Plagueheart
Plaguehearts are a bonus item introduced with the Season 03: Plaguefall update alongside the Performance Pass. For every 6 Plaguehearts collected 1 
can be claimed at the Season Terminal on the Space Rig, up to a maximum of 15 . When deposited, they will give 300 
(Performance Points) to the team upon mission completion (85 if the mission is failed), also rewarded with 250 
per heart, which is multiplied by the Hazard Bonus.
If a mission is failed, as long as the Plaguehearts were deposited, players will still be able to claim their Scrip progression, as well as some of the experience and credits they grant.
Events
Two types of events can randomly happen during missions: meteor impacts and meteor showers. The game rolls for them independently, so both can happen in the same mission. Each meteor event has a 25% to 33% base chance to happen, adjusted by mission length.[1]
Impacts can open Dreadnought eggs during Elimination, or damage the Drilldozer during Escort Duty.
Meteor Impact
| “ | Heads up, team! A meteor is about to impact your area! Clear the impact zone, immediately! |
| — Mission Control |
The Meteor Impact event can randomly happen once to twice in most Missions. It will kill anything in the impact zone with diminished damage to the dwarves the further of the center and turn the surface around it into hot rock.
After the crash, two Rock Cracker pods can be called down and connected to the meteorite. Once started, the machines will deplete the meteorite's integrity (shown as a bar along the top of the screen) and will need maintenance and protection as they attract waves of creatures. Note that it is slightly more efficient to fix the pods before they fall to 0% "health" than to fix them up from a broken state[2].
Upon completion, 3 to 4 Plaguehearts can be found inside the meteor. Mission Control will give off a response when all Plaguehearts from the meteorite were deposited.
• The objective is to crack the Lithophage meteorite.
Meteor Shower
| “ | Lithophage meteorite fragments are about to impact in your vicinity! Stay alert! |
| — Mission Control |
The Meteor Shower event can randomly happen once to twice in any mission. 4 to 7 fragments will arrive, killing everything in the impact zone and turning the surface around them into hot rock.
After the crash, they can be cracked open with 5 melee hits. One of the fragments is guaranteed to have 1 Plagueheart inside; the rest of them have a 2% chance of having one[3].
• The objective is to crack the Lithophage meteorite fragments.
