of the Void update and DLC.

When you spawn in for the first time you will be the character you selected and you will spawn next to an object called The Assesment Focus. The Assesment Focus that acts much like the cells in the void fields. Each wave will spawn a certain amount of enemies indicated by a bar where the difficulty bar would be located in a normal run, after each wave an item of different rarities will eject out of the assesment focus that lets you chose three items, acting like the Artifact of Command, then a timer starts for 10 seconds that starts the new wave. After a certain amount of waves there will be a boss wave where "Enemies are stronger and more numerous." after defeating this the orb in the center will levitate and move to a new part of the map.

Items that activate during the teleporter event activate during the waves.

As of version 1.2.1.0 (Release) the gamemode is bugged and has a chance to cease enemy spawns, causing a softlock.
