Marvel Studios Avengers: Infinity War tickets are now on sale and there's a new trailer! After a decade of 18 movies, it's finally time for all of the heroes to face the biggest threat in the Marvel Cinematic Universe: Thanos.

MCU has built up the Infinity Stones since the beginning of the film series and every movie connects thanks to these six stones. Because the stones represent pieces of the universe, they carry a serious amount of power. So much power that it's pretty much the end of everything if someone has all of the stones. Gamora opens the new trailer describing just how dangerous Thanos can be if he gets his hands on all of the Infinity Stones. A simple snap can wipe out everything. He even threatens that he'll leave half of humanity once he's done.

Tony Stark, as always, has a plan. Thanos will come to them because they have two Infinity Stones in their protection. Star-Lord thinks he has a better plan that doesn't 'suck'. But now is not the time for disagreement because Thanos is going to be the most dangerous threat the Avengers have ever encountered.

Everyone's teaming up and getting ready for war. Thor's bringing the thunder with a new weapon, the Hulkbuster is back, and Captain America's got a new shield. We also see Doctor Strange screaming in pain and Thor and Cap directly encountering Thanos. Add that to the scenes from previous trailers of Peter Parker and Vision being harmed and it's no wonder Tony looks so visibly shaken! The battle scenes look epic and remind us that this movie will be unforgettable.
