While there are minor hiccups concerning walking animations, and memory access violations, these problems are to be rectified in later installments of the mod. Most notably is the change of SCP objects and other personnel to monsters as stated above, each SCP/personnel has a unique model used that is entirely different than the core game. Also, most of the original voice actors have been replaced with new ones, two examples being D-9341's voice changing to a young Class-D child, and the security guards in the intro, amongst others. The mod features new textures and models for guard personnel, SCP's, items, room details. The goals are still the same as well escape the facility alive. Generally, the gameplay is the same in the mod as it is in the core game itself. In their efforts to survive the outbreak, D-9341 will encounter many SCPs, ones that can either help, hinder, or impede their progress altogether. SCP-173 will then proceed to kill the other two Class D personnel, and the scientist will announce a facility-wide lockdown. A voice over the intercom commands them to step closer towards SCP-173, only to be cut off. Upon entry to SCP-173's chamber, D-9341 spots two other Class D personnel. Within a few moments, guards open the door and request D-9341 to step out of their cell and perform a test with SCP-173.

The game starts with D-9341 waking up from their sleep and reading a document left for them on a table.
