SAS: Zombie Assault 4 - Intense zombie shooting

About the game

Eliminate the undead! Experience an exciting array of upgradable weapons and armor, along with distinctive class abilities, all while teaming up with three friends! Dive into the ultimate zombie shooter on mobile, crafted by the creators of Bloons TD 5.

A viral outbreak on a remote trans-federation planet has unleashed terrifying creatures from humanity's history. An overwhelming and swiftly multiplying horde of zombies poses a grave threat to human survival, with only the elite, heavily armed special forces of the SAS able to stand against them. Select from three character classes, optimize the fully customizable skills tree, and choose from countless weapons and armor pieces to create the ultimate hero for vanquishing zombies. Engage in action-filled, demanding levels in solo mode or through cooperative multiplayer with three others, giving a last fighting chance to our devastated civilization.

EXCITING ACTION

Zombies fill the screen, shattering into pieces under your relentless fire. Each of the 17 different types of zombies possesses unique attacks and behaviors, and they can upgrade - revealing horrifying new abilities as you advance in the game. Just when victory seems within reach, fierce boss zombies will pursue you, spewing acid worms or charging at you in rage mode. Discover their strengths and weaknesses as you lead the charge across seven story-driven maps, each featuring distinct victory conditions.

UNBEATABLE FOUR-PLAYER CO-OP

Quickmatch with up to three players of comparable skill and utilize everyone’s selected custom skills and weapons to form a formidable team. Strategize turret placements, unleash powerful room-clearing abilities like Assault Team, Aerial Bombardment, and Zombie Antidote, and maneuver physical objects to create temporary shields while you wreak havoc.

ABUNDANCE OF EPIC LOOT

Over 160 extraordinary firearms and armor pieces are securely locked away in increasingly rare strongboxes found in hidden areas or on the defeated foes. Your equipment includes a sidearm and two rifles - opt for rapid-fire submachine guns, powerful shotguns, high-damage assault rifles, fearsome machine guns, flamethrowers, rocket launchers, lightning guns, and more. Equip yourself to defend against physical, thermal, and chemical assaults, then enhance your loadout with auto-turrets, grenades, and specialized high-damage ammunition to take down the undead before they take you out.

The Assault, Medic, and Heavy Gunner classes feature distinct upgrade paths, allowing you to customize each character with 19 different skills. Numerous firearms and pieces of armor offer various grades, with a potent RED version available at higher tiers. Moreover, you can apply powerful enhancements to your weapons and gear that boost essential properties like damage and firing rate, as well as improving reload speed, damage resistance, and healing capabilities.

It is important to note that SAS: Zombie Assault 4 can be downloaded and played for free; however, certain in-game items are available for purchase using real money. You have the option to disable this feature by turning off in-app purchases in your device's settings.

SAS: Zombie Assault 4 is recommended for players aged 12 and older, given its fantasy violence, gore, and zombie blood due to its survival theme. There is a "Gore" setting available on the Options screen catered to younger or more sensitive players, which eliminates blood and gore effects when deactivated.

The Very Basics for New Players (Level 1-35)

Hello everybody, welcome to the SAS 4 Bible! This Bible will teach you how to be the best player you can be, even at low level!

At the start, you have to choose a character. There's 1 (Medic) 2 (Assault) and 3 (Heavy). My suggestion is 2 & 3. xd

Play the Onslaught map until Zombie Pods is unlocked.

Q: How many onslaught runs do I need to do till I can play on Zombie Pods?

A: Usually takes 3/5 games, depends on your kill counts.

Q: Why Zombie Pods?

A: Zombie Pods is by far the best way to farm free crates. (Or Strongboxes. Whatever.) You can get at least 1 to 3 boxes every run you make, meaning you can find guns and armor very fast for starting gear.

Q: How long for low level pods runs?

A: About 2 minutes.

Q: What guns should I use during Onslaught?

A: Use any of guns you've got, just remember to avoid guns/armor that have movement penalties. (Just in case you didn't get any guns or armor, use HVM 001.)

Q: Why HVM 001?

A: Cause it has low reload/almost the same damage result of your Z-Armtech guns. Only difference is that it's lighter.

After level 10, up to 35, look for Exp contracts:

Maps that I recommend you to spam are:

1. Uranium Mine

2. Sea Lab (With Shredder Disk Thrower for best results.)

Every other map is wack for Exp grinding.

