OverviewSpace RigBosco

“	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 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.

Using the [Shout] command 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, nor will enemies target him. He is also invincible and cannot be destroyed by any means unless a second player joins the match.

Functions

Mining

The player can direct Bosco to mine minerals, tunnel through compacted dirt, and dig out Morkite Seeds, though he cannot collect any mined objects. He also can't be used to mine through common/solid rock unless there is a large resource in it, whereas he will stop excavating as soon as the resource is freed. Bosco must be manually ordered to mine deposits with the Laser Pointer; he won't automatically mine out anything by himself. When in mining mode, Bosco will ignore enemies. Equipping the "Mining Expert" modification greatly increases the speed in which Bosco mines.

Gold and Morkite mined by Bosco are not affected by the Pots O' Gold or Dark Morkite beers, as their respective boosts to Gold and Morkite acquisition only apply when using the Pickaxe.

Bosco can be directed to dig out large objects such as Aquarq, Jadiz, Alien Eggs or Mini-M.U.L.E. legs - anything the player can carry, Bosco can carry too. When directed to mine out a large object, he will emit a sound upon uncovering it, then automatically pick it up and start slowly moving towards the player. If Bosco is within 10 meters and has line of sight to the player while holding an object, using the [Shout] command 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] key.

Bosco cannot deposit large resources on his own; the player themselves are required to pick up whatever he is carrying and deposit it into 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, 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 icon will appear above Bosco until he is finished. His spotlight will also turn blue.

Combat

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 creatures such as Glyphid Swarmers, though his low damage is less effective against larger creatures such as Glyphid Praetorians, thus requiring player cooperation to defeat tougher enemies.

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

To direct Bosco to attack a specific enemy, the player must mark it with the Laser Pointer. Bosco will not automatically engage passive or friendly creatures unless directed to by the player. Additionally, Bosco will engage any parts of the Korlok Tyrant-Weed only after the battle is activated.

Bosco's primary weapons can be modified to deal increased damage and/or have a chance to electrocute targets.

When engaging an enemy (either by player command or under his own initiative), Bosco will display a holographic, red-outlined fist icon over his chassis, and his spotlight will turn red.

Rockets

After the "Rockets" modification has been purchased and equipped, Bosco will gain the ability to fire explosive rockets. He can carry up to two at a time (three if the "Extra Rocket" modification is equipped). Rockets are fired by clicking the right mouse button (PC) or pressing the left trigger (Xbox) 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. Rockets can be enhanced in various ways through modifications, being able to shatter Armor, freeze enemies, scare enemies away, recharge faster, and/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 resource chunks, disabling Ommoran Beamers protecting the Ommoran Heartstone (if aimed at the tip) or removing the hazardous effect of Volatile Uranium (if aimed at the center).

Note that Bosco will instantly be rendered immobile if ordered to fire a rocket until he does so, during which he will not be able to attack freely with his primary weapons. He will only fire the rocket if the target is within his line of sight, even if partially, which may cause the rocket to inadvertently hit an obstruction as mentioned above. The player can still move Bosco using the Laser Pointer or call him back to them, though he will still fire the rocket should he move to a position that gives him a clearer view of his target.

Reviving

If the player ends up 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. He will let out an electrical shock before reviving the player, which scares away any surrounding enemies. While reviving the player, Bosco displays a green, holographic heart icon with an upward-facing arrow in it above his chassis.

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.

Being revived by Bosco always restores 40% of the player's maximum health, unlike being revived by another dwarf, which restores different amounts depending on the Hazard Level.

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 whatever you're aiming at for up to 20 seconds or until ordered otherwise. This light can be enhanced with the "Let There Be Light" modification.

While using his spotlight, Bosco displays a holographic yellow lightbulb icon above his chassis. His spotlight also turns yellow.

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 it if it is leaking (it can be cancelled if the player makes a new order or uses the [Shout] command).

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.

Guard

Prior to Season 01: Rival Incursion, Guard was exclusive to Escort Duty missions.

When selecting either the Drilldozer or Hack-C, Bosco will focus on defending it (This can be cancelled if the player makes a new order or uses the [Shout] command). While defending, Bosco will not follow the player and will stay in the vicinity of the Drilldozer or Hack-C until ordered otherwise; this includes after retrieving the Ommoran Heartstone.

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

Vacuum

Exclusive to the Lithophage Outbreak mission mutator or when fighting a Rockpox Corruptor. Bosco is able to vacuum up foam distributed by the LithoFoamer 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 pinging any foamed areas, which will make him prioritize vacuuming up the foam while ignoring any hostile activity.

Note that Bosco cannot apply foam - the application of it is entirely on the player.

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

Modifications

Since 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.

Unlike other modifications, player rank is used instead of character level.

Trivia

• According to Bosco's description, Deep Rock Galactic advises against the personification of robots because of decreased morale in the event of a malfunction.
  • Despite this, Mission Control himself refers to the drone as "Bosco" during the tutorial.
• Using the Salute command will make Bosco return it with a salute of his own and a robotic bark.
• Bosco will react to player-inflicted damage, startling upon being hit. These reactions are purely cosmetic, as he is invincible by all means and cannot be killed even by the player themselves.
• Like the player, Bosco can destroy Spider Webs by running into them. Unlike the player, however, his movement will not be temporarily hindered.
