All weapon buffs and nerfs in MW3 & Warzone Season 1 Reloaded

Complete guide to Warzone and MW3 Season 1 Reloaded weapon balance changes with expert loadout advice

Season 1 Reloaded Overview and Meta Impact

The mid-season update for Warzone and Modern Warfare 3 has arrived with comprehensive weapon balancing that reshapes the current meta landscape.

Since the launch of Modern Warfare 3 and its Warzone integration, players have experienced several weapon-balancing adjustments that continually evolve the competitive environment across both multiplayer and battle royale modes.

Previous seasonal updates introduced crucial changes including movement penalties for Riot Shields and adjustments to dominant weapons like the MTZ-556 and Bas-B, which gradually shifted away from meta dominance.

Season 1 Reloaded arrives at the midpoint between Season 1 and Season 2, delivering another significant meta shakeup that requires players to adapt their loadouts and strategies accordingly.

Many players have encountered frustration with the MTZ Interceptor in both Warzone and Modern Warfare 3’s multiplayer, though this marksman rifle surprisingly avoids direct nerfs in this update, with developers promising changes in the “near future.”

This update primarily targets the M13B from Modern Warfare II with max damage reductions, while the problematic MTZ 762 receives substantial damage nerfs across all ranges. Light machine guns face widespread nerfs that should reduce their dominance in Warzone engagements.

Conversely, the Holger 556 and Striker 9 receive meaningful buffs that position them as new meta contenders, particularly in Warzone where their improved performance should increase popularity in coming weeks.

Players must remain aware that specific changes apply exclusively to either Warzone or Multiplayer modes, requiring separate loadout configurations for optimal performance in each game mode.

Assault Rifle Changes and Loadout Recommendations

Assault rifles receive targeted adjustments that rebalance their performance across engagement distances and gameplay scenarios.

    • Decreased maximum damage range from 35.6m to 20.3m (-43%).
    • Decreased medium damage range from 44.5m to 30.5 (-31%).
  • The Holger 556 buff makes it significantly more lethal in close to mid-range engagements, potentially positioning it as a top-tier AR choice. Meanwhile, the M13B nerfs reduce its effectiveness across all damage ranges, making it less dominant in medium-distance fights.

    The MCW receives base damage improvements but faces attachment nerfs that change its optimal build configuration. The MTZ 762 damage reduction across all ranges addresses its previous overpowered performance in both Warzone and multiplayer.

    Pro Tip: With the DG-56 experiencing massive range reductions, consider pairing it with a sniper or marksman rifle to cover longer engagement distances where it now struggles.

    Submachine Gun Updates and Close-Quarters Impact

    SMG adjustments refine close-quarters combat balance with both buffs and nerfs to various popular choices.

  • AMR9 (MWIII)
    • Max Damage increased to 31, up from 28
    • Near-Mid Damage increased to 27, up from 25
    • Min Damage increased to 25, up from 23
  • ISO 9mm (MWII)
    • Max Damage reduced to 21, down from 24
    • Near-Mid Damage reduced to 17, down from 19
    • Mid Damage reduced to 15, down from 16
    • Far-Mid Damage reduced to 12, down from 13
  • Rival-9 (MWIII)
    • Slight reduction in horizontal recoil
    • MTZ Marauder Stock
      • Fire aim stability benefit reduced by 5%
  • Striker 9 (MWIII)
    • Near-Mid Damage increased to 27, up from 25
    • Min Damage increased to 23, up from 20
  • WSP Swarm
    • Increased maximum damage range from 4.6m to 6.6m (+50%).
    • Increased near-medium damage range from 7.9m to 11.7m (+48%).
  • The AMR9 receives substantial damage buffs across all ranges, making it significantly more lethal in close-quarters combat. This positions it as a strong contender for aggressive SMG playstyles.

    Conversely, the ISO 9mm faces comprehensive damage reductions that diminish its effectiveness beyond very close ranges, requiring players to get closer for optimal performance.

    The Striker 9 buffs enhance its mid-range damage profile, making it more versatile for players who engage at varying distances. The WSP Swarm range improvements are particularly notable, extending its effective engagement distance significantly.

    Common Mistake: Avoid building SMGs exclusively for maximum mobility—the range adjustments mean balancing mobility with effective damage ranges is now more important than ever.

