10 Completely Insane Video Game Details Nobody Noticed
2. BJ's Tattoo Spells "Doom" Numerically - Wolfenstein: The New Order
Though it's no secret that the Wolfenstein and Doom franchises love to drop references to one another - both of them having been created at id Software and all - Wolfenstein: The New Order includes an especially subtle one you'll kick yourself for not noticing.
After B.J. Blazkowicz infiltrates the Nazi death camp Belica, he receives an identifying arm tattoo which contains the numbers "4, 15, 15, 13," which at first glance seems like a mere random string of numbers, right? Wrong.
If you convert those numbers to letters, they read out, "D O O M," creating yet another enticing link between the legendary FPS protagonists.
In more recent years, designer John Romero has even gone further as to suggest that Blaskowicz and Doomguy are related, having the same lineage both literally and spiritually.
