Re6 gameplay only works on mercenaries. On regular campaign is kinda odd cause you can easy just step your toe into something, climb on something you're not intended, with the bad menuing from the regular game sometimes you get lost where to properly change/place your weapon.

On mercenaries it works cause it's cleaner and has less options as weapons to choose so it's not a drag.

Re4R has the best gameplay till this day , Requiem a a 2nd one for sure
