What are Infected Fiends in State of Survival?

Stronger infected that spawn on the world map, in six levels. They are killed with rallies rather than solo marches.

What are Kill Rewards?

Extra rewards given to all rally members after defeating a Fiend of level 4 or higher. They can be obtained three times per day.

When do Kill Rewards reset?

At 00:00 UTC daily. Check that against your own timezone, since the rollover can fall mid-session.

Do I need joiners to rally a Fiend?

Not necessarily. If nobody from your alliance joins, Final Hope reinforcements arrive in the last moments before the rally launches.

Which Fiend level should I target?

Level 4 or above, always. Lower levels cost the same stamina and pay no Kill Rewards.

Is it worth joining Fiend rallies with a small account?

Yes, and disproportionately. Kill Rewards go to every member regardless of contribution size, so a developing account collects at the same rate as a large one.

Are Infected Fiends the same as Infected Horde?

No. Fiends are always-available world map targets. Infected Horde is a scheduled wave-defence event.
