Where to find 40mm PO-X Grenade in DayZ
40mm PO-X Grenade is the in-game name; server files such as types.xml call it Ammo_40mm_Chemgas.
On Chernarus, the economy keeps about 5 on the map and spawns more when fewer than 3 are left, after waiting 30 min. Each one lasts 1 h 30 min when nobody touches it. It spawns in ContaminatedArea places.
On Livonia, the economy keeps about 4 on the map and spawns more when fewer than 2 are left. Each one lasts 4 h when nobody touches it. It spawns in Underground places.
On Sakhal, the economy keeps about 4 on the map and spawns more when fewer than 2 are left. Each one lasts 4 h when nobody touches it. It spawns in Military places, in Tier4.
On Nasdara, the economy keeps about 5 on the map and spawns more when fewer than 3 are left, after waiting 30 min. Each one lasts 1 h 30 min when nobody touches it. It spawns in Military places. It also comes from dynamic events such as helicopter crashes.
Where to look
- Contaminated zones (ContaminatedArea)
- Underground bunkers (Underground)
- Military bases, camps and checkpoints (Military)
Loot tiers: Sakhal Tier4. Tier1 is near the coast and Tier4 deep inland, so a higher tier means a longer trip.
