Stop using doors. Seriously. The biggest hurdle in The Finals is unlearning years of FPS habits. If you need to get into a room, just blow a hole in the wall. The destruction isn't pre-baked animations; it's calculated on the server. Buildings crumble differently depending on where the load-bearing walls take damage. This completely changes defensive strategies. You can't just hold an angle when the angle itself might get deleted by an RPG. It forces a frantic, adaptive style of play that leads to some of the most ridiculous highlight clips we've ever seen.
