Fans were left with a lot of information in the Suicide Squad: Kill The Justice League trailer. For instance, the characters fight and show off how they move through long distances. Each one has been identified, and I'll explain how they will most likely move around Metropolis. Here is the trailer for anyone interested in following along:
A grappling hook is Harley Quinn's weapon of choice when fighting bad guys. Additionally, it's how she navigates the fight scene. We can therefore assume that she might use the grappling hook in the same way Batman did in the Arkham games.
Like Harley, Deadshot uses his transportation as a weapon. The trailer shows him roasting people with his jetpack and navigating a fight scene with it. In Suicide Squad: Kill The Justice League, it's natural to assume that Deadshot might have a jetpack with limited use.
King Shark is a larger and heavier character. Compared to other characters in the trailer, he seems to move less dynamically. I assume that King Shark will be more of a tank character in the game, and this is how we can assume his means of transportation. Using his strength as an advantage, king shark could be like the Hulk.
In Suicide Squad: Kill The Justice League, Captain Boomerang is one of the more interesting characters. His means of transportation is his weapon, just like every other character's. When he throws a boomerang at its intended destination, he somehow teleports to it. This is like the grappling hook, only a lot cooler. Although he seems to be able to travel more interestingly than the others, there must be more to it.
