9. The Terminator's Fake DLC Roster - Mortal Kombat 11
Sometimes gamers are perhaps a little too inquisitive for their own good, or so developers think, especially when it comes to datamining game code to figure out what DLC might be releasing next.
That's exactly what happened with Mortal Kombat 11, resulting in the full roster for its first Kombat Pack - including Shang Tsung, Joker, Nightwolf, Terminator, Sindel and Spawn - being leaked before NetherRealm ever made an official announcement.
But the developer perhaps got the last laugh, then, by hiding an intentionally misleading Easter egg within the Kombat Pack which only the most eagle-eyed of fans would ever notice.
Basically, one of the Terminator's victory outro sequences shows it scanning the corpse of its fallen enemy (7:00 in the below video), and anyone paying extremely close attention to the upper-right corner will briefly see a list of characters for Kombat Pack 2 listed.
The roster includes Mileena, Rain, Li Mei, Sareena, Meat, and Mokap.
Considering that the latter two are effectively joke characters, it soon enough became clear that this list was a fake intended to poke some harmless fun at those keenly scanning every last inch of the screen looking for secrets.
Well played, NetherRealm.
