SAS: Zombie Assault 4 – Action Game Review
SAS: Zombie Assault 4 is a Action/Roleplaying/Entertainment game from Ninja Kiwi Limited, first launched in 23rd October 2014.
It’s rated 12+ and currently has 20,764+ ratings on the App Store.
What Makes SAS: Zombie Assault 4 Stand Out
Purge the undead! Awesome upgradeable guns and armor, unique class skills, and 4 player co-op! Play the most intense zombie shooter on mobile, from the makers of Bloons TD 5.
A virus outbreak on a distant trans-federation planet unleashes horrors from humanity's past. A powerful, rapidly growing zombie horde threatens the very existence of humankind, and the only ones capable of fighting back are the highly skilled, highly weaponized special forces of the S A S. Choose from 3 unique character classes, maximize the fully customizable skill tree, and select from hundreds of weapons and armor pieces to build the ultimate zombie killing hero. Play dynamic, challenging levels in single player or 4 player cooperative multiplayer and give our ravaged civilization its last best hope for survival.
INTENSE ACTION
Zombies swarm the screen, exploding into bits under your hail of bullets. Each of the 17 unique zombie types have special attacks and behavior, and they can evolve – manifesting terrifying new powers as you progress through the game. And just when you think you've beat them all, savage boss zombies hunt you down, puking out acid worms or storming after you in rage mode. Learn their strengths and weaknesses as you lead the action across 7 story-driven maps with varying victory conditions.
UNBEATABLE 4 PLAYER CO-OP
Quickmatch with up to 3 other players of similar level and use the custom skills and weapons chosen by all players to form an effective fire team. Coordinate auto-turret placements, high level room-clearing powers like Assault Team, Aerial Bombardment, and Zombie Antidote, and move physics objects to create temporary cover while you paint the room red.
HEAPS OF EPIC LOOT
Over 160 incredible guns and armor pieces are locked up tight inside increasingly rare strongboxes that you can find in secret rooms or on the mangled remains of your enemies. Your loadout includes a pistol and two rifle class weapons – choose from fast firing submachine guns, devastating shotguns, high damage assault rifles, brutal machine guns, flamethrowers, rocket launchers, lightning guns, and more. Armor up for protection against physical, thermal, and chemical attacks, then round out your arsenal with auto-turrets, grenades, and special high damage ammo to rip through the undead before they rip through you.
AMAZING RPG-STYLE UPGRADES
The Assault, Medic, and Heavy Gunner classes each have unique upgrade trees, giving each character 19 skills to customize. Hundreds of guns and armor pieces have a range of grades and a powerful RED version when you reach high levels. In addition you can add powerful augmentations to your guns and gear which enhance core properties like damage and rate of fire, but can also improve reload time, resist damage, and heal.

SAS: Zombie Assault 4 is recommended for players 12 years of age and older, and the fantasy violence, gibs, and zombie blood are to be expected given the survival theme. We have included a "Gore" setting on the Options screen specifically for young or sensitive players, and this removes the blood and gibs when Gore is toggled Off.
This Action game offers engaging gameplay and regular updates for mobile players.

Community Insight:
This game is incredibly fun. Although, it would be nice to be able to customize the button locations.
Possible drop of a black box during nightmare mode shortly after acquiring so called black box the game crashes really enjoy the gamealso the enemies are like basic level enemies during nightmare mode whaaaa.
Can you please add a offline survival mode where you survive endless waves of zombies that evolve each wave you beat and add boosts and power ups that you gain after each wave beaten.
Love this game. Been playing before covid.
This is the best game ever. Well actually we havent played because we found this phone on the street.
Our boyfriend loves the game. The end.
Thm nhiu sng vo game chc chn ln th gii.
Wish you could chat like in the online version, but overall great game. Some bugs, but youll have that.
Great game play and of courseeee tons of action.
We wish they had more content and kept adding on to this game.
No words can describe what this game means to us and Im so thankful that it hasnt disappeared. Amazing game is all we can say, thank you for being part of our childhood back in 2014.
Ive been playing this game on and off for years now and its fantastic.
Fun zombie killing game to pass time and relax check our socials out @InShaneOneTV.
