Mass Effect: Legendary Edition just released back in May, and the sci-fi series has been garnering a lot of renewed attention, including from developers who worked on the original trilogy. For example, a designer who worked on Mass Effect 3 recently unveiled an Easter egg that he put in the game that had never been discovered--it seems the developer was done waiting.

　　Cinematic designer Richard Boisvert posted on Reddit in May about the secret and gave some guidance to players who were interested in seeing it for themselves in the remasters. It's a cool little homage to a Mars rover, probably Opportunity, near the beginning of Mass Effect 3's Mars mission. If you follow a specific route, you can find a rover that'll drive over to you and give you a little nod.

　　While this is obviously just a cool gesture to NASA's Mars rover program, it's actually not that far-fetched that the little vehicles will still be around on Mars even as far in the future as 2186, when the game takes place. If no one removes them, they likely will still exist in some degraded form as monuments to past space exploration. Of course, it's impossible for it to actually be functional in 2186. Opportunity no longer works, while Curiosity and Perseverance will continue on for the next few years.
