SAS: Zombie Assault 4

By Ninja Kiwi

Open iTunes to buy and download apps.


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.

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.

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.

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.

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.

Currently in development - private matches and events. Please be patient and know that private matches is a top priority.

Please Note: SAS: Zombie Assault 4 is free to download and play (aside from internet, carrier, data, device, and other services for which the player is financially responsible), but some in-game items can be purchased with real money. You can turn off the payment feature by disabling in-app purchases in your device's settings.
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.

Awesome but needs minor changes

I love this game, it's addicting and the idea is cool, but some things make me kinda annoyed. First thing is nightmare. I think they should up the min Level for nightmare. I'm only level 63 and when I get matched up with 3 other level 35s, it's very hard to get a decent game in, let alone kill a savage dev. And if they don't, at least balance the game a little when playing with lower levels. One of the things I hate most is when people leave games at the last second. Once one person leaves, the rest follow. You shouldn't be allowed to leave after the 5 sec count down. Every time I get matched with lower level people and when I finally get decent players, they all leave at the last second so it's too hard to play the match with 3 or less people. Other than this it's a fantastic game and you will enjoy this game.

Must play

I have been playing this game since about the dawn of the series creation. I love every single aspect of this game. Does it need a little bit of work and minor balancing? Yes, but the fundamentals of this game is what makes it such an addictive and potentially a multimillion dollar game. It feels as though the games full potential has not been harness. Why stop at mobile gaming. This game of work perfectly on a PlayStation four or Xbox one has an indie game. Adding micro transaction purchases and the ability to play with friends, and you might have one of the next biggest hits. This game is a gateway to the kind of zombie shooter should be. I, William Carlson, genuinely believe that this might be one of the most original video games of its kind. Thank you Ninja Kiwi.


This game needs free range chat, a way to leave the match before it starts on multiplayer, also, you shouldn't be able to do a nightmare mode game with only 2 people... the game countdown timer should restart if a player leaves. Needs to have a chat available before the game starts. Maybe, have a ready button to start a match or have a kick button so that a team of level 60's isn't forced to do nightmare mode with a level 38... there have been a couple crashes but they are few and far in-between. Maybe a friends thing so you can do custom matches with people. And the event games like "last man standing" should have private matches, even if they don't count towards event points, just so people can test themselves against friends.