    LMG and Sniper Rifle Adjustments

    Heavy weapons receive significant balancing with LMGs facing widespread nerfs and snipers getting targeted adjustments.

  • Bruen MK9 (MWIII)
    • Max Damage reduced to 28, down from 32
    • Min Damage reduced to 26, down from 28
  • DG LSW (MWIII)
    • Max Damage reduced to 29, down from 33
    • Min Damage reduced to 27, down from 29
  • Puleymont AMP (MWIII)
    • Max Damage reduced to 38, down from 40
    • Min Damage reduced to 34, down from 36
  • TAQ Eradicator (MWIII)
    • Max Damage reduced to 28, down from 33
    • Min Damage reduced to 24, down from 25
  • KATT-AMR (MWIII)
    • ZANG-34 Barrel
      • Damage Range Benefits reduced by 9%
      • Velocity Benefit reduced by 8%
  • KV Inhibitor
    • Added medium damage at 129 to 61m.
    • Decreased minimum damage from 129 to 99 (-23%).
    • Decreased maximum damage range from 38.1m to 30.5m (-20%).
    • Decreased near-medium damage from 58.4m to 48.3m (-17%).
  • The widespread LMG nerfs significantly reduce their damage output, addressing community concerns about their dominance in Warzone. These changes should make LMGs more balanced choices rather than automatic top picks.

    Sniper adjustments include both buffs and nerfs, with the KATT-AMR receiving barrel attachment nerfs while the KV Inhibitor gets a new damage profile that changes its effective range characteristics.

    Optimization Tip: With LMGs dealing less damage, focus on building for recoil control and mobility to maintain effectiveness in sustained fire situations while improving handling.

    Attachment and Ammunition Updates

    Attachment and ammunition changes significantly impact weapon building strategies across all weapon categories.

  • SL Razorhawk Laser Light
    • Increased ADS Speed Benefit by 4.5%
    • Increased Sprint to Fire Benefit by 7%
  • FSS OLE-V Laser
    • Reduced the ADS Speed Benefit by 2%
    • Reduced the Sprint to Fire Benefit by 4%
  • .50 Cal Spire Point Rounds
    • Damage Range Benefit increased by 2%
    • Velocity Benefit reduced by 19%
  • XRK Nightfall Suppressor
    • Damage Range Benefit reduced by 5.5%
    • Velocity Benefit reduced by 8%
    • Recoil Benefit reduced by 3%
    • ADS Penalty increased by 7%
    • Sprint to Fire Penalty increased by 3%
  • Laser attachment adjustments change the balance between different laser types, with the SL Razorhawk becoming more appealing for aggressive playstyles while the FSS OLE-V sees reduced benefits.

    Ammunition changes include significant adjustments to .50 Cal Spire Point Rounds, which now offer slightly better damage range but substantially reduced bullet velocity, changing their optimal use cases.

    The XRK Nightfall Suppressor nerfs make it less universally beneficial, requiring players to reconsider their muzzle attachment choices based on specific weapon needs and playstyles.

    Strategic Insight: With attachment changes, avoid automatically using previous meta builds—test new combinations to find optimal setups for the updated weapon statistics.

    Advanced Strategy and Loadout Optimization

    Understanding the strategic implications of Season 1 Reloaded changes is crucial for maintaining competitive performance.

    The comprehensive LMG nerfs fundamentally change the long-range meta in Warzone, making assault rifles and battle rifles more viable choices for sustained damage at distance. This shift rewards accuracy over volume of fire.

    With the Holger 556 and Striker 9 receiving significant buffs, these weapons should be prioritized in your loadout testing. The Holger 556 now competes with other top-tier ARs, while the Striker 9 becomes a strong SMG option for various engagement ranges.

    Attachment changes require rebuilding many existing loadouts from scratch rather than making minor adjustments. The laser and suppressor modifications particularly impact aggressive playstyles that rely on quick aim-down-sights speed.

    Pro Advancement Tip: Create separate loadout sets for Warzone and Multiplayer, as certain weapons perform differently between game modes due to specific balancing adjustments.

    The reduction in LMG effectiveness means players should practice burst firing and accuracy with assault rifles to maintain competitive time-to-kill statistics at longer ranges.

    Experiment with the buffed AMR9 and WSP Swarm in close-quarters scenarios, as their improved statistics may make them superior to previous SMG meta choices in specific situations.
