Spawn Door Hold
After a full hold, holding line of sight on the enemy spawn exit and grinding down returning players one at a time.
An enemy with chained staggers comes back piecemeal, so pinning the spawn exit and processing them one at a time without letting them re-engage keeps a permanent 5v3 to 5v4. Where spawn camping is the concept of "the attacking side pushing aggressively right up to the spawn", Spawn Door Hold is fundamentally the posture of "fixing a line of fire on the exit after a full hold and cutting down whoever steps out" — the final form of a stagger snowball, put into words as positioning. It does not require pushing the front line far up; simply maintaining line of fire on the exit keeps the numbers advantage alive, so the execution cost is low while the call of "how far to push" is what matters. Learn it together with the play of locking the advantage in before the enemy is allowed a full regroup.
After a full hold, with staggers chaining, keep line of sight on the spawn exit and pick off returning players one at a time. Also effective when you need to buy time to lock the objective.
Pushing too far forward to hold the line of sight, stepping into the spawn exit area, and getting surrounded by the players who respawn. Or focusing so hard on the hold that you miss the timing to lock the objective, letting the enemy regroup and erasing the numbers advantage.
Stagger Snowball
A chain of staggers where one team can't regroup, losing 2–3 fights in a row before recovering.
Stagger
Delaying an enemy kill so they respawn out of sync with their team for the next fight.
Crossfire
Two or more shooters hitting the same target from divergent angles so no single piece of cover blocks both.
