Developed by R&D to support solo miners with mining, lighting, and fighting. The APD is not meant as a true replacement of a co-worker, but it is known to be a bit more reliable. The APD is popularly referred to as 'Bosco', but Management strongly disapproves of the use of nicknames for equipment. Personification is known to cause depression among workers in the event of malfunctioning equipment.
— Item Description

APD-B317, regularly nicknamed "Bosco" by the dwarves, is an All-Purpose Drone that accompanies the player during solo missions or lone multiplayer missions. Bosco can be directed using the [Shout] command and the Laser Pointer. He can mine minerals, fight off enemies, revive the player should they go down, and helpfully light up locations using his spotlight.

In solo mode, Bosco will remain with the player for the entirety of the mission. He will also appear if the player is alone in a multiplayer match, immediately self-destructing upon the entry of another player. However, if all players but the host leave the game, Bosco will respawn.

Pressing the [Shout] button ([X] by default for PC edition and [LB] for console edition) will make Bosco abandon his current task and come to the player's location. If the player shouts while Bosco is close and carrying a heavy object, he will throw said object towards the player, allowing them to catch it more easily. Otherwise, he will simply drop it.

Bosco cannot be affected by environmental hazards (this includes spider webs, but like the player, Bosco can still destroy them by running into them), nor will enemies target him.


Functions[]

Icon Bosco Mine Mining[]

Bosco can be directed to mine minerals and tunnel through compacted dirt using the Laser Pointer (Click while holding [Left CTRL] by default). He cannot mine through common/solid rock unless it contains a heavy object. Bosco is also not affected by the Pots O' Gold beer, as its boost to gold acquisition only applies when using the pickaxe to mine.

Bosco can be directed to dig out and deliver heavy objects such as Aquarq, Jadiz, Alien Eggs or Mini-M.U.L.E. legs - anything the player can carry, Bosco can carry too (including the Drilldozer's fuel canisters). When directed to mine for a heavy object, Bosco will dig towards said object and emit a sound upon uncovering it, after which he will automatically pick it up and begin slowly moving towards the player. If Bosco is within 10 meters and has line of sight to the player while holding a heavy object, pressing the [Shout] button will direct him to throw it at the player. Otherwise, he will simply drop it. In any case, the player can catch the object with the default [Interact] button ([E] on PC, [X] on console).

Bosco cannot deposit heavy objects on his own; the player themselves are required to pick up whatever he is carrying and deposit it in the M.U.L.E., Mine Head, Mobile Refinery or Drop Pod. He also cannot pick up small ore chunks, brewing ingredients, or secondary objective resources (with the exception of Gunk Seeds, which Bosco can pick up and carry, but only after they've been freed from their sacs).

During Escort Duty missions, Bosco can be directed to mine the tips of Ommoran Beamers off, ceasing their energy beams.

When directed to mine, a holographic blue pickaxe will appear above Bosco until he is finished. His spotlight will also turn blue.


Icon Bosco Fight Combat[]

Bosco HUD

Bosco's HUD.

Close Range Combat[]

Bosco is armed with a pair of submachine gun-type automatic weapons for close-range combat and will automatically use them to engage any threat he encounters, provided the threat is within a certain range of both himself and the player. Bosco can quickly kill off small enemies such as Glyphid Swarmers, though his low damage is less effective against larger threats such as Glyphid Praetorians, thus requiring player cooperation to defeat tougher enemies.

If the player is ensnared by a Cave Leech, Nayaka Trawler or Mactera Grabber, they can have Bosco prioritize rescuing them by calling for him via the [Shout] button.

When engaging an enemy (either by player command or under his own initiative), Bosco will display a hologram of a red-outlined fist over his chassis, and his spotlight will turn red. To direct Bosco to attack a specific enemy, the player can mark it with the Laser Pointer. Bosco will not automatically engage passive or friendly creatures unless directed to by the player. Additionally, Bosco will only engage any parts of the Korlok Tyrant-Weed after the battle is activated.

