The Weekly challenge lasts 5 days (starting Wednesdays) with two days off between them. The goal is to collect Stars to get rewards and climb the weekly hall of fame. As of update 1.4 you no longer need to be in a guild to participate in weekly challenges, but you will not get the guild rewards.
Missions
To take part in the challenges you play missions as usual, selected from a special map. One setting is the Town Challenge or Terminus. The Forest Challenge was introduced on Dec 13, 2015.
There are 6 missions each week. The fuel cost for these missions is 4. Missions can be repeated and every time you finish all of the missions with at least one star, you can end that level and pass to the next difficulty. Starting with the Challenge 2.0 system (introduced in early 2017?), there is no delay before you can try a mission again.
If mission has a walker threat countdown, if you want to avoid adding more walkers to countdown then try to have your firearms attacks happen as overwatch attacks.
Ghost Town challenge missions are: Parking Lot, Suburbia, Mainroad, BBQ, Sunday Traffic, and S.W.A.T. (stars are for standard three goals)
| Mission name | mission details |
|---|---|
| BBQ | NO threat countdown. Standard stars. Kill all walkers. Enemies: Tank walkers. |
| Mainroad | Has threat countdown. Standard stars. Open gate and then get to exit. Enemies: Tank + normal walkers (includes zombie piles). {team suggestion: a warrior to quietly deal with first zombie pile) |
| Parking Lot. | Has threat countdown. Standard stars. Gather supplies and then get to exit. Enemies: normal walkers. (And walkers pop up when glowing red doors opened) |
| Suburbia | Has threat countdown! Standard stars. Gather supplies and then get to exit. Enemies: Tank walkers (probably 2) + normal walkers.
|
| S.W.A.T. | Has threat countdown. Standard stars. Kill zombies, open red glowing door and kill zombies that pop out and then get to exit. Enemies: Armored and normal walkers. |
| Sunday Traffic | Has threat countdown! Standard stars. Gather supplies and then get to exit. Enemies: Tank, Armored and normal walkers. |
Stars
The standard challenge stars are: 1 star for passing the mission, an additional star if you don't get into a struggle, and another star if you get no injuries. Sometimes there is an alternate objective/star (example: Complete the mission before the 7th round). (Before the Challenge 2.0 system was introduced you could get additional stars for Daily Quests.)
The stars earned this week count both towards individual and guild challenge goals. You keep your individual stars, but stars earned before you join a guild (or if you change guild during a challenge) will not follow you to the new guild. There is also a "total stars stat" that lists your accumulated challenge stars. The "top players" ranking list will show you as #51 even if you are far below in stars.
Rewards
Apart from the usual mission rewards, there are rewards when you and your guild achieve certain amounts of stars (see table) for the week. Everyone enlisted in the guild (and only those, regardless of when you joined or were banished) when the goal is reached receives the guild rewards for that tier.

Old Challenge 1.0 system
(delete?)
This table shows the gas cost and recommended survivor level based on the amount of stars you have for that particular mission. (Note: In this count the Quest Stars doesn't count.) With the table as a basis it has been suggested that it is a good idea to not reach 3 stars on the first run on each mission. Starting the next run on 2 stars, then 5, 8, 11 (instead of 3, 6, 12, 15) would save 1 gas each run with only a one star initial sacrifice.
| Stars | Gas Cost | Stars | Recommended Level | |
|---|---|---|---|---|
| 0 - 2 | 3 | 0 | 3 | |
| 3 - 8 | 4 | 1 | 4 | |
| 9 - 12 | 5 | 2 - 4 | 5 | |
| 13 - 18 | 6 | 5 - 7 | 6 | |
| 19 - 24 | 7 | 8 - 10 | 7 | |
| 25 - 30 | 8 | 11 - 14 | 8 | |
| 31 - 36 | 9 | 15 - 17 | 9 | |
