This page may or may not be about Source 2. The page makes it unclear whether or not it is supposed to be on the Source SDK section

This article or section needs to be cleaned up to conform to a higher standard of quality.
For help, see the VDC Editing Help and Wikipedia cleanup process. Also, remember to check for any notes left by the tagger at this article's talk page.

Im not really qualified in writing wiki pages, im just adding this here so if someone has the same question I did, they can find the answer, until someone better than me at this cleans up this page and brings it up to standard. Thanks to Adesi on the Alyx modding server.
