Just a brief overview on the SAS: Zombie Assault 4 Faction War game mode that was introduced in update 1.10, this will continuously be updated as more things are made known.
How to Access
Once you reach level 15 on a character, you will see a new tab appear in the menu titled “Faction Wars” and after selecting it, you will be greeted with two options: joining a friend’s faction via faction code or joining a random war/faction.
Note that joining a faction is tied to your account, so you can switch characters/builds if you want to as long as they are at least level 15 as well.
After you join a faction you will be able to access all that you need. Several planets, an “Armory” tab at the top right, your faction on the bottom left, and the faction “Leaderboard” on the bottom right are shown. You can find your faction code under your faction’s tab so that you can invite others.
Solar System Info
A bit of basic information is provided for each planet in the solar system to give a bit of understanding for each place.
Missions and Credits
Missions can be completed to earn you credits, which is a shared currency among all of the planets and is used to buy each item in the shop. Most of the objectives are pretty straightforward and are done in an apocalypse-type manor, so you basically just need to complete as many objectives as possible before you die or leave the mission (Leaving the mission will result in a failure, so strongboxes will be lost but you still gain credits and contribute towards the objectives).
For the hunt, the boss you have to kill will show up on the map with a blue marker and the boss itself will have a red circle around it.
Upon killing the highlighted boss, a point will be added to the counter on the left, and a new boss will spawn shortly after.
You earn 30 credits per boss objective. Note that killing any boss that isn’t highlighted will not add to your score.
For extermination, zombie nests will spawn randomly around the map one at a time and you will need to destroy them. Just as in hunt, a blue marker will show up on the map pointing towards the nest.
Once the nest is destroyed, a point will be added to your score and a new nest will instantly spawn. You earn 15 credits per nest objective.
Elimination at its core is just an endless or apocalypse mission, with the main objective being to get as many kills as you can.
You earn 1 credit per 10 kills. Note for this one there is no counter and you can only see your score in the mission end screen.
MAPS & MISSION REWARDS
Every map is practically the same, with the only differences being in layout and the background reflecting what planet you are on.
Just about every kind of loot can spawn around the map and the enemies do drop loot every now and then as well, albeit a negligible amount.
Through personal testing, Hunt seems to provide the most chances for strongboxes since you’re directly going for bosses. Extermination is good for farming credits and Elimination provides the most XP. (This is in comparison to each other done around 4mins for each)
Planets and Planetary Favours
There’s not much of a difference between the planets besides what missions they assign and the favours you get for them.
These are automatically generated for everyone in you faction as long as it holds that planet, these can then be used to buy certain items from the Armory.
If you select your faction, you will be able to see an overview of all of the favours your faction own.
In order to gain control of a planet and start earning favours, your faction needs to hit the given milestone before any other faction, so being in the lead doesn’t necessarily mean that you have control of the planet.
The armoury is where you can find all the items on offer which you can buy once you have acquired enough credits.
Keep in mind you will need both types, Credits and the item’s respective Planetary Favour, in order to buy the item you desire. Shown below.
