So i gave this a go tonight. I'm rubbish.
There was a few games where i and my team, had no footsteps at all. I think the other team did, but there was SOOO much camping going on, on both sides, it was difficult to tell. Other games seemed normal.
In a free for all match, footsteps were normal, except one guy who was completely silent, it seemed like the whole match but he could have been using dead silence, on repeat i guess. one other guy was silent too. Dunno if this is a bug my end or a perk of some sort. I havent had any audio issues in MW2,
Aim assist is still very strong. headshots seem to be more of a requirement as body shots seem to do less damage, which seems to make aim assist all the more obvious.
People seem more difficult to see, maybe i need to tweak some settings. i'm colour blind which doesnt help. The colour blindness settings are ok, but everyone uses them anyway, so still at a bit of a disadvantage. changes in colour dont stand out, only large changes in brightness, its difficult to explain to non colourblind folk lol.
i enjoyed some levels more than others. i havent played the old games, so none of these maps are familiar to me.
Frustratingly, it has carried across the weapons from the last game, but not the saved custom mods, dammit, i'll have to boot up the old one again and see what the attachments were.
jumping is too high still, like 5 feet in the air, ridiculous.
in game voices are still stupid "only a few in front of you now" when i'm very very last.
Overall though, i quite like it. hopefully once ive got the hang of it a bit, i wont suck so bad.... but probably will.
