SCP crapstainment breach is a mod made in a week, entirely in MS Paint. it is complete garbage, and it contains custom sounds and graphics. if i feel like it ill update it. has light, heavy, and entrance zone.
To play, just download and unzip the file. Then run the file called "SCP - Containment Breach Ultimate Edition v220.127.116.11."
Contains changes to many walls, some sounds, NPCs, etc etc.
