One of the game's primary features is procedural generation of the facility. The player can save and load games depending on difficulty, with the game's medium difficulty only allowing saving at predetermined points and the game's hardest difficulty not allowing saving at all.

This mechanic is directly tied to SCP-173, who operates based on whether or not the player can see them. Throughout the entirety of the playthrough, the blink meter will gradually decrease and eventually force the player to blink, though the player can also blink on command. One of the characteristics of gameplay is the blink meter. The game plays from a first-person perspective with the player directly in control of D-9341, able to walk and sprint in any direction. During gameplay, the player roams the facility collecting items necessary to progress while being pursued by multiple SCPs and armed enemies, which must be avoided in order to continue playing.

The player controls a prisoner named D-9341 as they attempt to escape an underground research and containment facility amidst a breach of its numerous anomalies, known as SCPs. The game was released digitally on April 15, 2012, for download and was supported with digital content updates until its most recent update 1.3.11 on July 29, 2018.