This is COD zombies in third person you also have armor options and can customise the guns you get from crates. The game is very free to play (FTP) friendly with some pay options but Ive never spent a dime and Im stacked. Also theres a way to get money really fast and thats by playing level 3 and saving a 60 survivors you get 300 to 900 per person you save and you get money at the end of the level. We average around 20k-40k per level.
Brought back memories when we were a kid.
We love this game we cant wait for an SAS5 but plz dont shut down the servers like in SAS3 we were really upset when that happened.
In our opinion one of the best mobile games ever and Ive has played lots of mobile games cant wait for the sequel.
Good game, needs more maps and abilities tho, other than that, we play everyday, if that says anything got level 93, repeated weapons in the boxes.
Childhood game and it still hits hard and is still a good game.
This game is good with its missions but if the joysticks were a bit bigger Id be better at it but besides that we think the devs need to come back to it like more maps and guns loud outs and new zombies this game has a crazy amount of potential if the devs really look into this they could literally make a first person shooter and would be game of the year. Devs please add stuff in and make this game your signature.
We used to play this game in 2017 and in 2025 it is so fire, and it is worth wasting time.
Pretty much the best mobile co-op experience! Plays great with touch controls and even better with controller. The only improvement that would make this game practically perfect if you could see a reload indicator for your teammates (like a small timer over player). This would greatly improve tactical communication, so hopefully this recommendation is taken into account.
Worst game Ive ever played Five stars .. Also stop being lazy developers.
Bugs when you spawn trap zombies sometimes youll get a strongbox to drop just outside of your reach. Why doesnt it drop the strongbox inside the map in reach of the players character to pick up.
The best game in history still gains players till this day because of how popular and fun it is if it wasnt for this game we wouldnt be here today probably the world would have ended if not for this game.
Great amazing game!!! Would love to see a Sas 5 in great detail and story Id pay 5 or 10 bucks for the game too, spent money in this one happily.
This game is so pretty and whimsical.
One of the best games we have ever played but the problem they are too slow for updates please update the game for new weapons and new maps and thank you for this game.
Been a fan since 3. These games are fun.
We would buy this even if it costed 20 dollars, this game is actually good for a mobile games. Because some have ads coming at you. But this has basically no ads, only ads for like getting the free money for ads but overall it is one of the few good shooters we have on our mobile device.
Ive been on this game for hours its a top down looter shooter with strong gun play the class system in the game is pretty basic DOWNLOAD IT NOW.
Ive played this game 3 years ago and we still play this game but we wish it had more updates and more maps.
We dont care what anyone says about this game. This game is amazing. This game was our childhood all the way up until it was first made. Anyone who hates the game can go in touch grass.
Love this game we have no problems with it prices are a little high for buying crates with real money but Im fine funding sas5 (please make it) we wish there was a friends or a chat system where you could find people on multiplayer and keep playing with them or add them to play later that would be so very helpful.
Old game we used to play still good game.
This game is og and awesome but we need sas 3 back, those who know that was a real deal of a game.
Played this since it came out back on pc and when kongregate was still a huge name when flash was alive.
The best game for trips and js playing in general.
Amazing gameplay with an even better support staff.
Just grind and youll get better, there is hidden areas, at level 20 things get stupid hard, gotta go fast.
Man we grew up on SAS 3. 4 is great too. WE NEED SAS 5.
One of, if not the best games ive every played in our life. This game has carried us through our childhood and is so entertaining and enjoyable, if im bored then immediately this is the game. Its so attentive and honestly we hope this game never dies out.
Wow bro we use to always play this back in 2017-2019 man this games still so good even if its old great game maybe add a few more maps and yea but.
Us n our boyfriend play all the time its soo fun.
This game is amazing a lot of room for growth and advancement but Im sure yall already stopped adding to this game. However this is still one of our most favorite games on our phone.
When we get very bored or usually travel, we play this game nonstop. This game is versatile never gets boring and also its very fun.
So fun!! Ive been playing since 2014 and thats a long time.
Please add new maps. An all time favorite of ours.
This game has brought us so much joy when we were younger we always played every day and this is truly one of the best mobile games ever.
