PUBG Mobile 39.1 introduces the BZ Grenade Launcher alongside traditional BZ Grenades in frozen Erangel: Subzero (released December 4, 2025). These area denial weapons create freezing damage zones with 10m radius dealing 10 DPS, persisting for 15 seconds. Optimal builds carry 2-3 BZ Grenades or Launchers with primary weapons like M416 or VSS, 6-8 healing items, and 150-200 rounds for late-game chokepoint control in competitive squad play.
Understanding BZ Grenades: Core Mechanics
BZ Grenades weigh 15 units each, feature a non-cookable 2.5-second fuse, and create a 360-degree expanding mini blue zone. The zone follows a precise 15-second lifecycle: 5 seconds expanding, 5 seconds fully expanded, 5 seconds shrinking.
Damage Output:
10 DPS over 15 seconds (150 max damage)
10-meter blast radius (314 square meters coverage)
Frag Grenades: 100 instant damage
Molotovs: 12.5 DPS
BZ Grenades: Superior for sustained denial vs instant elimination
The freezing effect can't be blocked by Jammer Packs, forcing enemies to evacuate or sustain continuous damage. BZ Grenades spawn at satellite crash sites: Stalber, Shelter, Sosnovka Military Base, and Boatyard.

Cold Damage System
10 damage per second applies uniformly across the entire 10m zone regardless of player positioning. Unlike Molotov fire damage, cold damage can't be mitigated by movement.
Phase Breakdown:
0-5 seconds: Expansion (enemies can retreat with minimal damage)
5-10 seconds: Full expansion (maximum denial effectiveness)
10-15 seconds: Shrinking (brief windows for aggressive pushes)
BZ vs Traditional Grenades
Frag Grenades:
100 fixed damage, instant elimination potential
No sustained area denial
Enemies immediately reoccupy positions
Molotov Cocktails:
12.5 DPS, smaller coverage
Visual fire telegraphs denial zones
Less effective than BZ in Season 39.1
BZ Grenades:
Excel in final circles, building holds, chokepoint defense
314 square meters coverage vs Frag's smaller kill radius
40-50 meter throwing range with aimed arcs
Erangel Subzero Meta Shift
December 4, 2025 update fundamentally altered competitive meta. Ice surfaces reduce vehicle handling by 20-30%, forcing more infantry engagements where BZ Grenades provide maximum value. Disabled Red Zone makes player-controlled denial the primary area control mechanic.
BZ Grenade Spawn Rates:
Boatyard: 28% increased BZ Grenade Launcher spawns
Military Base, School, Pochinki: 30-40% spawn probability
Satellite crash sites: Consistent spawns at 4 major locations
Season 39.1 Map Changes
Footprint Tracking:
Persists 10 minutes with audio cues
Makes stealth approaches difficult
Favors defensive positions with BZ denial zones
Penguin Snowmobile:
85 km/h on land, 65 km/h on water
20-30% handling reduction on ice
Increases value of infantry-based denial tactics
Competitive Meta
Squads prioritize 2-3 BZ Grenades or Launchers, 6-8 healing items, 150-200 rounds. BZ Grenade Launcher occupies secondary weapon slots—squads running dual launchers sacrifice close-quarters flexibility for maximum area control.

Common Mistakes and How to Avoid Them
Overcommitting Inventory Space
Problem:
4+ BZ Grenades creates healing deficits
Fatal in extended engagements
Solution:
2-3 BZ Grenades provide sufficient denial
Maintain healing sustainability with first aid kits and med kits
Poor Throw Timing
Problem:
Throwing before confirming enemy positions wastes resources
Premature throws allow enemies to wait out 15-second duration
Solution:
Require visual confirmation or reliable audio cues
Coordinate throws with squad pushes for active engagements
Ignoring Environmental Factors
Elevation Differences:
Uphill throws require increased power
Downhill throws need reduced power to prevent overshooting
Building Interiors:
Account for ceiling heights and doorway clearances
Grenades bouncing off unexpected surfaces create self-inflicted denial
Failing to Combine with Other Utility
Problem:
Isolated BZ throws allow consequence-free evacuation
Solution:
BZ forces movement → Frags punish evacuation routes → Smokes conceal friendly advances
Chain multiple throwables for no-win scenarios

FAQ
What is the BZ Grenade damage radius in PUBG Mobile 39.1?
10-meter blast radius dealing 10 DPS for 15 seconds (150 max damage). Zone expands over 5 seconds, remains fully expanded for 5 seconds, then shrinks over final 5 seconds.
How many BZ Grenades should I carry in Erangel?
Carry 2-3 BZ Grenades alongside 6-8 healing items and 150-200 rounds. This provides sufficient denial while maintaining combat effectiveness and healing sustainability.
Does BZ Grenade work better than Frag in Season 39.1?
BZ Grenades excel at sustained area denial (10 DPS over 15 seconds, 10m radius) for final circle control and building holds. Frags deliver 100 instant damage for immediate eliminations. Use BZ for denial, Frags for kills.
Where to find BZ Grenades in Erangel Subzero?
Satellite crash sites at Stalber, Shelter, Sosnovka Military Base, and Boatyard. Military Base, School, and Pochinki offer 30-40% spawn rates. Boatyard provides 28% increased BZ Grenade Launcher spawns.
What is the best BZ Grenade build for squad mode?
One grenade specialist carries 3 BZ Grenades with M416 and VSS. Remaining members carry 1-2 BZ Grenades with balanced healing and ammunition. This concentrates denial capability while maintaining squad combat effectiveness.
How to counter BZ Grenade area denial tactics?
Immediately evacuate upon detonation (30-50 damage during 5-second expansion). Use Smoke Grenades for concealed evacuation, or push aggressively through expanding zones to surprise enemies. Vehicles bypass denial zones despite ice handling reductions.
