Agree on that, maybe make the "Classic" scanning faster, and not disappear completely.

Just don't upgrade the scanning, and you will have the movie accurate version when marking enemies.

I would have loved to either have the mark enemies feature on a separate button from the aim button, or have that feature mark automatically. I absolutely despise that the game forces you to have to aim in order to be able to mark enemies. It really breaks the fluidity of the shooting mechanics, and does not make any sense at all to the movies. Robo never had to aim his Auto-9 on targets to mark/register them.

And yeah, I know Rogue City is a game and not a movie, and Teyon wanted to somehow make the mark feature into a gameplay feature. But in that case, they should have dedicated a button to it instead of mixing it together with the aim down sights button. Just imagine how much better and more fluid the shooting mechanics would be if you could mark enemies without having to aim down sights.

And by the way, it's useless to ask Teyon of anything (trust me I've tried several times).
They don't care about Rogue City anymore. The game has had it's 1st year Anniversary, and still no DLC at all whatsoever.
