Strata Source (more informally known as Strata, and formerly known as the Chaos Engine) is a third-party 
Source engine branch using licensed code. It is a modified version of the 
CS:GO engine branch that combines the features of both CS:GO and the 
Portal 2 engine branch, along with many improvements that bring Source close to modern standards. This engine branch was first released publicly with the launch of 
Portal: Revolution, and is still in active development.
Features

New since the CS:GO engine branch:
