Engineer/en

Engineer is one of the 5 classes currently playable in Roboquest.

Primary Ability
Engineer's primary ability is Summon-Buddies. Activating Summon-Buddies deploys a friendly drone partner that circles the player. While circling, the drone will target enemies and fire at them every 0.3 seconds, dealing a base 6 damage per shot for a total of 20 damage per second. Without modification, the base number of deployable drones is 2, and the perk has a 16 second cooldown between uses.

The secondary effect of the class melee override directly affects Summon-Buddies cooldown times, reducing the cooldown by 1 second for each scrap collected.

Secondary Ability
Engineer's secondary ability is Scrap Blaster. Scrap Blaster is a projectile-based override with a 3 second cooldown. When used, Scrap Blaster fires a projectile that deals 50 points of explosive damage against the enemies it hit in a 2 meter radius.

Scrap blaster has the secondary effect of generating scrap upon succesfully hitting an enemy. 3 scraps are generated upon a succesful hit. When collected, scrap can directly decrease the cooldown of Summon-Buddies and also synergizes with certain Engineer upgrades.

Passive Ability
Engineer's passive ability is Repair-Buddies. Repair-Buddies changes Engineer's primary ability when the maximum number of drones is deployed; in this situation, Summon-Buddies will now heal all currently deployed drones to maximum health rather than deploying another drone.

Class-Locked Perks
As well as Neutral Perks, each class has their own set of Perks specific to them.

The player can choose a Primary Perk (Which is Class-Locked) at Level 2, 4, 6 and 8 for a total of four Primary Perks.

All Primary Perks unlock two Secondary Perks which can be obtained along with Neutral Perks and Class Locked Perks at Level 3, 5, 7, 9, 10, 11, 12 and 13, and from defeated player character robots, as displayed by question marks on some maps. Depending on your route, you can find up to two defeated player character robots to loot for upgrades per run. One in the Haven map, Oasis and in Ruins. Oasis and Ruins are mutually exclusive in runs.

As shown below, Baby Boom is a Primary Perk. Lucky Powder and Group Discount are Secondary Perks, which need to be unlocked by themselves after Baby Boom is obtained.

Class-Locked Neutral Perks
Perks that in essence function the same as Neutral Perks, but are exclusive to specific classes. In this case it's the Engineer.
