Best World Settings for Tactical Shooter

Hello!

I am making a tactical shooter and was wondering what I should use for my world settings?

Currently I am using the action preset but I think that the players are too fast and can jump too high and it becomes a run and gun game which is not what I want.

(PS: By world settings I mean jump power, walk speed, gravity, etc.)

Just tinker around with the settings, continue to change them and test around until you get something you like, it will be different for every person
