I'm 100% certain that it's been in the game since release. I remember when the game came out, everyone was complaining that
the game really only had 3 endings, and they all looked the exact same, just different colors.In fact...
*Checks Google Images*
Yup, I remember seeing this a couple days after the game was released (might contain spoilers for the third game, if anyone cares):
I also remember the indoctrination theory, one of the more accepted theories that tries to make sense of the ending, said that
the synthesis ending was a reference to Saren from the first game, while the control ending was a reference to the illusive man.But yeah, I'm certain it wasn't added by any DLC/update.
Ok. He must have thought there was just A and C and the middle wasn't one of them... I guess? XD
