It's crazy to see how much the visuals changed to fit the aesthetic. Like Vindicta at 1:56 was apparently a moth girl with glowing hair, and dynamo at 2:10 looks to be a japanese robot. It's really cool that Valve shared this.
I think the new aesthetic is honestly a lot better and sets it apart from other games. The cyberpunk/neon future aesthetic is kind of overdone at this point. Neon Prime looked more like Overwatch or The Finals.
That said the environment in deadlock is kind of dull compared to this. Too brown and grey with little variety. It's probably among the biggest complaints so I hope it changes a bit as development continues.
