Mass Effect Andromeda: 15 Hidden Easter Eggs & Secrets You Need To Find

12. C-137 (Rick & Morty)

Three random numbers... or a specific three chosen to pay tribute to one of the finest ongoing animated shows in years?

I'm going with the latter, as 'C-137' refers to a large multiple dimension-focussed plot line in Rick & Morty - one that still has fans debating the differences between which timeline and universe various episodes in the show take place in.

C-137 tends to be the established 'main' universe, thematically tying into Andromeda being a continuation of the timeline established in the original trilogy.
