Difficulty Scaling

This article may need cleanup to meet quality standards.
Please help improve this if you can. The Discussion page may contain suggestions.

Hazard Levels

Hazard levels, along with player count, determine the amount of enemies present in a mission and during swarms; as well as an increase to the amount of damage they can absorb and the amount of damage they deal to players. Hazard Levels contribute to a Hazard Bonus, which determines the rewards at the end of the mission.

Normal Scaling

Depending on the selected Hazard level and the amount of players in a game, the difficulty is dynamically adjusted through several factors:

• Increased Hazard Level increases: enemy and environmental damage; friendly fire; as well as health after a revive.
• Increased player count increases enemy damage even further.
• Additionally, Hazard 5 reduces the maximum health the player will regenerate to, from 15% to 5%.
• The Hazard Level will also affect wave modifiers, such as "time until the next wave" and the enemy composition.

Below is a table listing several modifiers for each Hazard Level ( x / x / x / x denotes the amount of players in the game).

Hazard Icon	Hazard Level	Enemy Damage	Enemy Attack Speed	Enemy Movement Speed	Friendly Fire*	Environmental Damage	Revive Health	Max Revive Regeneration
	1 - Low Risk	0.50 / 0.50 / 0.50 / 0.50	0.8	0.8	0.1	0.75	0.60	0.15
	2 - Challenging	0.70 / 0.80 / 0.90 / 1.00	0.9	0.9	0.2	1.00	0.50	0.15
	3 - Dangerous	1.20 / 1.30 / 1.40 / 1.50	1.0	1.0	0.3	1.00	0.40	0.15
	4 - Extreme	2.00 / 2.15 / 2.30 / 2.50	1.25	1.0	0.4	1.33	0.20	0.15
	5 - Lethal	2.60 / 2.80 / 3.00 / 3.20	1.5	1.2	0.7	2.00	0.05	0.05

Resistance Scaling

Shown below is a table of multipliers for enemy count and enemy damage weakness. (Separated by size classification), only affected by the amount of players and hazard level. The enemy damage weakness is a modifier to all damage dealt to enemies by players.

Damage dealt to enemy = Damage of Weapon / Modifier.

For damage resistances:

• Loot Bug and Golden Loot Bugs are neutral enemies and don't scale at all.
• The following are normal enemies: Glyphid Spawn, Glyphid Swarmer (Radioactive Glyphid Swarmer), Glyphid Grunt (Glyphid Grunt Slasher, Glyphid Grunt Guard), Glyphid Exploder (Radioactive Glyphid Exploder), Glyphid Web Spitter & Glyphid Acid Spitter
• The following are large enemies: Glyphid Praetorian* (Radioactive Glyphid Praetorian, Glyphid Frost Praetorian), Glyphid Menace, Glyphid Warden, Glyphid Bulk Detonator, Glyphid Brood Nexus, Mactera Goo Bomber (Mactera Ice Bomber), Mactera Grabber, Naedocyte Breeder, Spitball Infector, Q'ronar Shellback & Huuli Hoarder
• The following are extra large enemies: Glyphid Dreadnought, BET-C (Xynarch Charge-Sucker) & Parasites

*When spawned via Mixer Interactivity they count as normal enemies.

1 Player (Solo) / 2 Players / 3 Players / 4 Players
Hazard Level	Enemy Count	Normal Enemy Resistance	Large Enemy Resistance	Extra Large Enemy Resistance	Special Enemy Encounter Chance
1 - Low Risk	0.15 / 0.25 / 0.45 / 0.65	0.7	0.45 / 0.55 / 0.70 / 0.85	0.2 / 0.4 / 0.6 / 0.8	0.03

There is only a small increase of enemy spawns between Solo and 2 Player to compensate for the loss of Bosco.
