Arctic Striker (S-Tier, Offensive)

Credit Cost: 3,500

The Arctic Striker is an S-tier offensive class built around frost-based damage and crowd control. Its abilities apply freeze and slow effects to groups of zombies, letting you dictate the pace of combat by preventing the horde from overwhelming your position.

What Makes It Strong

• Frost AoE damage that hits multiple zombies simultaneously
• Slow and freeze effects that give you breathing room during dense waves
• Exceptional credit-to-power ratio — at 3,500 credits, it punches well above its weight

How to Play It

The Arctic Striker rewards players who think about positioning. Instead of holding a fixed position and shooting, use your frost abilities to slow incoming groups, then reposition to the next angle while they're frozen. This hit-and-freeze kite style is incredibly effective in solo play and pairs beautifully with high-DPS weapons for team scenarios.

Pro tip: Don't waste your freeze abilities on small groups. Save them for the massive zombie clusters that arrive in later waves. A well-timed frost ability on a 50-zombie horde is worth ten times the same ability used on five stragglers.

Bastion (A-Tier, Defensive Tank)

Credit Cost: 8,000

The Bastion is a defensive tank class designed to absorb damage and hold chokepoints. When zombie waves start hitting harder and your offensive classes are struggling to stay alive, the Bastion steps in as the unbreakable wall that gives your team time to breathe.

What Makes It Strong

• High damage resistance that scales with wave difficulty
• Defensive abilities perfect for holding narrow lanes, doorways, and stairwells
• Aggro management — enemies naturally focus on the Bastion, protecting squishier teammates

How to Play It

Your job as a Bastion is simple: don't die, and don't let zombies pass. Anchor yourself at the most critical chokepoint on the map — usually a narrow corridor or stairwell — and let the zombies come to you. Use your defensive abilities to mitigate damage while your teammates handle the actual killing.

Pro tip: Communicate with your team about where you're anchoring. A Bastion holding the wrong lane is a wasted slot. The best Bastion positions are points where the entire zombie horde funnels into a single kill zone.

Celestial (S-Tier, Support/Healer)

Credit Cost: 50,000

The Celestial is the most expensive class in Survive Zombie Arena, and for good reason. This S-tier support class provides team-wide healing and sustain that becomes absolutely essential in late-game co-op runs. When waves 40+ start one-shotting players, the Celestial is the reason your squad survives.

What Makes It Strong

• Powerful healing abilities that affect multiple teammates simultaneously
• Scaling sustain that keeps up with increasingly lethal late-game damage
• Team-multiplier effect — a good Celestial makes every teammate significantly more effective

How to Play It

Position yourself behind the frontline where you can reach all teammates with your healing range. Your priority is keeping everyone alive, not dealing damage. Let your offensive classes handle kills while you focus on timing heals around big damage spikes. The best Celestial players anticipate when the team is about to take heavy damage and pre-cast heals before it hits.

Pro tip: The Celestial is a co-op class through and through. If you primarily play solo, 50,000 credits is better invested elsewhere. But if you have a regular squad, the Celestial will transform your team's survivability.

Necromancer (A-Tier, Summoner)

Credit Cost: 25,000

The Necromancer is a summoner class that turns the zombie horde against itself. By harvesting souls from fallen enemies, you raise undead minions that fight on your behalf. The more zombies you kill, the bigger your army grows — creating a snowball effect that gets stronger as waves intensify.

What Makes It Strong

• Self-scaling army that grows naturally as you kill zombies
• Minions absorb aggro and act as a physical barrier between you and the horde
• Strong solo potential for players pushing toward infinite waves

How to Play It

The Necromancer requires a fundamentally different mindset. You're not just shooting zombies — you're managing an army. Kill clusters of enemies, harvest their souls, raise your minions, and position them as a frontline. When your army is surrounded by a fresh wave, detonate them for massive AoE damage, then rebuild. This cycle of harvest → summon → detonate → repeat is the core of the Necromancer's power.

Pro tip: Never detonate your minions when you're exposed. Always ensure you have cover or a chokepoint behind you before triggering the explosion. The brief window between detonation and resummoning is when you're most vulnerable.

Medic (B-Tier, Healer)

Credit Cost: Free (default class)

The Medic is the class every new player starts with. It provides basic healing capabilities that are helpful in co-op but lack the scaling and raw power of the Celestial. Think of the Medic as a stepping stone — it teaches you the fundamentals of support play while you grind credits for a better class.

When to Use It

• Your very first games while learning the ropes
• Co-op lobbies where no one else is playing a healer
• Budget runs where you're saving credits for a specific unlock

When to Replace It

As soon as you can afford the Arctic Striker (3,500 credits) for solo play or the Celestial (50,000 credits) for dedicated support, the Medic should be retired. It simply can't keep up with late-game wave pressure.

New Class (B-Tier, Starter)

Credit Cost: 1,500

The New Class is the cheapest unlockable class in the game. It offers a modest power bump over the default Medic and serves as an affordable introduction to the class upgrading system. It won't carry you through endgame content, but at 1,500 credits, it's a worthwhile early investment that makes the grind to your next class noticeably easier.

Best Use Case

Treat the New Class as a stepping stone. Unlock it early, use it to farm credits faster, then upgrade to the Arctic Striker or Bastion as soon as your budget allows. Every class above it offers significantly more power for the waves you'll be facing.

Frequently Asked Questions

Which class should I unlock first? For most players, the Arctic Striker at 3,500 credits is the best first unlock. It's affordable, powerful, and versatile enough for both solo and team play.

Is the Necromancer better than the Arctic Striker? They serve different roles. The Arctic Striker is better for raw damage and crowd control. The Necromancer is better for long-term solo scaling. If you play mostly solo and want to push deep waves, the Necromancer has higher potential. If you want immediate impact and easier gameplay, the Arctic Striker is the safer pick.

Can I switch classes during a run? No. Class selection happens in the lobby before the wave begins. Choose based on your team composition and the difficulty you're tackling.

What happens if I buy a class I don't like? The class is permanently unlocked, so you haven't lost anything. You can always switch back to a different class for your next run. Credits spent on class unlocks are a one-time investment.
