Geyser mode

takes place on a volcano island with a lot of geysers and a crater lake in the middle, side vent flank craters on the side of the volcano. there's smaller, acid lakes that damage you (5 damage per second) around the crater lake, but not blocking it totally. this mode is also in the event rotation, the 7th mode. the map's a bit smaller than the 50v50 map, but not a lot.

all guns, ammo, harming grenades and melee weapons are rare. smoke grenades are slightly more common. hooks, wood axes, fire axes, sledgehammers, stone hammers, spades, crowbars, ice picks can be dropped from crates, but are rare. separators and bonesaws are common. ghillie suits are as rare as level 2 pack in normal.

no red zone - game ends every 10 minutes, ending with the volcano in the center erupting until everyone's killed. this would vaporize the lake.

XP artifacts are as common as bandage and soda

pills, med kits, bandage and soda are 10x more common - applies for everything from ground loot to golden airdrop loot

level 4 (including the backpack) and 3 equipment are uncommon around the map, but can spawn on ground and in crates

everyone has the hunted, so you can see everyone's location

no buildings, except for shacks, outhouses, containers

pans are as common as med kits in normal mode

no trees, bushes, berry bushes, barrels, silos, hedgehogs, lilypads. except for the perimeter of the volcano island, and another, smaller island full of stone, barrel, and tree caches. on the island, there's also golden soviet crates, which are soviet crates but drop better items, and diamond parma crates, which are parma crates but drop better stuff, this hints, that this island was part of the war between PARMA and the USSR. in the center of the island, there's a big flare crate (not to be confused with the one in woods mode). if you break it, you get 4 flares and 4 flare ammo. this island also has a crater, but it's not active.

medical perks (combat medic, revivify, mass medicate, windwalk) are as common as M9s and OT-38s in normal mode

geysers: heal you/boost, they can either:

heal you 10%, 15%, 20%, 25%, 30%, 40%, 45%, 50%, 60%, 70%, 75%, 80%, 90%, 100% (the morre it heals you, the more rare it is)

or

boost you, which is fill up your boost bar, 10%, 15%, 20%, 25%, 30%, 40%, 45%, 50%, 60%, 70%, 75%, 80%, 90%, 100% (the morre it boosts you, the more rare it is, same as above)

and

geysers that revive you

there's also a volcano crate in the middle which drops exclusive perks

perks:

unpacker: all obstacle damage is 5x more

self repair: you heal to full health 15 seconds after you take even the slightest amount of damage, this is very OP

portable geyser: same as self repair, but for boost (refills boost bar if it reaches 50%). also, your helmet has a little volcano on it (it's more cool if it's a volcano). it would always emit a smoke cloud, with the same effect as the smoke grenade, but less range

auto revive: if you get knocked out, you get revived instantly. this is better than revivify.

speedy loader: all reloading are 2x faster

fast loader: all speed reduced by reload is taken away

caldera: volcano crate perk, people near you (in your 1x scope FOV) walk at 70% of normal speed

cinder cone: all bullets shot by you are 10x the original speed

dragon (role): you get a M134/AWM-S, cast ironskin, takedown, stone hammer, 8 MIRVs, 4x scope, every consumable to the brim of your lvl 3 backpack, infinite ammo, upon promotion. the first gun slot is a flamethrower.
