I like how you can see Quan Chi's real skin color after you've put the beat down on him.

The stone depiction of the Elder Gods and Raiden trapping Shinnok on the wall of the Jinsei Chamber.

That's awesome about the MK3 music. Haven't come across that yet.

There is so much detail in this game..I dont even know where to begin..

I like that there's a crow that comes and sits on the body after Erron Black's brutality. It flies away after a second, it's a nice touch. I don't know if it's just for his brutality though

I also like the depiction of the Elder Gods in Quan Chi's ending. The one with the mask/cape looks fucking awesome, they should make him a playable character. lol

Erron Black having a bullet with "your name on it." Seeing your opponent's nameon it is so cool. I also love the MK3 music Cassie listens to in her intros. Ironca, since her pa wasn't even in MK3.

How the fighters start to sweat when the fight is over

I was online and I saw a quote from The Mortal Kombat Movie pop up in the online menus where the tips are.

Kitana's advice to Liu on defeating Sub-Zero.

There are so many to list from the Krypt but my favorite is that people paid $20 to unlock everything and there are still secrets in the Krypt!!!!

the Spiked pit secret for example

In the destroyed City. There is a guy in the background having a fight with some stray dogs....he is shooting them with a gun strangely to no avail. Then by the end of my fight I noticed he was dead and was being dragged off by one of the pooches.

I found this kind of funny.

Then at the Refugee camp... all starts off well and good...people coming in etc. Then later on I notice a Tarkatan Warrior come out and walk off with a refugee back through the portal.

Here's a neat little detailed that I noticed is missing!

You know when you play arcade mode against corrupted Shinnok and loses, he walks with your head and throws it.

But with Ferra/To.... Wait a sec.

He only carries Torrs head. It would be a neat little detail if Ferras head was attached with a thread next to Torr or if Shinnok carried Ferras in his other hand.

I really like how D'Vorah has those two insect arms that comes out of her back.
I'm pretty sure NRS used the concept art for that dancer they has in MK:DA. The one with the spiked ribbons on her back.

Kira got a little nod and is confirmed alive in one of the hourly towers I did a while ago. It was the laser one.

I think it was the special forces stage, a portal opens in the background and a Tarkatan comes out of it and the troops attack him and drag him away (something like that). You can hear Cassie listening to MK 3 music on her head phones. Oh and those alligators swimming in the river in the Kuatan Jungle

Ninja Mime Johnny Cage is mimicking the cell phone animation on the select screen without actually having a cell phone

This.

If you have the White Lotus backround, the characters on the select screen start to get wet in the rain.

The AI in Tower fights will have alternate costumes on occasion...if you unlocked them.

When the four heroes are in Outworld during Kung Jin's chapter, you can see a lot of the locals looking at them cautiously in the background, like they're outsiders. Some even look angry that Earthrealmers are there.

Cassie Cage Selfie Fatality on her "Friendship" page Noobde comments: Did anyone unlock Fujin Yet?

D'vorahs animation for losing a round makes her act like a dead bug.

A lot of them have already been mentioned in here. But I'm playing te Klassic ladder with Quan Chi and my first flight was against Sub. And after I beat him in the first round he says "your brother had more heart". Thought that was cool.
