This is a **list of all of the versions** of *SCP - Containment Breach* that were released, listed in chronological order.

The downloads to all of these versions can be found in this archive.

# Indev Versions

Prior to the release of v0.1 of *SCP - Containment Breach*, Regalis had been releasing various screenshots and demonstration videos of the game, showing off different aspects of it that he was working on. All of these videos contain many differences from the released versions of the game. Regalis has stated that he does not have any of these indev versions anymore.

* Buttons have a different model.
* There's no hand icon for pressing a button or picking up an item.
* SCP-106 has a different spawn sound.
* There is a sound effect for when SCP-106 passes through matter.
* The lockroom had no decontamination gas in it.
* The CCTV monitors used a stretched out version of the original S-Nav texture.
* SCP-173 has a different model and sound effects. The model can be found in the game's files under `SCP - Containment Breach/GFX/npcs/173.b3d` from v0.1-0.1.2. The stone dragging sound effect can be found under `SCP - Containment Breach/SFX/StoneDrag2.ogg` from v0.1-1.3.1.
* The blink and sprint meters were actually dynamic instead of using a series of static sprites to represent them.
	+ Both meters turn red when they are low.
* Old door texture.
* SCP-173's old model.
* The storeroom contains a refrigerator in the center of it.
* D-9341 yells when he dies.
* This version didn't have any SCP signs on containment chambers and merely showed a white sign with the SCP's number on it.
* Large containment doors had a different model, texture and sound effect.
* SCP-895's observatory room had a different computer monitor, most notably it included a mouse.
* The decontamination gas doesn't cause the player's blink meter to deplete faster (although D-9341 still coughs and the blink icon is still outlined in red).
* Getting killed while wearing a gas mask would cause blood to splatter on the visor. The texture for the blood can still be found in the game's files under `SCP - Containment Breach/GFX/BloodOverlay.jpg` from v0.1-0.2.

	+ The radio's assets can still be found in v0.1, albeit with a different appearance, meaning that it could've simply been un-finished during the initial release.
* The HUD sprite for the radio found in v0.1.
