Faction War

Overview

Faction War is a multi-faction sandbox brawl mode. You choose a faction to join, and all Bosses on the field belong to different factions. Same-faction units do not harm each other, while different factions fight each other. There are no fixed waves and no clear conditions — this is the most free and chaotic mode in BossRush.

Entry Requirements

• Naked: Cannot wear any equipment
• Carry a Faction Banner (purchased from the base merchant)
• The Faction Banner is consumed upon entry

Faction Selection

Your faction is determined by which Faction Banner you carry:

• Random Banner: Join a randomly assigned faction / Randomly join one of 5 NPC factions
• Scav Banner: Join the Scav faction
• USEC Banner: Join the USEC faction
• BEAR Banner: Join the BEAR faction / Since the base game has no BEAR presets, BEAR faction units receive a 150% stat boost (×2.5) as compensation
• Lab Banner: Join the Lab faction
• Wolf Banner: Join the Wolf faction / Prioritizes spawning all unique Wolf Bosses; remaining spawn points produce minions promoted to Boss tier
• Lone Wolf Banner: Join the Lone Wolf faction / Do not join any faction, hostile to all Bosses

Core Mechanics

Faction Friendly Fire Rules

• Same-faction units cannot damage each other
• Different factions are automatically hostile
• Lone Wolf players are hostile to all factions, with no allies

Death Empowerment

When a member of a faction dies, all surviving members of that faction receive stat boosts:

• Per 1 member death: Survivors gain +5% health, firearm damage, melee damage
• Effects stack; the more a faction loses, the stronger the remaining members become
• Health increase also restores an equal amount of HP

Starting Gear

• Same random starting gear as From Scratch
• Snow maps additionally issue cold-weather gear (helmet + armor)
• Lone Wolf players receive extra supply items

Boss Spawning

• All Bosses spawn at once when the mode starts
• Each faction's spawn points are assigned by distance; your faction gets the closest spawn points
• Dragon Descendant appears at most once per session
• Skyburner Dragon Lord does not appear in Faction War

Arena NPCs

All three NPCs appear in Faction War mode:

• Awen (Courier): Provides item storage and retrieval services
• Dingdang (Goblin Smith): Provides Reforge and shop services
• Yuori (Nurse): Provides healing services

Mystery Merchant

When the mode starts, a Mystery Merchant appears in front of you, offering 13 categorized shops:

• Firearms: All firearms / Price multiplier ×10
• Melee: Melee weapons / Price multiplier ×10
• Attachments: Weapon attachments / Price multiplier ×10
• Ammo: All ammo (purchase auto-refills) / Price multiplier ×1 (original price)
• Helmets: All helmets / Price multiplier ×10
• Armor: All armor / Price multiplier ×10
• Backpacks: All backpacks / Price multiplier ×10
• Totems: All totems / Price multiplier ×10
• Masks: All masks / Price multiplier ×10
• Medical: Medical items and injectors / Price multiplier ×10
• Food: Food items / Price multiplier ×10
• Decoys: Decoy items / Price multiplier ×10
• Other: Tactical consumables, etc. / Price multiplier ×1

The merchant is on your faction and has extremely high HP, making them virtually unkillable.

Summon Coalball

The main interaction option with the Mystery Merchant allows you to summon a "Coalball" — a pet NPC combat companion that joins your faction. Coalball follows you and participates in combat, helping you fight Bosses from hostile factions.

Tactical Consumables

Faction War provides 4 exclusive consumables (purchasable from the Mystery Merchant's "Other" shop):

• Taunt Smoke Bomb: Spawns random-faction Bosses at the 10 nearest spawn points
• Chaos Detonator: Spawns random-faction Bosses at all spawn points across the map
• Hunter's Whistle: Forces all hostile Bosses within 50 meters to chase you
• Blood Hunt Beacon: Forces all hostile Bosses across the entire map to chase you

Every 10 Boss kills, the system automatically grants 1 Taunt Smoke Bomb.

End Condition

Faction War has no explicit win/lose condition. It is an open-ended sandbox mode. Leaving the arena scene ends the session.

Strategy Tips

• Consider the Boss pool strength distribution when choosing a faction; Boss power varies significantly between factions
• Lone Wolf mode is the most hardcore choice — you have no allies, and all Bosses are enemies
• Make good use of Taunt Smoke Bombs and Chaos Detonators to create chaos and let Bosses from different factions wear each other down
• The death empowerment mechanic means the longer the fight goes on, the stronger surviving Bosses become
