Quick answer
Beginner killer struggles with generators finishing too fast.
What generator pressure means
Pressure is not just kicking a generator. It is making survivors choose between repairing, rescuing, healing, hiding, and running. The more urgent choices you create, the slower generators become.
Find the active side of the map
Survivors usually work around several nearby objectives. Check generators with progress, scratch marks, crows, and injured survivor paths to understand where the real match is happening.
Leave bad chases
If a survivor pulls you toward an empty corner and your important generators are far away, the correct play is often to leave and pressure the group.
Should killers always defend three generators?
Awareness is good, but hard camping a three-generator setup too early can waste pressure. Use generator clusters as a guide, not as your only plan.
