Here's how to get the core legally. It does not show the unexpected method.

First, there are the following ways to get the core.

• Nightmare mode
  
• Armory of Faction War
  
• Epic Pack

I will explain each in detail.

You can get cores in Nightmare mode.

The probability is low. This is because there are several barriers as follows.

• Your level is 35 or higher
  
• Team total level is higher than 200 or 396
  
• You can afford to grant "High Roller"
  
• The appearance of Savage Devastator Elite or Savage Necrosis Elite as a boss
  
• Your team has ability to defeat the boss
  
• That boss spawns Nantonium Strongbox
  
• That Nantonium Strongbox contains a core

Cores are obtained from Nantonium Strongboxes from Savage Devastator Elite and Savage Necrosis Elite.
It doesn't matter if the type of special effect given to this boss (Berserk, Extra Fast, Extra Strong, Dark Minion, Nightmarish) has a core or not.
Note that you can't get cores from non-Elite bosses.

The probability of getting a core is as follows.

• Nantonium Strongbox from Savage Regurgitator Elite: 0%
  
• Nantonium Strongbox from Savage Wicker Elite: 0%
  
• Nantonium Strongbox from Savage Zombie mech Elite: 0%
  
• Nantonium Strongbox from Savage Devastator Elite: 5%
  
• Nantonium Strongbox from Savage Necrosis Elite: 15%

The mumber of strongboxes a boss has is fixed.

• Savage Regurgitator Elite: 3
  
• Savage Wicker Elite: 3
  
• Savage Zombie mech Elite: 3
  
• Savage Devastator Elite: 4
  
• Savage Necrosis Elite: 5

In other words, this is the maximum number of nantonium strongboxes that the boss has.
In addition, from a boss you may get multiple cores.
However, a nantonium strongbox contains a maximum of a core.

You need to encounter Savage Devastator Elite (= SDE) or Savage Necrosis Elite (= SNE) to get the core.
The amount of players and team levels are as follows. power out map is special.

• Savage Necrosis Elite
  
  • 4 players: 396+
    

• Savage Necrosis Elite in power out map
  
  • 2 players: 174+
    
  • 3 players: 219~245
    
  • 4 players: 260~285
    

• Savage Devastator Elite in any maps but in power out, it has a chance to spawn a SD instead of SDE
  
  • 2 players: 200
    
  • 3 players: 260+
    
  • 4 players: 300+
    

Depending on the first boss type, you can tell whether the final boss type is SDE or SNE.
In order to have a high chance of encountering SNE, your team level should be 396+.

team level 400, 4 players (100 + 100 + 100 + 100) in vip map
team level 235, 3 players (100 + 100 + 35) in power out map
team level 191, 2 players (100 + 91) in power out map

The amount of cores per ticket is shown below.
If your team level is 396+ with High Roller will be the most efficient way to get cores.

You will have a hard time creating a high level team.
Find multiple high level players.
Or if you don't violate the game's terms of service, create multiple accounts.

When the mission starts, the boss type is determined.
Even if some players leave in the middle of the mission, the boss type will not change.
However, there is an exception for power out map. I started a mission with level 100 and 83 character and got disconnected from the network in the middle. Then the level 100 character encounters savage necrosis elite. On the other hand, a level 83 character encounters savage necrosis (non elite).

When you kill a boss, it determines how many nantonium strongboxes the boss will spawn.
At the same time, it also determines how many cores and keys will be included in these nantonium strongboxes.
If you had the ability to go back a few seconds before killing a boss, you could get cores and keys relatively easily.

The boss is strong. Get ready to defeat the boss.

• Have the following powerful guns.
  
  • 1887 Shockfield (Red/Black)
    
  • Stripper (Red/Black)
    
  • Hornet (Red/Black)
    
  • Hotspot (Red/Black)
    
  • Krakatoa (Faction)
    
  • GG17 (Faction)
    
  • Festungsbrecher (Faction)
    
  • Zerfallen (Prem)
    
  • CM Proton Arc (Prem)
    
• Aim for 99% defense or increase movement speed so that you do not die.
  
• Use Cyro Grenade and Cyro Turret to slow down the movement of the boss.
  
• Go behind the boss and avoid the attack.

