World of Tanks and Boosteroid are pairing the September Monthly Boost with access to the Tier VIII ASTRON Rex 105 mm, Syrenka-themed customization, account bonuses, and a mission track packed with consumables and XP rewards. Players can choose a one-month or six-month plan and access the game without downloading the client.

The official September Boost announcement uses September 1, 2026 as the current Monthly Boost release date. An active Boosteroid subscription is required for the subscription vehicle and Monthly Boost rewards.

September plan options and subscription benefits

The one-month plan costs €16.89, reduced from €18.99, and is billed every month. The six-month plan costs €89.89, reduced from €99.90, and is billed every six months.

One-month plan includes access to the ASTRON Rex 105 mm while the plan remains active, September Monthly Boost rewards, and first-time subscriber rewards.
Six-month plan includes the same vehicle access and rewards, along with access to the six-month tank lineup.

Rewards arrive immediately and again when the subscription renews, even if a new Monthly Boost begins on the first day of a month. The subscription terms distinguish between full-price and reduced-rate plans. Automatic renewals do not receive a new discounted price, full-price subscribers can manually resubscribe to claim the offer, and reduced-rate subscriptions with auto-renewal keep their discount until canceled.

The ASTRON Rex 105 mm leads the September rewards

The ASTRON Rex 105 mm is built around a five-shell autoloader and remains available while the Boosteroid plan is active. The promotion lists 220/100/75 mm turret armor, 320/320/420 HP average damage, 190/250/53 mm average penetration, and 0.43 m dispersion at 100 m.

The September package also includes the unique commander Jadwiga Wołoszyn, who is inspired by Polish wartime servicewomen. The Syrenka decals draw on Warsaw’s shield-and-sword imagery, giving the vehicle a distinctive local theme rather than another generic battlefield paint job.

Support rewards include a Survival Improvement Suite T1, 100 Experimental Equipment components, and special missions. Six-month subscribers can permanently add one vehicle from the six-month tank lineup to their Garage. If they already own the full lineup, they can choose 6,000 gold instead. To receive the gold and missions, subscribers must link their Boosteroid and World of Tanks accounts and log in within three months of September 1, 2026.

What the September missions reward

The main mission grants ×2 Crew XP after a victory when the player also ranks among the top 10 on their team by XP earned. It is limited to Random Battles in Tier IV through XI vehicles and can be completed up to 10 times per day. Each completion gives 2 Crew XP and 1 September Boost mission token, with the Crew XP applied after the first victory of the day.

Additional rewards unlock as players collect tokens from that mission. The milestone objectives are limited to Random Battles and Tier IV through XI vehicles, and each can be completed once per account.

10 tokens grant 5 Automatic Fire Extinguishers.
20 tokens grant 5 Large First Aid Kits.
30 tokens grant 5 Large Repair Kits.
60 tokens grant 5 Automatic Fire Extinguishers, 5 Large First Aid Kits, 5 Large Repair Kits, 5 28-day reserves providing +300% to Free and Crew XP for 1 hour, 5 28-day reserves providing +100% to Combat XP for 1 hour, and 10 missions for ×5 XP.

First-time subscriber bonuses

Players subscribing to Boosteroid for the first time receive extra items on top of the regular benefits. The package contains the unique commander Jack “Lumberjack” Thompson with Crew XP for one additional 100% perk, 3 Timber Titans decals, 3 Rage Cutter decals, and 1 extra week of the Boosteroid and World of Tanks subscription.
