Easiest Achievements To Start With

Achievement typeHow to unlock faster
First large-zed killsPlay Normal or Hard and focus Scrake/Fleshpound assists
First boss killsJoin standard Survival games and finish any boss
Door weldingWeld a door to 100 percent during trader time or a calm wave
HealingUse the syringe or Medic weapons on teammates
First map clearsStart with Normal difficulty on familiar maps
Early perk levelsPick one perk and keep playing it until level 5

The fastest early route is simple: play Survival on Normal or Hard, heal teammates, weld doors when safe, and stay on one perk long enough to unlock the first level milestones.

Harder Achievement Groups

GroupWhy it is harderPractical advice
Hell on Earth map clearsRequires strong perk levels and team disciplineUse coordinated teams and known hold spots
CollectiblesObjects are hidden across mapsUse a checklist and clear the map before ending waves
Rare boss tasksRequire timing or specific boss behaviorLower difficulty helps, but team coordination matters
Full perk progressLong grind across many perksRotate perks after reaching key milestones
Seasonal mapsSome are tied to specific map themesTrack which map family each achievement belongs to

Perk Progression Strategy

Do not chase every perk at once. Level one reliable perk first so you have a high-level fallback for difficult map achievements.

GoalSuggested approach
First level milestonesChoose your favorite perk and stay with it
Team utilityLevel Field Medic or Support if you play with friends
Solo comfortPick a perk with strong self-defense and clear speed
Completionist routeWork one perk to a milestone, then rotate
Hard clearsReturn on your strongest perk instead of forcing a low-level one

Map Completion Route

  1. Clear maps on Normal to learn layouts.
  2. Repeat the same maps on Hard with better perk levels.
  3. Save Suicidal and Hell on Earth for a stable team.
  4. Track collectibles while doing lower-difficulty clears.
  5. Do not mix achievement farming with serious HoE attempts unless the team agrees.
