Vault coins are a special currency in Modern Warships used to unlock past battle pass rewards, which players can obtain by purchasing specific battle passes or through events. So how do you use vault coins in Modern Warships? They are mainly used to exchange for limited equipment, ships, and other resources from previous seasons, but there are certain restrictions on their usage. In the following, I will provide an introduction on how to use vault coins.

Vault coins are primarily used to unlock past battle pass rewards, including limited ships, weapon skins, and rare equipment. If a player missed out on items like the "Storm Fighter" or "096 Nuclear Submarine" in a particular season, they can use these coins to reactivate that season's battle pass and unlock the rewards level by level. When exchanging, it's important to note: each battle pass must be purchased separately to unlock access, and coins are only used to redeem specific reward tiers within an already unlocked battle pass.

Currently, the ways to obtain vault coins are relatively limited. Firstly, by purchasing a VIP pass, as some high-tier battle passes (such as purple or gold passes) include vault coin rewards, requiring direct spending. 2. Limited-time event exchanges: Some holiday or version update events offer coin redemption codes, but the quantity is small and highly random. 3. Additional rewards from battle pass missions: There is a very low probability of obtaining them through "special chests" during battle pass upgrades, but this is not a stable source.

For redemption, one aspect is binding with the VIP pass: coins can only be used after purchasing the corresponding battle pass, for example, November battle pass coins cannot be used to redeem October battle pass rewards. Some battle pass rewards may be weakened with version updates (such as torpedo damage adjustments), so it's necessary to pay attention to version balance before making a purchase. Given the high cost of obtaining coins and the fact that some rewards can be bought at a lower price on the market, non-collectors are advised to invest cautiously.

Vault coins provide players with the opportunity to make up for regrets from past seasons, but they are indeed quite expensive. For light spenders, it's recommended to prioritize obtaining resources through free battle passes and market transactions. For big spenders, they can target high-value limited content for redemption.
