It looks horrendous. Significantly worse than Gotham Knights in almost every metric.
Every bad choice and poor execution has been made. Gunplay looks and sounds like a paintball match. Absolute no weight to the recoil, and the enemies barely react to shots. Non-heavies are shrugging off minigun fire like it's nothing, and when they eventually go down, it looks like they have canned death animations. I didn't see q single instance of ragdoll physics.
The animation work is abysmal. Individual character movements are not high quality and barely in-character, but the animation blending and kinematics are where things really break down. Every movement looks like it's being performed on ice and without gravity. These characters are slide-dashing over more distance than Megaman.
Why is Harley Quinn, a normal human, basically standing in air with no locomotive signs of gravity or vertigo? Why is she getting insane airtime from her swings to zip over 2 city blocks, and landing from a story high without so much as a stumble? How is she doing all that with a minigun on her back? King Shark is double-air dashing with no force to accelerate, but why is Deadshot double jumping with a visual effect at his feet, and not with a quick burst of his jetpack?
The graphics look worse than Rocksteady's output from 2015. Mediocre textures, terrible particle effects and awful sound design on top of it.
And writing wise, it just looks utterly stupid.
"Flash is here and he's got Luther."
"One damn thing at a time!" Because Amanda Waller apparently can't address or consider more than a single variable at once, even though that's what her entire character is based around.
"Senseless violence, I love it!" Really, Boomerang? King Shark kicking the shit out of alien invaders who have very specific plans yo hollow out the entire planet is senseless violence?
"I love our escapades." Case closed on the dialogue.
The cutscenes are not well made. At the end, Harley fully opens both doors of the cargo box, waits until Lex comes to the threshold, stares at him without a word for a solid 2 seconds, and then hits him with dialogue, to which he has a delayed, stilted response. Flash, who has already let the Suicide Squad live despite being able to kill or debilitate them all in the blink of an eye, furthers the contrivances by spinning around in a big circle for 6 seconds before Wonder Woman makes her poorly shot and choreographed entrance, with her slightly androgynous design, constantly pouting/scowling facial expression and truly AWFUL and uncharacteristic voice acting.
The Suicide Squad is an almost universally unappealing concept, and the scenario that they've come up with here is inherently flawed. "We thought it would be interesting to show this world from the perspective of the villains." No you didn't. Otherwise, you would've made us play as Brainiac. Or better yet, not have the Suicide Squad be the heroes of the day.
The design makes no sense for these characters. "Harley Quinn is the most acrobatic", apparently for no other reason than her poorly animated cartwheels. Because there is no functional difference to any of these character's mobility. The loot is ridiculous. None of these characters are gunslingers other than Deadshot. Why is there a stock GCPD weapons in Metropolis? Why is King Shark wearing a Superman suit? What the hell were you thinking with this project, and how do you think it looks making the same promises as Avengers did not a month after they announce that game's effective end?
An absolute embarrassment for Rocksteady, and a waste of Eight. Years.
