Don't worry, there are no Endgame spoilers here. For more on the movie, check out our Avengers: Endgame review or read some reviews from around the industry.
Avengers: Endgame marks the 22nd movie in the MCU and the first time in the shared film universe that will not have a visual sequence tacked on to the end, teasing what's next for Marvel. However, there may be a reason to stick around as there is an audio stinger at the end, when the Marvel logo appears. The metal hitting metal sound is open to interpretation, but it's been suggested it sounds like Tony Stark forging his first Iron Man armor. So as soon as the credits begin to roll, the choice is yours. You can leave the theater or stay through the credits to hear a noise that may or not mean anything.
Endgame is the end of Phase 3 of the MCU, and as we learned last month, those 22 films will be known as The Infinity Saga. As far as recent mid-credits and post-credit sequences go, Infinity War ended with Nick Fury contacting Captain Marvel on a pager, Ant-Man and the Wasp left Scott Lang trapped in the Quantum Realm with his friends snapped to dust, and Captain Marvel showed us Carol Danvers answering the pager's call in the present, meeting the Avengers. Additionally, there were a couple of comedic post-credit moments as well.
Some of these sequences give the audience a hint as to what's coming next. But with Endgame being the end of the 22-film journey, there's nothing left to tease before Phase 4 begins--although Marvel boss Kevin Feige has clarified that Spider-Man: Far From Home, not Endgame, is technically the end of Phase 3. So perhaps some hint as to what is to come will be delivered there, once the movie is released in July.
In our Endgame review, GameSpot's Mike Rougeau wrote, "Endgame is truly a love letter to the entire MCU--the whole thing."

It's spoiler-safe, giving just vague allusions to what events to watch for when you step out to relieve yourself. At just over three hours long and the stakes being so high, no one will blame you if you need a quick bathroom trip.