Buy "High Roller" due to increase the probability of Nantonium Strongbox.
The rank of all Strongboxes that appear will be increased by +1.
Even if no other player has granted "High Roller", it has little effect on your chances of getting a core. This can be said from my experience.
At least you should buy "High Roller".

You need tickets to challenge Nightmare Mode.
There are 2 types of tickets.

• Daily Tickets
  
• Premium Tickets

Daily tickets are basically given out every 24 hours, up to 5.

• Managed by character
  
• Can have up to 5
  
• Their expiration date is 24 hours
  
• Basically, up to 5 tickets are granted every 24 hours. It does not depend on whether ticket was used or not.
  
• There is a delay

If you want to minimize delay, when exactly 24 hours have passed, you need to take two steps below.

1. Confirm on screen that tickets have been granted
   
2. Do "Force Backup"

Premium Tickets are granted by purchase.
They are common to all characters.
They have no expiration date.

One ticket will be consumed immediately after the mission starts.
If you have both Daily and Premium, Daily Tickets will be consumed first.
If you have the ability to go back in time, you will be able to get your lost tickets back.

You can get the core in Faction War.
The odds of getting a core in Nightmare mode are very low, but compared to that, Faction War will definitely get a core if you take the time.

You need 40,000 Credits and 2,500 Planetary Favors.
Which Planetary Favours you need depends on your situation.

Credits and favors are retained per account.
Items can only be purchased once per player.
Armory items are updated every 14 days.
If you can manipulate time, you will be able to see past and future Armories.

It takes effort and time to get this much credits and favors.

To earn 40,000 credits, you need one of the following:

• eggs: 2,667 (15 credits / egg)
  
• bosses: 1,334 (30 credits / boss)
  
• kills: 400,000 (0.1 credits / kill)
  
• terminals: 4,000 (10 credits / terminal)
  
• generators: 4,000 (10 credits / generator)

Which planets you are most efficient at earning credits for is dependent on your character's abilities.
Here's how to earn credits efficiently.

• If you are fast and have a strong gun, break eggs.
  
• If you are fast but don't have strong guns, play terminals. You can get credits just by touching the terminal. But if you move slowly, the radiation will quickly kill you.
  
• If you are slow and don't have strong guns, play generators. However, you need to stay in one generator for 30 seconds.

Another way is to get your strong friend to earn credits for you.
First, you belong to the same faction as your friend.
Then you have the friend break eggs in private match.
You can earn credits without doing anything.


To earn 2,500 favors, you need to control the target planet for a total of about 10 days (1 favor every 6 minutes).

New wars are very active right after the last war ended. It may be difficult for you to control the planet. For this reason it may be easier to join a new war after 0.5, 1.5 or 2.5 days.

It is also effective to belong to the same faction as a strong friend.

Or you bet on the probability of 1/4.
There are 4 factions in one war.
This means that one faction always controls several planets.
If you belonged to that faction, you could get favors without doing anything.



When the war ends with control of the planet, you will continue to earn favors until you confirm the favors you have gained.
If you are in control of the planet, I recommend that you do not unnecessarily confirm the favors you have gained after the end of the war.
The moment you see the screen shown in the image above, you will stop earning favors.
If you make a mistake, kill app right away.
It may be possible that save data was not updated and that favors earning was not stopped.

For example, as shown in the image above, if you control the planet for about 25 days, you will earn about 6,000 favors.
You don't have to do anything in the meantime.
This is what I call "passive income".

Note: While you continue to earn passive income, you will not be able to get credits and faction items.


Passive income is probably valid for up to 30 days.

What happens after the expiration date?
Note that you get no passive income at all after the 31st day after the war starts.
Note also the difference that it is after the war starts, not after you join a faction.
I emphasize again, you don't even get 1 favor.

In fact, I joined a new faction 1.5 days after a new war started.
And my faction controlled all the planets in about two hours.
On the 30th day after the war started, I got 6600 favors (27.5 days * 240 favors/day).
By the way, on the 31st day, "Faction War Complete" screen was not displayed, and my favors did not increase.
I confirmed this fact in version 2.0.1.

Epic Packs will be sold every Friday Saturday Sunday. It contains the 1x Elite Core.
You can get the core instantly.

The price may be different on Steam and on mobile.
Check both prices and choose the cheaper one.
It's up to you to buy.
