First match checklist
Your first goal is not perfect play. Learn what role you spawned as, where nearby cover sits, and how quickly the hunter can punish open movement.
If you are a survivor, survive the timer and avoid exposure. If you become the threat, search likely hiding routes and close distance quickly.
Keep the camera angled toward open lanes and corners so you can react before the hunter reaches melee or laser pressure.
Crouching reduces noise and helps when scan pressure is likely, but do not crouch so long that you trap yourself.
