About this game
SCP Containment Breach is a first-person survival horror game.
The events of the game take place in a containment site of The SCP Foundation, a secret organization dedicated to containing and researching anomalous artifacts and entities that threaten the normality of the world. You're thrown into the boots of a Class D test subject, one of the Foundation's disposable human guinea pigs.
Not long after receiving your first assignment, the facility undergoes a massive containment breach, leaving you alone in the darkness with the escaped entities roaming around the facility.
Your goal is to make it out alive. You can also search the facility for documents and other clues to figure out what led to the breach, and even attempt to do your part in fixing the situation.
The main antagonist of the game is SCP-173, an animate concrete sculpture that kills all living things on sight, moving toward its victims at a speed of several feet in one blink of an eye and snapping their necks with irresistible strength and lethal precision. Fortunately, SCP-173 has one key weakness: it is frozen in place as long as someone is looking at it.
To make things more interesting, SCP - Containment Breach has a blinking mechanic that forces the character to blink regularly (which often has fatal consequences in the vicinity of SCP-173).
One of the key elements of the game is the procedurally generated map - no playthrough is the same, and you can never know for sure what is going to happen next. There are plenty of obstacles to make the way out of the facility less pleasant. Decontamination gas that makes you blink faster, locked doors that require a key card with a sufficient security clearance or a specific access code to open, timer switch controlled doors, and of course, several escaped SCPs.
The level editor 3D World Studio is included, for creating your own custom rooms.

SCP Containment Breach on Steam
I'm pleased to announce that we are preparing to release SCP Containment Breach, the indie survival horror game originally released by Undertow Games, on Steam. The game was built on some of the technology I cut my teeth on, the late Mark Sibly's Blitz3D programming language and engine. My own editor 3D World Studio was used in the production of the game, although I was not involved in the process. The developer has graciously allowed us to curate the game on Steam, bringing this terrifying and unique indie experience to a new audience. I am also investigating how we can update 3D World Studio to run on modern Windows and include it as a modding tool for the game.Please add this free game to your wishlist on Steam now.Read full article on Community Announcements (Leadwerks Software)
