Re: I would like to see the game recreated from scratch in the source 2 engine

It's been requested a number of times, on many different engines. Regalis' official statement is that he's shifted focus to Barotrauma, because when that gets released on Steam, that will actually help pay his bills and what-have-you. SCP Containment Breach was a game he made for fun, and for a Blitz project, it's gotten way too large to be stable. The code is an absolute mess, and besides that, the game is fundamentally terrible. To remake the game from scratch would be a huge waste of his time. There's a Unity port in the works, but zornor90 is doing that one.

If you want it on the Source 2 engine, you could take the endeavour yourself.
