Infinite Hell & From Scratch Guide

Infinite Hell Guide

Core Concept

Infinite Hell has no end — Bosses gain +2% stats per wave.
Your goal is to survive as long as possible.

Preparation

Bring your best gear, especially high-quality weapons and plenty of ammo.
The Dragon King Set's dash and fire immunity are critical in later waves.
The Cloud Rider totem provides aerial evasion capability.
Reverse Scale serves as a last-resort lifesaver.

Combat Pacing

The first 10 waves are a warm-up (elite Bosses won't appear) — use this time to get into rhythm.
Use the ammo shop near the signpost to resupply promptly.
Cash pickups within 2 meters automatically fly toward you — no need to collect them manually.
A high-quality item drops every 5 waves — make sure to pick it up.

Late-Game Survival

Boss stats scale cumulatively — beyond wave 50, things get terrifying.
Keep moving; don't stand still to deal damage.
Use the Boss Filter to adjust weights and reduce the spawn rate of the toughest Bosses.
Milestone rewards (every 100 waves) scale exponentially — the longer you last, the greater the payoff.

10 waves: Infinite Hell - Ten
10 waves no damage: Iron Will
10 waves no healing: Iron Man Challenge (hidden)
25 waves: Infinite Hell - Twenty-Five
50 waves: Infinite Hell - Fifty
100 waves: Infinite Hell - Hundred
200 waves: Infinite Hell - Two Hundred

From Scratch Guide

Core Concept

The key to From Scratch is adapting to a random start and using the early low-difficulty waves to quickly accumulate gear.

Opening Strategy

Starting equipment is completely random — don't chase a perfect start.
Check what weapon type and ammo you received, then decide your combat style.
If you got a melee weapon but no gun, you can melee-clear the first few waves.
You only get 3 medical items — they're very precious, so minimize taking damage.

Wave Strategy

Waves 1-2: Weakest grunts, easy to clear, loot for gear upgrades.
Waves 3-5: Grunts get stronger but still no Bosses — focus on looting weapons and armor.
Waves 6-10: 1 Boss appears — prioritize killing the Boss for its drops.
Waves 11-15: 2 Bosses — watch your positioning to avoid getting pinched.
Waves 16+: Full Boss pool unlocked — your gear should be well-established by now.

Equipment Upgrade Pacing

Enemy equipment quality increases with wave number; late-game grunts may drop quality 5-6 gear.
After each wave, quickly check the loot crates and prioritize replacing your weakest gear slot.
Boss drops are generally better than grunt drops.
