Iron Trials '84 was a game mode limited to duos in Verdansk '84, which was later also available as solos, trios or quads and appears every now and then in Warzone's playlists. Just recently, the mode also introduced on Rebirth Island and now finally has arrived in Caldera. With Season 3, all sweaty players can finally play the ultra-competitive BR mode on Caldera as well. Since probably still not everyone knows how Iron Trials differs from the normal BR mode, we explain all the rules here.

The Caldera Iron Trials Rules


  • More Cash after death: Those who die in Iron Trials keep a little more cash than usual after their revive.
  • Reduced melee damage: Melee finisher damage is capped at 150.
  • No free loadouts: No free Loadout Drops — those who want to use their custom-built weaponry and gain access to Perks will need to purchase one at a premium. [$15,000]
  • Vehicles: Only ATVs, Tac Rovers, and Squad Transports are available.
  • Buy Stations: Elite Operators are known to be high rollers. The Buy Station increased their prices accordingly:
    • Armor Bundle: $1,500 to $2,000
    • Gas Mask: $3,000 to $4,000
    • Cluster Strike: $3,000 to $4,000
    • Precision Strike: $3,500 to $4,500
    • Self Revive: $4,000 to $5,000
    • UAV: $4,000 to $6,000
    • Loadout Drop Marker: $10,000 to $15,000
    • Melee: Melee Finisher Damage has been removed. Settle the score with lead.


  • Base Health: Compared to a normal match, all players’ base health is increased from 100 to 250.
  • Health Regeneration: The regen delay timer has been increased from 5 to 7 seconds and regen per second has been decreased from 120 per second to 40. It may be wise for players to reconsider preferred Perks and Equipment.
  • Starting Equipment: Players drop with different equipment.


  • Loot: The item pool for Supply Boxes and items found on the ground have been significantly altered from that seen in standard play. This mode also emphasizes the importance of scavenging to survive – having a knowledge of where to find boxes and being able to complete multiple Contracts are two general Warzone skills that become even more useful in Iron Trials ‘84.
  • Rarity Spawn Rates: Epic and Legendary weapons are now harder to find. Players will have to open a few more boxes than usual to find what they’re looking for.
  • Killstreaks: Drop rates have been reduced. Time to stop spamming UAVs and to start putting those senses to the test.
  • Cash Spawns: Larger piles of cash are rarer. Players will have to stay on top of scavenging for cash if they plan to afford a Loadout.
  • Field Upgrades: No Dead Silence. No Stopping Power Rounds. Period.


  • Sniper Rifles: A single headshot from a Sniper Rifle will only down an enemy if they are within 90 meters. This gives time for those on the receiving end of a long shot to react – the most elite snipers will be able to adjust their strategies accordingly and still dish out lethal damage at long range with precise follow-up shots. [So sniper and shotguns get nerfed but not ARs...]
  • Stun Grenades: Decreased the stun effect duration by 50%.
  • Medical Syringes: Decreased the regeneration rate by 25%. Players will find that this piece of tactical equipment is still quite effective despite this change, especially given altered health regeneration rules.


  • Loadouts: No akimbo. No semi-auto or fully auto Shotguns. Limited selection of Tactical Equipment. It’s down to the bare essentials and the will to survive.
  • Redeployment: If players happen to survive their Gulag match, they’ll redeploy with whatever equipment is leftover from that fight. Be mindful of those resources.

As you can easily see, Iron Trials is a kind of hardcore battle royale, for all those players who find the usual Warzone too simple. Some players have even focused on this mode in particular and have really blossomed here. Check out our Player of the Month Wagnificent.
