Levels
There are 7 missions in the main story
These are:
Onslaught
A dropship in an infested space station cannot depart because its door ramps are stuck. The ramps will be repaired in 6 1/2 minutes, but until then, the player(s) must fight off the incoming horde of zombies.
Vaccine
After finding no signs of life other than zombies on Planet Thera, the destruction of the infested planet by an orbital strike satellite is verified in defense of the future to mankind.
However, a zombie outbreak has occurred on planet Aartis, where the remaining members of the human race resides. At the same time, a vaccine has been found in a laboratory on planet Thera by Combot, vital to the survival of humans.
The destruction of Thera cannot be taken back as the attack is already in launch. Thus, SAS soldiers are deployed to the surface of Thera, where they must take a subway to the lab, get the vaccine, and escape to a dropship in less than fifteen minutes, before “Operation Disinfect” commences, the devastation of the planet, destroying the vaccine and the soldiers.
Survivors
The SAS receives communication from locals who are trapped in a heavily populated city on Aartis. The S.A.S are deployed to save the survivors which is 60 people in all. After saving the survivors they will give you S.A.S creds and inside each building is a cash register after shooting each register you will gain more S.A.S creds. after saving all or most of the survivors (even if they all die you can win).
You will need to clear the area of the remaining infected. After killing the rest of the infected, a boss or multiple bosses will emerge from the ground. If the boss is killed, you will gain a strongbox and the mission will end after a twenty second countdown.
Zombie Pods
A digital strain of the zombie virus has taken over Combot and created cyborg zombies. Humans and robotic components are being harvested into egg-like pods. This map is most likely intended for the first encounter with the Zombie Mech
V.I.P.
The VIP is trapped in his house and is in a safe room due to heavy infection in his house. SAS must evacuate the VIP from the house and survive until the evac. chopper comes. (You want to shot him trust me.)
Power Out
A hospital in an infested city has lost power. There is no worry about being infected due to its strong defenses, but the only way to restore power is via four switches through the underground tunnels. The player(s) must repair all four switches.
Last Stand
The last survivors of Aartis are waiting for evacuation in the Market Square. However, the area isn’t secure enough, so players must prevent the zombies from passing with only 25 lives
Multiplayer Game Modes

-Private Match: Allows to play with friends (in this mode you can choose map).

– Nighmare: It costs one Nightmare ticket to play. You have five tickets per day. Zombies are much tougher, and each map is individually redesigned. In addition, Nightmarish zombies exist, which are much larger than normal, and have the Nightmarish buff, which heavily increases their health, size, and damage, as well as 75% resistances to all types of damage. (They also have red labels when moused over.) Even a group of players at lower levels may meet bosses such as Nightmarish Savage Devastators or a swarm of Nightmarish Elite Necrosis, which can often lead to the death of lower leveled levels due to them not having tough enough equipment due to their levels and due to the bosses having all these Nightmarish buffs.
Nightmarish zombies have 10x health and 10x damage, are larger than normal.

Contracts:
*Ammo Recovery: Involves collecting ammunition caches scattered throughout the map and returning them to the spawn location.

Masteries
Masteries are passive upgrades to all grenades, turrets, High Damage (HD) ammo, armor parts and weapon types. Each of the above has 5 levels of masteries. To upgrade to the next level, each category requires you to do different things to gain experience to level up.
For weapons, a particular weapon type to kill zombies will give xp. Note that the xp given is based on the amount of zombies killed, not the quality, meaning killing 2 Worms should give you more xp than killing a Savage Necrosis with the same weapon.
