The trailer for the fourth Avengers film - Avengers: Endgame - is finally here.
It's a pretty depressing trailer, focusing mostly on Tony Stark drifting through space and preparing to leave a farewell message.
The action cuts back to Black Widow and Captain America, who face the reality of Thanos wiping out half the life on the planet.
"We lost, all of us," Captain America says.
"We lost friends, we lost family, we lost a part of ourselves. This is the fight of our lives."
It's met with appearances from Bruce Banner and Hawkeye, as well as a scene from Ant-Man towards the end.
It's a pretty gloomy trailer, but it's well worth the watch.
