Collapse
Multiple players converging from different angles to instantly surround and eliminate one target.
If Dive is the entry onto a target, Collapse is the closing phase after entry, where everyone's angles and damage converge onto a single point. Closing in piecemeal gets you picked apart one by one; a synchronized collapse strips the enemy of escape routes and cover at the same time. It shows up most often right after taking a numbers advantage, cleaning up the remaining enemies as fast as possible to lock that advantage in. One second of timing drift and the whole team gets picked apart one by one.
Right after a pick, with the enemy at 5v4. Cleaning up the survivors immediately after the first kill of a fight. The moment a target isolates while you are running Dive.
Closing in piecemeal and getting picked apart one by one. Collapse timing not lining up, so one player goes in alone and dies. Forcing the collapse while the enemy still has Suzu/Immortality up.
Dive
High-mobility composition that bursts down enemy supports and disengages immediately.
Pinch
Pressuring the enemy from two directions at once, splitting their sightlines and escape routes.
Wombo Combo
Stacking multiple ultimates within one second to bypass defensive cooldowns and wipe the team.
Crossfire
Two or more shooters hitting the same target from divergent angles so no single piece of cover blocks both.
Numbers Advantage
Outnumbering the surviving enemy (e.g. 5v4). The baseline from which all fight risk is calculated.
Pick
A solo kill before or at the start of a fight that gives your team a numbers advantage going in.
