Modern Warships Sea Battle Online Guide: Tips and Tricks

1. Always choose the USS Hurricane

When the game starts, players are given the choice to buy one from four tiers 1 ship. Beginners are recommended to choose the USS Hurricane. It is fast and equipped with 2 missile launchers and 2 automatic cannons. Moreover, it is the cheapest tier 1 option. Players are suggested not to buy two tiers 1 ship. Players will also get a tier 2 ship as a daily login reward on their third day. It is recommended players do not spend money on a new ship before getting their free tier 2 ship.

2. Upgrading the Ship

Modern Warships allow players to upgrade their ships and weapons. After heading to the workshop, players will be able to see the stats of the ship and weapons that they can upgrade. It is recommended to upgrade as little as possible to leave upgrade points for a tier 2 or 3 ship.

Ships are upgraded based on a lottery system using upgrade points. The first 3 upgrade slots of the ship’s stats are 100% effective and will upgrade the stats with certainty. However, the chance of upgrading gets reduced to 60% after the first 3 slots. When upgrading ships, players are recommended to not try to upgrade all the slots of a single stat first.

They should upgrade one slot per stat up to three times where the chances of upgrading are still 100%. The same goes for upgrading specific weapons of the ship. Players can also buy upgrade points using in-game dollars, but it is recommended to save money for a better ship.

3. Know all the ways to get in-game money

Players are offered 30 free gold every 1 hour 24 mins by watching an ad. Watching an ad can also get players 20,000 dollars and 2 upgrade points. This can be done by tapping on the number of dollars players have at the top right corner of the screen. These are helpful as they help accelerate the process of buying a better more expensive ship. There are also daily rewards that help.

The more damage players do in battles and the more ships they destroy, the higher the cash reward they get. The number of cash players get for the same damage done to opponent ships increases with higher ship tiers. The higher the ship tier, the easier it is to earn more in-game money.  


There are tournaments held every week where players are rewarded. The user does not need to go out of their way to participate in this tournament. The tournaments just rank players based on their weekly performance. 10 players with the highest damage and 10 players with the most kills are heavily rewarded. But it is quite difficult to get into the top 10 of those categories.

4. Be careful with ship tiers

Three tiers in this game are used to rank ships. Tier 1 is composed of the weakest ships in the game. Using a tier 1 ship means players will battle against opponents who also possess tier 1 ships. The same goes for tiers 2 and 3. However, ship weapons are also ranked in tiers.

If players have a tier 1 ship but are equipped with a tier 2 weapon, they will be matched against opponents with tier 2 ships. Players are suggested to avoid upgrading weapons of lower-tier ships to upper tiers as the battles will be incredibly difficult.

5. Use certain tactics during combat

It is better to have more allies around when engaged in combat. They will help attacking-wise when players can team up and launch missiles against one enemy ship. They can also help defensively by intercepting incoming missiles. Players can also take cover behind mountains and land to avoid enemy attacks. When faced with an opponent’s cannon projectiles, players should ensure the ship’s head is facing the enemy to deal minimum damage. It is also recommended to turn ships when necessary, as this interferes with the ship’s target tracking system.

When the spotted indicator appears on-screen during battle, it notifies players that they are now targeted by enemy ships. It is wise to stay behind and not get spotted too easily at the beginning. Once detected, the ship’s positioning needs to be smart to avoid enemy attacks.

Lastly, players are recommended to buy adequate repair kits and missile countermeasures in the consumables section. If the player’s ship suffers too much damage, tapping on the repair kit icon will repair the ship. Missile countermeasures help reduce the effect of enemy attacks.

Am trying to upgrade my missiles to Harpoon

Some random guy

First go to the menu on the bottom right (it’s called ‘workshop’)
Then go on the ship where you’re weapon you want to upgrade is.
After that you need to click on the weapon you want to upgrade.
Finally you can upgrade the weapon on the right with upgrade points which you can find in the shop
