If you are reading this, you probably already know one thing. This Wild Wild World Challenge is absolutely unhinged. Speed is everything. If you cannot run, you will die. Your main goal is not to fight bosses — it is to make bosses fight each other. You kite them together, let them beat each other up, then sneak in like a rat and loot what is left.
Everything is Crab Wild Wild World Challenge Guide
HP keeps you from getting one-shot, and Healing fixes mistakes. XP makes you stronger and Cooldown reduction keeps your movement flowing. Damage comes last. You honestly do not need much of it if you play this mode correctly.
SPEED
You must start with PRECOCIOUS so your branching evolutions open early.
Then restart runs until you get LEGS.
LEGS gives the fastest movement speed early and eventually gives you free ARMS through BIPEDAL. The speed loss from BIPEDAL is absolutely worth the free ARMS.
You need speed because bosses spawn constantly. If you cannot outrun them, you will get bonked, then get mad, then question your life choices.
Running lets you kite bosses into each other.
Once they start fighting, they usually forget about you — this is where the run is actually won.
You dart in, loot, and run out. Rat life.
The basic dash is enough early.
If you get SLITHERY, grab SLIDE — it is a huge quality-of-life upgrade.
HOLLOW BONES, DEXTEROUS, AGILE, STOMACH, and WINGS all help keep your speed high.
Now you make yourself fat.
Your most important HP evolution is HUMP.
Upgrade its rarity whenever you can. Big HP bar = happy life.
Pair it with FORAGER so you see more healing food.
Add MORE MASS, SUBCUTANEOUS FAT, and ROBUST to inflate your health pool even more.
CHEEK POUCH is great early because it lets you eat while running.
Later it becomes less important once your reach gets big.
I personally skipped damage reduction and dodge.
Speed + raw HP was more than enough to survive.
This is what actually wins the run.
CARRION is your most important XP evolution.
Upgrade it hard. Let bosses kill each other and farm the aftermath.
CARNIVORE is next so dead enemies drop meat.
Everything that increases reach and eating speed makes leveling much faster:
ARMS, SIZE, TAIL, STOMACH, and FUNGOID.
More food touched = more XP gained.
SYNAPSE
SYNAPSE is king here. Take it if you see it.
DEXTEROUS and AGILE are also great for keeping your movement and attacks flowing.
DMG
I did not prioritize damage, but if you want it:
Focus on ABILITY damage.
Start with BEAK, then upgrade into SHARP BEAK to pierce boss plating.
Once you unlock PINCERS, they become your main weapon.
Later grab PISTOL PINCER or SHARPEN for big bursts.
Damage is helpful — but survival is mandatory.
DNA
This mode gives you a lot of DNA. Use it.
Save DNA early for rerolls.
Mid and late game, start upgrading your best evolutions to LEGENDARY.
Top priority legendaries:
-
LEGS
-
ARMS
-
HUMP
-
FORAGER
-
CARRION
-
STOMACH
-
WINGS / SLIDE
Once these hit legendary, the run becomes dramatically easier.
