In some art for a new Avengers: Age of Ultron official LEGO set, the toy set descriptions reveal many new spoilers concerning the sequel’s plot.

As is often the case with franchise films, The Avengers: Age of Ultron’s release will be accompanied by an official LEGO set. The art for the set include some descriptions for the set which reveal spoilers for many of the film’s fight sequences.

One of the many speculations about the film’s trailer has been whether the Hulk is under someone else’s control during the Hulkbuster fight scene between him and Iron Man. In the trailer we saw that the Hulk’s eyes were a bit red, and in one of the descriptions below we find out exactly why. If you don’t want to read any spoilers for the film, please don’t read the descriptions below:

First up is the attack on the Avengers’ tower party, which we’ve seen in both of the film’s trailers. The description explains that Ultron assembles himself in the lab in one of the building’s levels, and even says that some of the team will be injured during the battle. This could be specifically for the LEGO set, but it’s possible that it does follow the film’s actual storyline.

ATTACK ON AVENGERS TOWER (76038)
The Heroes are having a party when suddenly Avengers Tower comes under Ultron’s attack from the inside! Evil Ultron Mark 1 has assembled himself in the lab and is exploding out the windows. Help Iron Man and Thor to defeat Ultron and the 2 Iron Legion accomplices under his control. Make plans in the JARVIS control room and treat injured Superheroes in the sick bay. An Iron Legion is blasting out the doors and windows of the ground-floor robot bay. The other has stolen the Loki Scepter from the analysis lab so pursue him with Thor and take aim from the roof of the tower with the secret hidden drone and stud shooters. You must retrieve the Scepter and stop Ultron! Includes 5 minifigures with a weapon and assorted accessories: Ultron Mark 1, 2 Iron Legions, Iron Man and Thor.

In the next description we see what is the Quinjet chase sequence, which is shown in the trailer, where we see Black Widow fall from the plane onto the ground with a motorcycle. It looks like the sequence is when the Avengers are chasing Ultron and some “precious cargo,” but we’re unsure what that cargo will be. Maybe it’s his precious vibranium he plans on coating himself with.

THE AVENGERS QUINJET CITY CHASE (76032)
Launch a high-speed pursuit of Ultron with the Avengers in the iconic Quinjet. Place Black Widow at the controls in the cockpit and soar into the sky. Fire the stud shooters and release Captain America on his super-cool bike to take the pursuit to the streets. Iron Man MK43 is flying alongside the Quinjet using his thrusters, ready to take on Ultron. When the time is right, make the perfect jump onto the truck to explode the sides and reveal the precious cargo. Includes 5 minifigures with assorted accessories: Vision, Captain America, Black Widow, Iron Man and Ultron.

The Hulkbuster fight has been the talk of the trailer, as Hulk and Iron Man battle it out in the streets in what looks like one epic fight sequence. In the description we find out that Scarlet Witch has Hulk under her control, and Iron Man is using his Hulkbuster suit to try and stop Hulk while he’s under Scarlet Witch’s control.

HULKBUSTER RESCUE MISSION/ THE HULKBUSTER SMASH (76031)
Hulk has been trapped by the powers of Scarlet Witch and she is ready to fire an electrical bolt if he tries to escape! Place Iron Man in the cockpit of the humungous Hulk Buster suit and rush to the rescue. On the way you must fend off aerial attacks from the flying Ultron. Adjust the Hulk Busters arms and legs to create fearsome battle poses and grab the villain with the powerful hands. With Ultron safely in the mechs grip, attach Iron Man to his Super Jumper. Then take out Scarlet Witch with an accurate jump and free the imprisoned Hulk! Includes 3 minifigures with assorted weapons and accessories: Iron Man, Ultron and Scarlet Witch, plus a Hulk figure.

The next description talks about Thor and Hawkeye working together as they chase down the “Hydra henchman” through the forest of Sokovia. While we do see Hawkeye in a forest at one point in the trailer, the rest of this description is difficult to decide whether it’s something we’ll see in the film or just made for people to have fun with while using the LEGO set.

DUEL WITH HYDRA/ HYDRA SHOWDOWN (76030)
Join Thor and Hawkeye as they chase the Hydra henchman through the Sokovia winter forest! Place Hawkeye in the cockpit of the awesome Avengers 4×4 vehicle and accelerate away. When you have the Hydra offroader in your sights, fire the flick missiles from the rotating turret and swerve away from the offroaders powerful stud shooter. Then launch Thor on his Super Jumper and disable the stud shooter with one perfectly aimed jump! Includes 3 minifigures with assorted weapons and accessories: Thor, Hawkeye and Hydra henchman.

The final description talks about Iron Man fighting Ultron in the “ultimate battle.” It seems as though there will be a very large aerial attack when Ultron releases his minions upon the Avengers, and this is something we saw in the recent Age of Ultron trailer.

IRON MAN VS. ULTRON (76029)
Team up with Iron Man MK45 to take on the Ultron army in an ultimate battle! Defend against aerial attacks from the Ultron vehicle piloted by the Sub-Ultron officer. Take cover as Sub-Ultron troopers leap from the back of the vehicle and fire their stud shooters. Then activate Iron Mans Super Jumper to topple the Sub-Ultron officer and bring the vehicle crashing to the ground! Includes 4 minifigures with assorted weapons and accessories: Sub-Ultron officer, 2 Sub-Ultron troopers and Iron Man MK45.

We’re unsure how Marvel feels about The Avengers: Age of Ultron’s plot details leaking months prior to the film’s release, but we imagine many of these descriptions have been altered to give people who plan on buying the LEGO set something to do with each set.

Let us know what you think of the set itself, and whether you’re interested in what we’ve now found out about The Avengers: Age of Ultron. The film will hit theaters May 1, 2015.
