Yup, I cannot go back once I installed it. It is like the hardcore mode from LCPDFR but way better and with realistic ballistics and penetration and the whole nine yards. Amazing detail in the script and it makes every interaction tense due to it only taking one shot to kill you.
Sure, it's more difficult but the immersion is just something else. I used to drive around praying and hoping for like a crazy callout with a shootout or terrorist attack. Now, I pray for a quiet patrol and when I do take fire, I'm exceptionally mindful of taking cover and the type of cover I use. I remember once when I took cover behind the door of my cruiser but a single round went through the glass and hit the top bit of my head which just happened to be exposed. Instant death.