Skills to pick for low level:

ASSAULT:

1.Adrenaline

2. Reload

3. Speed

4. Killing Spree

5. 1x Stim Shot

HEAVY:

1. Hold the Line

2. Speed

3. Tough Body

4. Reload

5. 1x Die Another Day

MEDIC:

1. Medkit (13 points max.)

2. Bio-Cleanse Bomb

3. Speed

4. Reload

Skills you should avoid at all costs:

HEAVY:

1. Concussion (1 is fine, anything above 1 is useless. Also, if you wanna use Concussion skill on Heavy you'll need a multi-pellet gun such as a shotgun or a high RPS gun like the Proposition.)

2. Heavy gear (I'm pretty sure you can get all maxed resistances without heavy armor like Hardplate armor so this one is kind of a waste.)

3. Die Another Day (1 is a must no matter what, anything over 1 is a waste.)

4. Aerial Bombardment (No damage at all, just shakes your screen and everyone else's screens. Literally useless even with only 1 point. Unless you're going for the achievement never use.)

5. Brute Strength (nope 0dmg)

ASSAULT:

1. Deadly Force (25% of base damage,garbage Use Titan HUD helmet instead for 32% unless you want a full DPS build.)

2. Assault team (Like Bombardment, only good for the achievement.)

3. Close Quarter Combat (CQC) (-1dmg with 25 points on it, seriously don't recommend.)

4. Gun Mod Expert (GME) ( Reduces gun augmenting price, it's okay if you're low on money, but afterwards I'd suggest gathering the money and items that you want maxed out and reset after you finish it, make sure you can afford the 1x reset cost or that you still have a free reset.)

5. Stim Shot (1 Stim Shot is a must, anything above 1 is just a waste like Die Another Day.)

MEDIC:

1. Bad Blood (??? Why don't you shoot instead of putting points into this useless 0dmg CQC skill?)

2. Revive (You better avoid this one if you're going to be a meta Medic, unless you changes your mind and wanna be a real Medic.)

3. Antidote (0 points is a must cause even with 25 points in this skill it barely kills a worm in 2 seconds.)

4. Final farewell (Why choose to die and give medkits to stranger when you can survive and give other people your medkits and provide DPS?)

5. Protective Aura (uuuhhh wtf?)

SAS skills you should avoid at all costs:

1. Field Supplies (TRASH, unless using Jupiter/Hotspot/HIKS 3100/Jagfaust. If so, use 3 points max for High Damage Ammo (HDA) farming, but for black versions only. Don't farm HDA on red guns.)

2. Grenade Damage (Uh... Well at least if you have T-189 MGL it increase the damage by 320% or so but still 0dmg.)

3. Health Regen (Just use Bio instead! OMG such a waste of valuable skill points.)

4. Pay Grade (This only increases the end-game money result. This doesn't affect in-game money loot. But it's quite good if you're just doing singleplayer and running contracts, by the time you reach level 100 you'll have around 100M credits with 25 paygrade, but even then I don't recommend this one.)

5. Energy Boost (idk why this exists lol you tell me)

6. Recovery Time (This too, who chooses to be dead?)

7. Energy Regen (It's good on Medic because if you want to spam Bio-Cleanse Bomb and medkits it's very good. 16 max points for spam build.)

SAS skills you should use:

Toughness 0-25 (Use only if you are going for a high HP build. Choose 0 or 25, can't be lower or Medic must be 0 or 25.)

Reload 0-6 (6 with medusa helmet and 9 with other helmet)

Body Armor Expert (BAE) 0-25 (Start building BAE at level 75.)

Critical Shot 0-25 (Use this for certain guns such a Hornet/Proton Arc/Shockfield with Adaptive. Just to remind you guys 25crit vs 1crit is not quite different, 1crit 0sec, 25crit +1sec thats your CRIT DMG BONUS.)

Movement Speed 0-25 (Highly recommended, you must have minimum speed at 70% to outrun Dark Minion enemies.)

Good guns at low level:

Mobbing: Good against hordes and mobs. (Shambler, Runner, Spitter, Bloater, etc.)

Bossing: Good against large boss enemies. (Regurgitator, Wicker, Zombie Mech, etc.)

Regen: Good for regenerating health.

Multi: Pretty much can do anything.

CM 800 Jupiter (Mobbing)

Hotspot (Mobbing/Bossing)

HVM 004 (Multi) bit trash xd

Lone Star (Mobbing)

Luftplatzen (Mobbing/Regen)

Raptor (Bossing)

RIA 20 Striker (Bossing)

RIA Strikeforce (Mobbing/Regen)

RIA T7 (Mobbing)

Shockfield (Multi)

Stripper (Bossing)

Armor:

Avoid all armor/gear with large speed penalties, use any armor you see with 0% penalty. Some good armor includes Hummingbird gear, Rubicon, and Titan MEM Sprint.

Good luck boys! Don't suck. :)
