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.
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.

Amazing game 👏👏👏
I used to play this all the time on my kindle fire and when you guys made it unavailable in Game Center I was saddened because I had a lvl43 medic with three black strongboxes, never the less I downloaded it on my mobile phone and I am very glad to see mechanics constantly improving. The gameplay is so unique, especially for a more action oriented game. That said strategy still helps you out, and the overworld action concept is fairly unexplored by most other game makers. You guys took your overworld mechanics from games like bloons td and made an action game that was more than enough to please any player. I would like to see more rankor guns and also I would like to see rankor armor as well please keep expanding the possible arsenal!! Cheers to my favorite game guys!!!

Great but could have adjustments.
I understand that there are a lot of players who have more time and money then the average player. But not to lie, it feels like a shortage on the amount of weapon choices you even have in the higher levels. Don’t get me wrong the red and black weapons are a unique way to add more guns for higher levels. But it’s just a powerful version of the weapon you had early game. Maybe a few new ones added over a long while for updates. But still unless you have time the cash gain is kinda slow once you hit a full set of reds since your getting 30k+ for a lvl40 co-op mission (not including special missions with dedicated drops or events). Which seems like a lot but it’s not when upgrading higher tier weapons. The main thing I dislike is the Strongboxes, I know every game needs some sort of RNG loot system, but this is just horrible. The strongboxes never drop at all making new equipment hard to get unless you buy them with in game cash (lowest quality) or with real money (better or highest) which isn’t really what you need for high level play. Download at your own convenience I still think it’s worth it but the devs need to increase experience since leveling takes forever even at lvl 40. Unless I’m doing it wrong.
So i had this game since it first came out, I even played sas3. the game has good customer service which is a plus. However they have only had like maybe 5 updates the whole time they have had this game. They have not added any new maps and they only recently just started adding new guns but you have to buy them with real money. I feel that ninja kiwi doesn't care much for their mobile games, because sas 4 on the computer has way more, the mobile version can't even compare, if this game was taken care of just a little bit better I would rate it higher but since I've had it for as long as i have, I'm really disappointed with the company for making such a fun game and not maintaining it a a satisfactory level. I play other games where the company is always trying to spice their game up for the seasons and holidays, ninja kiwi doesn't do that so it makes a lot of their games really dull, it just loses its fun potential really quick. And it makes me sad because ninja kiwi puts so much effort in a game then release it but then they just ditch it and don't keep up with the glitches and other issues that they might have. I just wish that they did a better job at that because they really do make awesome game.
