Strata Source Strata Source, formerly known as the "Chaos Engine", is a third-party Source engine branch using licenced 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 is still in active development.
