In the future, there are two big games set in the DC multiverse. The first is WB Games Montreal's Gotham Knights, a game in a new universe that focuses on the Bat-Family. The next is a new installment in the beloved Arkhamverse titled Suicide Squad: Kill The Justice League.
Obviously, this game focuses on the Suicide Squad and a storyline where Brainiac invades and turns the Justice League into his puppets. Fans are excited to see Rocksteady Studios tackle the Suicide Squad, especially after what they've shown so far. However, most can agree that things need to be changed from the previous games.
M For Mature
This is a game about a bunch of villains working together to stop a bigger evil. There's no need to pander to younger audiences: these villains should be allowed to show their full potential. They are all wielding guns and deadly melee weapons.
The animated movies were R-rated and even the new Suicide Squad sequel by James Gunn is going for a hard-R. Blood, gore, strong language, it would likely make for a unique experience. Batman: Arkham Knight barely scratched the surface with its M rating.
Looter Shooter
The gameplay for the Arkham games works for Batman. With a four-player co-op experience, the Arkham-style gameplay wouldn't really work. Instead, going off what the trailer demonstrated with each Squad member having a firearm and a melee weapon, Suicide Squad: Kill The Justice League could be a shooter.
Whether it's a first-person shooter like Borderlands or a third-person akin to The Division is up in the air. Either way, an open-world shooter with tons of side quests and daily generated missions could make the co-op experience fun. Add loot, gear, and other collectibles to make it even better.
Day To Night Cycle
Something the Arkham games really forced was the idea that each game takes place in a single night. That really doesn't make much sense considering how much Batman deals with in every game. Given that this will be an open-world co-op game with likely many different events and stories, it wouldn't hurt to have a day/night cycle.
It would feel more natural and allow for some nice visuals as gamers explore Metropolis. If The Legend Of Zelda can do it, so can Suicide Squad: Kill The Justice League.
Fast Travel
This one is going to be essential. At least with Batman, the gliding allowed players to get through the maps. Same with the Batmobile in Arkham Knight. However, characters like Harley Quinn and King Shark cannot fly or teleport.
Since traversing the maps in the Arkham games could get stale, having a fast travel system like in Batman: Arkham Origins would make things smoother. Especially since it looks like Metropolis is going to be massive.
Free DLC Content
Paying for extra content is not inherently bad: the Arkham games had great DLC to buy. That being said, this is going to be competing with Marvel's Avengers, another four-player co-op game. Despite that game's rocky launch, it is still delivering on its promise; all characters, stories, regions, and other non-cosmetic content has been and continues to be free.
So Rocksteady should be careful when it comes to Suicide Squad DLC. If every bit of DLC costs money leading to enough money to buy several games? Many players are going to be disappointed.
Multiple Online Modes
Cooperative modes, competitive modes, and the potential for having crazy villains like the Suicide Squad could make for many potential modes. A horde survival mode against Brainiac's forces like Call Of Duty: Zombies. How about a battle royale mode in which the closing ring is Brainiac extracting the city?
Even a typical team deathmatch mode would likely be fun with these characters. Having these alternate modes along with the expansive open-world campaign could give the game longevity.
Endless Side Quests
The side quests in the Arkham games are a bit of a mixed bag. Many are fantastic while others end as quickly as they begin. Once they and the story were complete, there was no incentive to keep exploring the maps. With Suicide Squad: Kill The Justice League, fans would love to keep playing.
The best solution would be to take inspiration from The Witcher III: Wild Hunt by giving them a seemingly unlimited amount of encounters that result in more quests. Plus daily and weekly objectives to make it so gamers put hundreds of hours into the game and still don't come close to 100% completion.
No Throwaway Characters
Trying to balance characters is hard in any game, especially in massive stories like in the Arkham games. That being said, some villains and characters were wasted poorly. Some even left the game after a single encounter, such as Hush for example.
With the DC universe, each famous character could make for hours of story and gameplay content. Having over-glorified cameos just makes the boss fight feel tacked on for padding rather than substantial content.
Character Classes
Sure, having multiple Suicide Squad members to play as will make for replayability. However, going back to what was said in a previous entry: why not make the characters like in Borderlands? Four unique characters but each one has multiple classes that can lead to different abilities, upgrades, and play styles.
What if someone wants to make Harley into an all melee fighter? Or put all of Captain Boomerang's focus into his gunplay? Or make Deadshot a supporter who heals teammates as he flies above? Lots of potentials that could make each playthrough dynamic and refreshing.
Character Customization
This is where Suicide Squad: Kill The Justice League could easily beat Marvel's Avengers. The biggest flaw gamers still have with that game is the gear system. The gear provides zero aesthetic changes, which is a massive missed opportunity and instead opts for serviceable skins.
Skins are not enough: even the Insomniac Spider-Man games with their good skins end up lacking compared to gear systems seen in Injustice 2. Gamers love to collect gear pieces and create their own characters. Skyrim, The Witcher, and even the newer Assassin's Creed games. This is where the looter shooter aspect would fit perfectly.
