Far Cry 5 has some dark and gritty moments as you infiltrate a doomsday cult, but much more of the open-world exploration is light and even wacky. That extends to the Easter eggs Ubisoft inserted into the game, which reference other Ubisoft games, Uwe Boll, and even President Trump.

Many of the references to other Ubisoft games are kept in the family of Far Cry itself. You can find bobbleheads of characters like Vaas (Far Cry 3) and Pagan Min (Far Cry 4), and cave paintings as a subtle wink toward Far Cry Primal. Plenty of references are also made to the sci-fi spin-off DLC, Blood Dragon. You can find a movie set for making the campy schlock-fest, or dress up as one of its Cyborg Soldiers.
