Mk48.io Help Guide
Mk48.io is a multiplayer naval combat game. You start off a small ship, and consume crates to increase your score (to level up your ship). While a small amount of crates spawn naturally, sinking other ships directly increases your score and spawns many more crates.

There are four ways to move your ship:
- Left click and hold outside your ship's inner ring
- Right click (and optionally hold) outside your ship's inner
ring (this is the recommended way to move)
- Tap and hold (on touch screen) outside your ship's inner ring
- Use the WASD or arrow keys to move, and 'x' key to stop
Once your ship is moving in a direction, it will keep moving, to let you
focus on using your weapons.
If using mouse controls, your ship will turn to point towards your
mouse. You can control the speed of your ship by using your mouse position
between the two rings as a throttle. If your mouse is outside the outer
ring, your ship will increase to maximum speed.
Just like in real life, there are many different types of ships, each
with different advantages.
- Motor-torpedo boats are the type of most level one ships,
generally having multiple torpedoes and possibly guns.
- Corvettes and Destroyers are larger boats that carry more weapons, including
slightly more powerful guns.
- Cruisers are a compromise between destroyers and battleships.
- Battleships are very formidable ships, having extremely
powerful main cannons. They can call in airstrikes to defend against submarines.
- Submarines travel underwater, making them immune to certain
types of weapons, but must surface to fire certain types of weapons and regenerate others at a normal rate.
- Hovercraft can travel on land and water.
- Rams are a special ship type that is designed to ram other
ships. They take very little damage in the process, and inflict extra damage to
the other ship.
- Dredgers have the special ability to modify the land. New land
can be created by clicking in front of them, and old land can be destroyed
by driving over it.
- Minelayers dispense long lasting mines that can help guard a
- Aircraft carriers command a squadron of planes to bomb enemy ships! Planes will follow your mouse cursor.
Once you earn enough points, you are able to upgrade your ship to the
next level. The upgrade choices are shown in top-middle of the screen when an
upgrade is available. Be careful when upgrading, as becoming a larger
ship may lead to crashing into land or a reduction in mobility if the water is too shallow.
Enemies are more likely to detect larger ships. However, some modern ships have
a property known as stealth to help you evade detection.
Here is a full list of ships: Mk48.io Ships
There are multiple different types of weapons available on various
ships. In general, weapons are fired by clicking in the appropriate
direction (although the Space key can also be used).
- Torpedoes are powerful underwater weapons. Some torpedoes
have the ability to track targets automatically, with sonar.
- Missiles are airborne and are faster, but less maneuverable than torpedoes.
- Rockets are like missiles but lack guidance.
- SAMs (surface-to-air missiles) can shoot down aircraft and missiles.
- Gun turrets shoot very fast shells that do moderate
damage. Once fired, a shell is without guidance.
- Depth charges are stationary weapons that can be deployed
against persuing ships or submerged submarines.
- Mines are like depth charges but last much longer and are
- Aircraft fly towards your mouse cursor, and automatically deploy weapons of their own.
- Depositor creates new land. We'll let you figure out if this
can be used as a weapon.
Once fired, all weapons take some time to reload. Each type of weapon
and each turret reload independently. Consuming crates speeds up reloading,
while using weapons underwater slows it down.
All ships have some combination of sensors to identify other ships and obstacles:
- Visual tracks all targets, with a range that depends on conditions.
- Radar tracks targets above water.
- Sonar tracks underwater targets.
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.
To visualize sensor data, look at the dots surrounding the outer circle
around your ship:
- Green dots are friendly.
- Red dots are enemies (visual or radar).
- Blue dots are enemies (sonar).
- Yellow dots are collectibles that increase your health, ammunition, and score.
If a contact is on the border of your sensor range, it will
appear as an arrow. In this case, you know something is there, but not what
