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 decreasing available 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 10%.
• The Hazard Level will also affect wave modifiers, such as "time until the next wave" and the enemy composition.
• Increased Hazard level affects the number of enemies present in a mission, particularly during swarms. For more information, see Creatures.

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

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:

• The following are neutral creatures and don't scale at all: Loot Bug, Golden Loot Bug, Maggot, Silicate Harvester, Cave Vine & Naedocyte Cave Cruiser

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