1. Preparation Before Crystallizing the Knife
Zombie Battle mode offers only one basic knife (the wrench), so direct kills can be slow. Instead, you must completely crystallize specific weapon categories to unlock special knives.
2. Weapon Categories for Unlocking Knives
Here are the main categories required to open up various melee weapons:
- Katana: Crystallize 8 out of 10 pistols
- Standard Knife: 4 marksman rifles
- Shovel: 9 shotguns
- Axe: 24 SMGs
- Baseball Bat: 9 LMGs
- Special Blades: 12 sniper rifles
- Other Types: 27 assault rifles
- Tamper, SMRS & Others: All weapons must be crystallized
3. Tier Level Requirements
Your tier significantly impacts whether kills count toward crystallization.
- Example: Shotguns require tier 31
- All guns unlocked at tier 50+
Tiers increase only through playing, not through shortcuts.
4. Easter Eggs & Secret Computer Codes
Important computer locations:
- Sakura — Code: ص۰۴ ۱۸
- Sanitarium
- Outpost / Nachlar Plan
- Killse
Tip: Each computer can be looted once per match; higher days yield better loot.
5. Pro Tricks for Faster Crystallization
- Take down large zombies with the knife for more currency
- Use give-up respawn to quickly return to objectives
- Exploit the crystal challenge bug with a chopper to instantly smash crystals
6. Best SentiGun Choice
The Keno is the top pick for close-range — unlockable after taking the left upgrade path.
