How the game works
Summary
You start as a lone infected player and build power by spreading your infection. Every helper you gain fights alongside you, so a bigger army means faster progress. Effects can be combined to make your army even stronger.
- Infection touch NPCs or players to convert them into helpers who fight for you
- Battle fight other players to earn points
- Effects collect and combine them to enhance your army's strength
- Quest complete the scientist's quest to earn the Quest Completo badge
- Leaderboard reach the worldwide top 100 in any leaderboard to earn the Champion badge
Getting started
Step
When you first load in, you have no helpers and no points. The quickest way to change that is to go after NPCs before you engage real players. Once you have a few helpers, you can start earning eliminations much more efficiently.
- Find an NPC approach it and infect it to create your first helper
- Repeat infections keep infecting NPCs to build a small army before picking fights
- Pick a fight with helpers backing you up, challenge other players to earn points
- Grab effects apply effects to your army and try different combinations to boost their strength
- Take the quest find the scientist and finish their quest to unlock Quest Completo
Infecting players vs. infecting NPCs
Table
NPCs and other players both become helpers when infected. Knowing the difference helps you decide who to target at each stage of a match.
| NPCs | safer to infect early, ideal for building your first group of helpers |
| Players | harder to infect, but they become stronger helpers once converted |
| Effects | work on both NPC and player helpers, so keep combining them regardless of your army's makeup |
Elimination badges and how to reach them
Table
Each badge requires a cumulative elimination total — these do not reset between sessions, so every match counts toward your next milestone.
| Badge | Eliminations required |
|---|---|
| Kinda Brutal | 1 |
| Normally Brutal | 10 |
| Very Brutal | 100 |
| Extremely Brutal | 1,000 |
