Mk48.io Help Guide

Basics

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.

Movement

There are four ways to move your ship:

  1. Left click and hold outside your ship's inner ring
  2. Right click (and optionally hold) outside your ship's inner ring (this is the recommended way to move)
  3. Tap and hold (on touch screen) outside your ship's inner ring
  4. 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.

Ships

Just like in real life, there are many different types of ships, each with different advantages.

  1. Motor-torpedo boats are the type of most level one ships, generally having multiple torpedoes and possibly guns.
  2. Corvettes and Destroyers are larger boats that carry more weapons, including slightly more powerful guns.
  3. Cruisers are a compromise between destroyers and battleships.
  4. Battleships are very formidable ships, having extremely powerful main cannons. They can call in airstrikes to defend against submarines.
  5. 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.
  6. Hovercraft can travel on land and water.
  7. 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.
  8. 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.
  9. Minelayers dispense long lasting mines that can help guard a small area.
  10. 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

Weapons

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).

  1. Torpedoes are powerful underwater weapons. Some torpedoes have the ability to track targets automatically, with sonar.
  2. Missiles are airborne and are faster, but less maneuverable than torpedoes.
  3. Rockets are like missiles but lack guidance.
  4. SAMs (surface-to-air missiles) can shoot down aircraft and missiles.
  5. Gun turrets shoot very fast shells that do moderate damage. Once fired, a shell is without guidance.
  6. Depth charges are stationary weapons that can be deployed against persuing ships or submerged submarines.
  7. Mines are like depth charges but last much longer and are more powerful.
  8. Aircraft fly towards your mouse cursor, and automatically deploy weapons of their own.
  9. 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.

Sensors

All ships have some combination of sensors to identify other ships and obstacles:

  1. Visual tracks all targets, with a range that depends on conditions.
  2. Radar tracks targets above water.
  3. 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:

  1. Green dots are friendly.
  2. Red dots are enemies (visual or radar).
  3. Blue dots are enemies (sonar).
  4. 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 it is.

Fleets

You can join up to five other players to form a fleet, using the panel in the top left corner of the screen. Once you have a fleet, other players can request to join it. You can then approve or deny them. Members of a fleet cannot hurt each other with weapons. Importantly, you cannot request to join a fleet until you are close enough to see one of its members, and the fleet has slots remaining.

Beta Program

If you want to try experimental features (at your own risk), enable the Beta program.
