SAS: Zombie Assault 4 (Flash), also referred to as SAS 4 or ZA4, is the original version of the fourth game in the main SAS: Zombie Assault series. It is the sequel to. SAS 4 began open beta on May 11th, 2014, as announced on the Ninja Kiwi forums by an administrator. .

It has been superseded by SAS: Zombie Assault 4(Cross-Platform) commonly referred to as mobile port of SAS 4. Flash as a technology has been discontinued by adobe, and no further development of flash games by Ninja Kiwi will occur as of 2017.

On a blog published on May 16th, 2014, it was announced that a mobile port of SAS 4 was "a long way into development." Regardless, it was later released in October that year.

Pre-release
Zombie Assault 4 was said to be in early development on a Ninja Kiwi blog on January 22nd, 2014. On a blog published on February 28th, an image of the title screen was made available on Imgur, and put on the blog as a 'hidden' link in the response to the question "Is it possible to share some spoilers for new games?".

Another 'hidden' link to a file on Imgur was included in a blog from March 14th, 2014 in response to a question. This time it was a GIF animation of a few seconds of gameplay - a soldier shooting zombies inside a building, while a timer above counts down. It was seen here that turrets, Premium Ammo, and Grenades and Cryo Grenades would be included.

Gameplay
There are three character classes, each with their own unique skills, 75 weapons with 11 unique augmentations, and 57 body armor pieces with 13 different augmentations. All of the armor pieces and weapons are obtained by strongboxes, which are obtained in several ways. There are total of 12 industries that make weapons and armors. Like with Zombie Assault 3, 4-player co-op multiplayer is included. Chat is included in multiplayer. Also, the players can now play multiplayer without having a full-room. Passive upgrades on weapons, armor, grenades, and turrets (called Masteries) were also introduced to the game by the 8th October patch.

The style of gameplay in Zombie Assault 4 differs from 3: rather than the player defending themselves from waves of zombies on a map, the player progress through maps in level-like fashion with objectives to complete.

Character
In SAS: Zombie Assault 4, you are allowed to have two different character slots open, until one of them reaches level 20, unlocking a third slot. Another slot is unlocked when a character reaches level 60. You also have the option to purchase a fifth and sixth slot for 20 NK Coins.

When creating a character, you can choose between the Assault, Medic, and Heavy classes, from left to right. The description for each is as followed:
 * "Assault troops are used by the Federation when speed, surprise, and violence of action are required above all else"


 * "In addition to their deadly SAS training, a Medic employs a number of fast and efficient means of human tissue repair"

Each class has 7 special skills unique to its kind. Ultimate abilities can only be trained after level 20. The Assault's special skill is "Assault Team", which calls in a team of several soldiers to drop in the game and fight for several seconds. The Medic's special skill is "Zombie Antidote" which does large damage to zombies in a large area. The Heavy's special skill is "Aerial Bombardment" which is an air strike in a selected area.
 * "Heavy Gunners' special skill make them ideal for delivering overwhelming force to enemy positions".

When first creating a character, you receive 2000 SAS cash to purchase gun augments, turrets, or grenades. You receive a strongbox each time you level up, giving you either new gear or a new weapon. You also receive more cash. Another difference is that players now collide with zombies and can't run through them. This may sound benign, but actually fundamentally changes the game, making the actual zombie fighting more skill-based, and also makes the game more tactical.

Trivia

 * SAS: Zombie Assault 4 is the first SAS game out of the series to have a space setting.
 * The game is also the first in the series to have actual characters, minus the one scientist found in the Zombie Assault 3 Bamboo Thicket map, though the scientist didn't have a name.
 * It is also only version to have all weapons unique.
 * The game is also the first to have human antagonists, added in an update to the game.
 * In Zombie Assault 4, the first mission has you defend the ramps with blast doors being like barricades (that you cannot repair, however) from the first three games, and the eighth mission features an area at the beginning that must be defended that has fixable barricades. The seventh mission is similar to a tower defense like.
 * Unlike previous games, where you buy guns in stores along with armor, you actually have to find guns and armor in strongboxes found in secret areas or by killing a certain kind of bosses or, less commonly, regular zombies,
 * Missions in Zombie Assault 4 are unlocked like the regions in the mobile version of Zombie Assault 3: the player has to be a certain rank or higher before they can start them.
 * Once at Rank 20, players of the Assault class unlock a skill that calls forth A.I. buddies, similar to the Buddy of the mobile version of Zombie Assault 3 but armed well and disappears after a certain amount of time.
 * The Assault class SAS is shown holding a RIA 20 Striker, while the Heavy Class is holding a HVM 008 and a Medic Class SAS is holding a CM Gigavolt. The Heavy Class would be shown holding a HIKS R40 in closed beta, but was changed since the gun has never been added to the game, getting replaced with the HVM 008.
 * Despite being in the year 3104, the SAS still has some weapons that resemble modern-day weapons.
 * Unlike previous games in the series, Zombie Assault 4 has its own unique ranks and insignia.
 * There are 7 unique skills for each class.
 * The highest movement speed buff is 107%. With a Dragonfly Helmet at 4%, the /Black Rubicon Power Assist at 18%, the Shotlite Hummingbird G1 at 1%, the Dragonfly Legs at 3% plus 10% from 12* Machine Assisted and 3% from Pants Mastery, and finally /Black Titan MEM Sprint at 12%, plus 10% from 12* Machine Assisted and 3% from Boots Mastery. This adds up to a 64% movement speed buff, which becomes 103% with 25 Skill Points in Fast Movement (which provides 39%). Additionally, collecting all Boots will give a 2% bonus. To top it off, the level 1 pistol Mastery provides a 2% movement buff.
 * The title screen depicts an Assault Class SAS wielding RIA 20 Striker struggling against a shambler.
 * However, Assaults can get to +53.82% faster for 11.0 seconds, with the Adrenaline skill. This equals an insane 215.331% movement speed buff for 11 seconds.
 * On the other hand, the highest movement penalty is -167%. A full /Black Hardplate set would result in a -72% movement penalty, and the HIKS M1000, as the heaviest weapon in the game, would subtract another 95%. If one doesn't have a HIKS M1000, the next best weapon is the Zerfallen at -80%.
 * Some of SAS4 sounds are actually recycled from SAS3. One of the most easy-to-recorgnize is the firing sound of HVM 001, which is almost the same as Glock 17 from SAS 3.
 * In multiplayer in any mode, if you die and wait through the revival of your character you will have a grace period of complete immunity to everything as well as being able to phase through zombies (no collision) for 5 seconds.
