Quality Features of Free Fire Advance Server APK
OB50 updates
The Over‑the‑Air OB50 update for Free Fire is scheduled to launch globally on July 31, 2025, following the conclusion of the OB50 Advance Server testing that ran from July 11–24—this timing is confirmed by multiple sources including the Economic Times and Sportskeeda Ahead of this, the update has already debuted in the Advance Server, giving players early access to new characters like Rin, weapon rebalances, UI enhancements, and the much-anticipated Naruto Chapter 2 crossover.
1: Free New Character (Rin)
Rin
The newest character in Free Fire, Rin, is set to launch on July 30, 2025, and brings a powerful, ninja-style ability to the battlefield. Known as Hayato’s sister, Rin is equipped with an active skill called Kunai Blast, which automatically summons throwing knives (kunai) around her.
Ability
Rin is a passive character with the Gale of Kunai ability: she accumulates up to three kunai every 8–10 seconds (depending on leaks), and each time you deal damage with a gun—whether on an enemy or their Gloo Wall—one kunai automatically launches to strike that target, dealing bonus damage (up to ~12 per kunai, or ~36 total when fully charged), with bonus scaling over longer ranges. The kunai also pierce and shatter Gloo Walls rapidly, making her especially potent against cover-heavy or long-range engagements, turning her into a meta-shaking pick for both sniper and rifle-based builds.
2: New Weapon
Tech Gun 2
In the Free Fire OB50 update, a new weapon called Tech Gun 2 has been introduced, primarily designed for close-range combat with high headshot and body damage. This compact, fast-firing weapon is especially effective in Clash Squad mode, where it shines in early-round skirmishes and aggressive playstyles. Its quick handling and lethal short-range performance make it ideal for rush strategies, particularly when paired with characters like Jota or Skyler.
Test Gun
In the Free Fire OB50 update, a new weapon called Test Gun has been introduced on the Advance Server, offering a powerful sniper-like experience with a unique feature—firing two high-damage shots in quick succession. It also includes an auto-aim or enemy-tracking system, similar to the enhanced VSK94, making it deadly in long-range combat for skilled players. The Test Gun is designed to deliver around 150–200 damage per burst, making it a strong option for precise takedowns.
3: Weapon update
Heal Pistol Tracker
In the Free Fire OB50 update, the Heal Pistol has received a notable auto-tracking enhancement, allowing it to heal its primary target and automatically affect nearby teammates as well. Now when you shoot an ally, it heals not only the main target but also nearby teammates within range, significantly boosting its utility during squad engagements. This improvement transforms the Heal Pistol into a powerful support weapon, especially useful in team fights on both Battle Royale and Clash Squad modes.
Mini UZI Tracker
In the Free Fire OB50 update, the Mini UZI receives a significant auto-tracker buff, making it much stronger in close-range combat: when you shoot one enemy, the weapon automatically targets nearby enemies, helping you land hits even if your aim is slightly off—especially impactful in fast-paced modes like Clash Squad and early BR skirmishes.
MP40: Triple Chip
In Free Fire OB50, the MP40 SMG receives a significant upgrade via the new Triple-Chip upgrade system, allowing players to boost its damage output (from ~25 to ~29 body damage) and greatly increase headshot potential. This makes the MP40 even more lethal in close-quarters combat, especially when upgraded through kill- or chip-based progression. These enhancements, part of Garena’s broader weapon revamp in this update, aim to solidify the MP40 as a top-tier choice for aggressive builds in both Clash Squad and Battle Royale modes.
Trogon: Triple Chip
In the Free Fire OB50 update, the Trogon shotgun’s Grenade Launcher mode has been improved with a 15% boost in damage and a 10% increase in firing range, making it considerably more viable in explosive close-quarters engagements. Additionally, the Trogon now supports a triple‑chip upgrade system that replaces its previous split‑damage behavior with a unified total damage display that marks enemies hit during fire, streamlining feedback and enhancing performance tracking.
VSK 94
In the Free Fire OB50 update, the VSK 94 sniper rifle has been significantly revamped, making it faster and more effective in combat. The reload delay has been completely removed, allowing players to fire up to six bullets continuously, while the fire rate has been increased by about 8%, improving its responsiveness in fights. Additionally, it now features a built-in auto-aim or tracking system that helps lock onto targets more easily, enhancing accuracy during fast-paced encounters. These upgrades make the VSK 94 a deadly hybrid between a sniper and an auto-rifle, ideal for both Clash Squad and Battle Royale modes.
4: New event
CS Peak
In OB50, Free Fire introduces an exclusive new CS Peak mode—an evening-only ranked version of Clash Squad available from 6 PM to 12 AM daily—where teams battle in anonymous 4v4 matches with no player names displayed (just “Teammate 1/2” or “Enemy 1/2”). This mode uses a separate ranking system and offers unique seasonal rewards such as emotes, avatar frames, and banners for attaining specific point thresholds
Naruto Chapter 2
Free Fire’s OB50 update brings an exciting new event, Naruto Chapter 2, launching around July 30, 2025. This event introduces iconic Naruto characters like Itachi Uchiha, Gaara, and possibly Hinata, along with exclusive bundles such as the Itachi, Minato, and Orochimaru outfits. Players can enjoy anime-style voice packs, themed weapon skins, a powerful super emote, and participate in daily “Epic Ninja Trials” to earn rewards. The event arrives alongside the new OB50 features, including a new character named Rin, UI improvements, and gameplay enhancements, making this one of the most anticipated Free Fire collaborations of the year.
Ninja War
In the Free Fire OB50 update’s Naruto Chapter 2: “Ninja War” event, two powerful features—Ninjutsu Scrolls and Akatsuki Keepsakes—add a new layer of strategy to gameplay. Ninjutsu Scrolls, dropped during Clash Squad rounds and special zones, grant unique ninja abilities like Amaterasu flames, Universal Pull, Shikigami bombs, teleportation, and more, allowing players to dominate the battlefield with anime-inspired powers. Meanwhile, Akatsuki Keepsakes are collectible relics tied to chosen Akatsuki factions, unlocking advanced scroll slots and enhancing jutsu effects as you progress through trials. Together, they create a deep and immersive system where players earn exclusive rewards like themed bundles, emotes, and titles while mastering ninja skills in true shinobi style.
5: Game Tasks to Win Diamonds
In the Free Fire Advance Server, players can win free diamonds by completing specific tasks such as reporting bugs, testing new features, and providing feedback through surveys. The main goal is to help developers identify glitches, crashes, or balancing issues before the global release. Players who find unique or critical bugs can earn up to 3,000 diamonds, while top contributors with the most valuable feedback are often rewarded with bonus diamonds. This system encourages active participation and offers a great opportunity to earn in-game rewards without spending money.