Rockets[]

After the Rockets modification has been purchased and equipped, Bosco will gain the ability to fire explosive rockets. Rockets are fired by clicking the right mouse button when using a keyboard and mouse or pressing the left trigger on an Xbox One controller while holding the Laser Pointer. Bosco will fire a rocket at the creature or space marked by the player, although terrain obstacles in the direct path between Bosco and the designated target might be hit instead. Rockets will automatically regenerate over time, similarly to Flares. These rockets can be enhanced in various ways through modifications, such as being able to shatter armor, freeze enemies, scare enemies away or cause bigger explosions.

Like any other explosive, rockets can destroy terrain. This gives them a potential, if unconventional, use for destroying terrain in hard-to-reach areas if necessary, such as freeing loose resource chunks, disabling Ommaran Beamers protecting the Ommoran Hearthstone (if aimed at the tip), or removing the hazardous effect of Volatile Uranium (if aimed at the center).


Icon Bosco Revive Reviving[]

If the player is incapacitated, Bosco can rescue them by reviving them. He will do so by flying over to the downed player and defibrillating them with his hands, eventually reviving them. Bosco will let out an electrical shock before reviving the player, which scares away any surrounding enemies. While Bosco will always attempt to revive the player automatically, they can still call him over by using the [Shout] command.

A display on the back of Bosco's chassis indicates how many revive charges he has left. The amount of charges is also displayed on the HUD, and can be increased using modifications. If the player is downed when Bosco is out of charges, the mission will fail.

While reviving the player, Bosco displays a green, holographic heart with an upward-facing arrow in it above his chassis.


Icon Bosco Light Light[]

When aiming at a location that isn't a mineable resource, dirt, or an enemy, using the Laser Pointer will direct Bosco to fly over to the target location and shine his spotlight on the marked area for up to 20 seconds or until ordered otherwise. While using his spotlight, Bosco displays a holographic yellow lightbulb icon above his chassis.


Icon Bosco Repair Repair[]

Exclusive to On-site Refining missions. When selecting the buildable node of a pipeline, Bosco will start constructing the pipeline until it is finished, or he will repair if it is leaking (it can be cancelled if the player makes a new order or presses the [Shout] button).

Note that Bosco cannot lay the pipeline frameworks - solving the pathing puzzle is entirely on the player. Another thing the player must keep in mind when marking pipes is that their marker must be close to the section that requires attention.

While building/repairing, Bosco displays a holographic blue wrench icon above his chassis.


Icon Bosco Guard Guard[]

Prior to Rival Incursion, Guard was exclusive to Escort Duty missions.

When selecting either the Drilldozer or Hack-C, Bosco will focus on defending them (This can be cancelled if the player makes a new order or presses the [Shout] button). This means that Bosco stops following the player and stays in the vicinity of the Drilldozer or Hack-C until ordered otherwise; this includes after retrieving the Heartstone.

While guarding, Bosco displays a holographic red shield icon above his chassis.


Suck[]

Exclusive to missions with the Lithophage Outbreak Mutator, Bosco is able to vacuum up foam distributed by the LithoFoam in a manner akin to the LithoVac. He will do so automatically, but can be easily interrupted by any nearby enemies, in which he will cease vacuuming and engage them. The player can manually order Bosco to clean up by lasermarking any sprayed areas, which will make him prioritize vacuuming up the foam while ignoring any hostile activity.

While vacuuming, Bosco displays a holographic pink vacuum icon above his chassis.

Modifications[]

As of Update 20: Bigger, Better, Bosco, Bosco can be customized using modifications. Modifications can be purchased and equipped using a special terminal in the Space Rig.

Trivia[]

  • According to the item description, Deep Rock Galactic advises against the personification of robots because of decreased morale in the event of a malfunction.
  • Pressing the [Salute] button ([V] by default on PC, [RS] on console) will make Bosco respond with a salute of his own and a robotic bark.
  • Bosco will react to player-inflicted damage, startling upon being hit. However, his reactions are purely cosmetic, as he is invincible by all means and cannot be killed even by the player themselves.
