You really got me when you said you could play as Barracho in area 51 I fall for it at first intill I found out it was a joke Mortal Kombat 4 is the best arcade mk game of all times I wasn’t around in 1997. I wasn’t even a thought but I got to play the PS1 version and the PC version of the game
In Unreal Championship 2, you get 2 different announcers. The default one from Unreal Tournament 2003 and the Mortal Kombat Deception/Armageddon announcer. Plus, you can also unlock and play as Raiden.
You forgot tony hawks underground. On the map Moscow there’s a snow man and if you manage to knock off only his head the snow man will gush out blood and you’ll get the gap F A T A L I T Y !!!
There are other Easter Eggs from Mortal Kombat - NBA Jam TE where you can play as Sub-Zero, Scorpion, Raiden, and Reptile, though they took it out after 2.0 since the NBA didn't want that kind of game to associate with them. There's also The Grid, Unreal Championship 2: The Liandri Conflict. Batman: Arkham City Lockdown (Kano), Injustice 2 (Raiden + Sub Zero), Broforce (Raiden), NBA Ballers: Phenom, though they're just background cameos.
You forgot the NBA Jam game it was published by Midway in the 90s, however, the NBA told Midway to take out the Mortal Kombat II characters of Rayden, Scorpion and Reptile from the game.
....Let us not forget NFL BLITZ, where we could be Sub, Scorp, and Rayden....Also unmentioned was N.B.A. Jam, as we could play as some of the MK kast...Like u sed tho, those are also Midway games, and I for one, loved that Midway did this...What if midway redid the game called War Gods??? U kno our boy Kretos would fit right in...Midway???? This ideas for you!!!!!
*MLB Slugfest: Loaded* would've been wild and more famous if it featured a code to play as the *Mortal Kombat I* cast (Kano, Liu Kang, Raiden, Johnny Cage, Scorpion, Sub-Zero, Sonya, Reptile and Goro); with another code to play as the *Gauntlet Legends* cast (Warrior, Minotaur, Wizard, Jackal, Sumner, Archer, Tigress, Valkyrie, and Falconess).
Psi Ops Mindgate Conspiracy and Second Sight came out around the same time they both had similar ideas and possibly even similar mechanics I don't remember Psi Ops all that much because I only played a demo of it back in the day were I actually still have the copy of Second Sight but when I played of the demo it looked like it was extremely fun
