Our final naval event of the year is dedicated to the coastal guards who patrolled the USSR’s maritime borders on ships and boats. Participate in naval battles to earn themed decals, the Soviet border guard flag, and the AK-225 patrol gunboat!

The AK-225 was developed as a patrol gunboat for the USSR’s allies. This small, fast vessel with a tracking radar features an impressive armament loadout consisting of an automatic 57 mm cannon with armor-piercing and high-explosive fragmentation rounds. It’s mounted on the bow, and the famous six-barrel AK-630 mount is mounted on the stern. The AK-225 can dispatch other boats and low-flying aircraft with ease!

Among the rewards in the event is also this chest. When opened, there is a chance to receive one of the following items:

• 50,000 - 100,000 Silver Lions
• Silver Lion and Research boosters
• Random Wagers and Orders
• Universal Backups (1 - 3)
• A random obtainable camouflage for a vehicle you own
• 1 day of Premium Account

How to get all rewards

Each stage can be completed for 35,000 mission points, every new stage you finish will give you a new reward.

You’re able to earn mission points in Naval Battles at Rank III or above in Arcade and Realistic Battles. The number of mission points to complete a stage depends on the game mode and the maximum Rank of the vehicle that you use in battle. There’s a multiplier for earning mission points, which is shown in the task description in-game.

You can also earn mission points by using event vehicles that are Rank I and II. Event vehicles that can be used have the name of the event that they were obtainable in on their stat card.

Rewards are given when you complete a specific number of stages

• For 1 Stage: trophy with a random reward
• For 2 Stages: one of the reward decals
• For 3 Stages: trophy with a random reward
• For 4 Stages: one of the reward decals
• For 5 Stages: trophy with a random reward
• For 6 Stages: “Flag of the naval units of the Border Troops of the USSR” ship flag
• For 7 Stages: non-tradable coupon for the AK-225

Discounts for purchasing stages using Golden Eagles

Incomplete stages can be purchased for Golden Eagles, but if you’re significantly close to completing a stage, its price will be significantly reduced.

Let’s say you have earned 85% of the required mission points to complete a stage, then the price of purchasing this stage will be halved. If you’re near the finish line for a stage and are at 95% progress, then the price will be reduced by five times. For example, if you’ve scored 30,000 mission points, then the price for unlocking this stage will be 499 Golden Eagles. If you’ve scored 33,500 mission points, then you’ll only need 199 Golden Eagles. Remember to keep this in mind if you run out of time for a stage!

The Upgrade for a coupon

When you complete 7 stages, you’ll receive a non-tradable coupon for AK-225, where using it will immediately activate the vehicle on your account. If you don’t want the vehicle and would like to sell the coupon on the Market, you’ll need the “Upgrade for coupon” item.

After receiving the “Upgrade for coupon” item, you can convert the non-tradable coupon into a tradable one and sell it on the Market. The tradable coupon can be sold after 6 days from the moment it’s created.

The “Upgrade for coupon” item is valid until December 22nd (11:00 GMT). Until this time, you can use it or exchange it for War Bonds. Afterwards, it’ll disappear from your inventory.

Tracking your progress

You can track the progress of the stages and the “Upgrade for coupon” item by clicking on your Nickname > Achievements > Sea Defender. If you don’t manage to complete a stage on time or would like to purchase a stage, you’ll be able to do so until December 22nd from the Achievements window, you can purchase each stage with Golden Eagles which will give you the corresponding rewards.
