Warning of spoilers about the plot and game mechanics.
This panel’s presentation seems to be a pre-recording of actor Will Arnett and a representative of Rocksteady Studios. The reason it might be a pre-recording is the lack of any natural stumbling over words, and the interactions with voiceovers. Also, there is the use of green screens (which the Rocksteady representative mentions) to assist with various bits. Two such bits are the interactions with voiceovers, and the gag of Arnett teleporting. Whatever the case this is still more engaging and higher quality than the Comic-Con@Home panel pre-recordings.
Besides the gag of Will Arnett teleporting (twice) and supposedly talking to voiceovers of the characters there is also the trailer. This trailer occurs before Arnett’s interactions with the representative and his interactions with the characters. The trailer makes has three rather interesting things of note. First thing of note is Floyd Lawton alias Deadshot is more like the Will Smith interpretation since he is more overtly a braggart. While the second interesting thing is hearing former rap/hip-hop group OutKast’s song ‘B.O.B’ or ‘Bombs Over Baghdad’ (from the album Stankonia 2000). This is interesting due to how the song gives energy to the trailer, but is often misunderstood as intentionally being pro-war. The third is that Captain Boomerang seemingly is moving at super speed like his foe The Flash.
The trailer does not reveal much of the plot except for Superman’s foe Brainiac controlling the Justice League. Also the story scenes look much better than those seen in the video game Marvel’s Avengers (2020). After the trailer premiere we get an easter egg of the characters’ first appearance dates during Arnett’s interaction with them. Following this is when Arnett answers fan questions, and then essentially hands over the panel to Rocksteady’s representative. The representative talks up how the game is one to four players or even just single player with three characters the computer handles. Another thing the representative talks about is how the player(s) can switch between the characters during play. Finally this game’s story somehow connects to the video game Batman: Arkham Collection (2019).
