Season 6: White Nights launched on June 30 and it is the largest content drop Arena Breakout: Infinite has had. As the first season after the game's first anniversary, MoreFun Studios is treating it as the start of a new chapter it calls ABI 2.0, and the scope backs that up: a dedicated PvE mode, a casual co-op mode, a progression system, two new weapons and a rebalance that reshapes the meta.
Here is what actually changed and what it means for how you play.
Hostile Sector: the PvE mode
The biggest addition is Hostile Sector, a PvE-focused mode that finally gives the game a place to fight without the constant threat of another squad.
- Maps: PvE on Farm and Northridge (solo or multi-team), PvPvE on TV Station
- Extreme weather: night, fog, storm and blizzard conditions
- Enhanced enemies: new Special Forces archetypes, specifically breachers, snipers, grenadiers and fumigators, plus stronger standard AI and Boss Events
The weather is not just atmosphere. Fog and blizzard conditions gut your effective sightlines, which flips the usual value of long-range optics and rewards close-quarters loadouts you would normally leave in storage. Fumigators in particular punish players who hold a single position, so the mode plays much more mobile than a standard raid.
Supply Drops: co-op without the loss
Supply Drops is the casual counterpart. Four teams compete on the Air Port map, no custom loadout is required, and respawns are unlimited. You loot resources and deposit them into Personal or Team Supply Crates, and the haul is split among team members.
Because there is nothing to lose, this is the mode to send new players into first. It teaches map geography and fight positioning without the gear anxiety that makes new raiders hoard equipment they never use.
The Mastery system
Season 6 adds a Mastery progression layer that enhances basic character skills. MoreFun has been explicit that these are not superpowers, they are modest improvements to what your operator already does.
The design detail that matters is that Mastery Points are easy to obtain and respecs are flexible. You are not locked into a build, so treat Mastery as something you retune per mode rather than a permanent commitment. What works in a Hostile Sector blizzard is not what works in a standard PvP raid.
New weapons, ammo and tactical items
Two weapons joined the roster:
- Banshee submachine gun
- T88 marksman rifle
Alongside them, two new tactical items, the Experimental Shock Grenade and the Y40 Experimental Ultra-Strength Treatment, and three new ammo types: .45 APWC, 12x70 Dragon's Breath and 5.56x45 M855A2.
The ammo additions are the ones to pay attention to. In Arena Breakout: Infinite your ammunition matters far more than your weapon, since penetration decides whether your shots do anything at all against armour. You can compare every round's damage, penetration and armour class in the ammunition database, and check what each new throwable does in the throwables section.
The rebalance: what got hit
Season 6 came with meaningful nerfs and rule changes rather than pure additions:
- Weapon rebalancing, including a notable 191 series nerf
- Red ammo can no longer be placed in secure cases
- No extra accessories in chest rigs or backpacks when entering a raid
The secure case change is the one that will alter behaviour most. Red ammo was a low-risk way to bank the best rounds in the game, and removing that means top-tier ammunition now carries real risk every time you bring it in. Expect more players running purple ammo as a deliberate economic choice rather than a compromise. The weapon database lists each gun's compatible calibers if you are rebuilding around the change.
Control and handling changes
A cluster of smaller fixes that collectively make the game feel noticeably better:
- FOV no longer shifts when entering ADS
- Reduced FOV difference when leaning left or right
- Improved weapon holding dynamics while aiming, with reduced sway penalties while moving
- Inspecting weapons no longer slows movement speed
- Vaulting can now be performed mid-air, which cuts down on getting stuck on geometry
The mid-air vaulting fix deserves more attention than it got. Getting hung on waist-high geometry during a repositioning move was a genuine cause of deaths, not just an annoyance.
Events and personalisation
Solo Op Knife Fight returns as melee-only combat at the TV Station, and the Warlord Tournament updated its ranking rules, capping total stars earned from Team Rank and Personal Eliminations Rank at 3.
On the cosmetic side, you can now toggle the display of Actual Equipment and change your character's gloves.
Where to start
If you are coming back for Season 6, the efficient path is Supply Drops to reacquaint yourself with the maps, then Hostile Sector on Farm to learn the new enemy archetypes in a lower-pressure environment, then back into standard raids once you have rebuilt your ammo economy around the secure case change.
