Mk48.io is a multiplayer naval combat game. You start off a small ship and consume crates to increase your score, which levels up your ship. You have to go find the crates: they float in the water, and you collect one by sailing into it. While a small amount of crates spawn naturally, sinking other ships directly increases your score and spawns many more collectibles. Watch out for torpedoes!
To play, pick a game mode on the splash screen. If applicable and desired, adjust the region, server, or starting ship. Then press Play.
There are 3 ways to play with friends:
There are four ways to move your ship:
Once your ship is moving in a direction it will keep moving, so you can focus on using your weapons.
With mouse controls, your ship turns to point toward your cursor, and you control its speed by varying the distance between the cursor and your ship — near the ship is slow, far away is full speed. A quick left click fires rather than steering, so only a *held* button changes course. Level 1 ships cannot reverse with mouse controls.
All keys can be rebound in the Controls settings.
Pinch to zoom out for a better view on a touch screen; with a mouse, scroll.
Just like in real life there are many different types of ships, each with different advantages:
See the ship reference for the full roster and its statistics — length, draft, speed, health, stealth, torpedo resistance, maximum depth, and the range, damage, lifespan, and reload of each weapon.
Note that certain values are approximate and may be affected by other factors. For example, weapon damage depends on hit location.
Once you earn enough points you can pick an upgrade from the top-middle of the screen. Be careful when upgrading: becoming a larger ship may lead to crashing into land, or to reduced mobility if the water is too shallow.
Enemies are more likely to detect larger ships. However, a few ships have a property known as stealth to help you evade detection.
Not every ship is available everywhere — a few are restricted to certain areas, and some are NPC only.
There are multiple different types of weapons available on various ships. In general, weapons are fired by clicking in the appropriate direction, although Space or E can also be used. Select an armament group with 1-6, or cycle with Tab.
Once fired, all weapons take some time to reload. Each type of weapon and each turret reloads independently. Consuming crates speeds up reloading.
All ships have some combination of sensors to identify other ships and obstacles:
There are two modes for sensors, active and passive. Passive mode listens for emissions (e.g. sound in the case of sonar) from other entities. Active mode emits a signal and resolves contacts based on the signals that bounce back. In general, active mode allows you to see more, but has the potential to give away your position. Toggle between the modes with Z.
A contact your sensors cannot identify — one at the edge of your range, say — is drawn as a plain marker pointed along its heading. You know something is there, and which way it is going, but not what it is.
You can join other players to form a fleet, using the panel in the top left corner of the screen. As the creator of a fleet, you can accept or deny those who request to join it. Members of a fleet cannot hurt each other with weapons.
Fleets have a limited capacity that grows with the number of players online, from 4 members up to 8 on a busy server. In 2 Fleets the two standing fleets have no such limit.
In 2 Fleets you may defect to the opposing fleet by sailing into its half of the map and pressing the defect button. Defecting is blocked while you are damaged, reloading, near another ship, or being tracked by an enemy weapon — repair fully, wait for your weapons to reload, shake off enemy weapons, and move away from other ships first.
The map runs from the tropics in the far south to the Arctic in the far north.
Experienced players may attempt to explore the Arctic, located far north. It is important to understand that the Arctic has three separate types of terrain: snow, ice sheet, and cracked ice sheet. Snow, which appears white and smooth, will damage any ship upon contact. The two types of ice sheet will slow and damage most ships, the difference being that non-icebreakers cannot destroy non-cracked ice sheet. Submarines can travel beneath both types of ice sheet.
Some ships are tied to a region: icebreakers keep to the Arctic, while dredgers are kept out of it.
The sea itself will sink you if you are careless:
As you play you earn ranks: Ensign, Lieutenant, Commander, Captain, Colonel, and Admiral.
