Infinite Hell & From Scratch Guide

Infinite Hell

No end. Bosses gain +2% stats per wave. Survive as long as you can.

Prep

Best gear, best weapons, max ammo
Dragon King Set (dash + fire immunity) is critical late
Cloud Rider for aerial dodging, Reverse Scale for emergency saves

Pacing

First 20 waves = warm-up (heavy hitters excluded) — find your rhythm
Ammo shop near signpost — resupply often
Cash within 2m auto-flies to you, but you need to walk into range first
High-quality item every 5 waves — don't miss it

Late Game

Past wave 50, Boss stats get terrifying
Never stand still. Always moving, always shooting
Boss Filter to reduce spawn rate of the worst Bosses
Milestone rewards (every 100 waves) scale exponentially

Achievements

10 waves / 25 / 50 / 100 / 200 — escalating milestones
10 waves no damage: Iron Will
10 waves no healing: Iron Man Challenge (hidden)

From Scratch

Random start, grow from nothing. Adapt or die.

Opening

Starting gear is random — don't restart for perfection
Check your weapon + ammo, adapt your playstyle
Got melee only? Melee-clear first waves
Only 3 medical items — they're precious

Wave Strategy

1-2: Weakest grunts, easy loot
3-5: Stronger grunts, no Bosses — focus on gear upgrades
6-10: 1 Boss appears — kill it for drops
11-15: 2 Bosses — watch positioning, don't get pinched
16+: Full pool — gear should be solid by now

Gear Upgrades

Enemy gear quality scales with wave number (late = Q5-6 drops)
After each wave: check crates, replace weakest slot first
Boss drops > grunt drops

Achievements
