Quality for Biters!

Quality for Biters! adds quality scaling to enemy units based on the current evolution factor.

As evolution increases, higher-quality enemies gradually begin to appear.
The impact is minimal in the early game and becomes more pronounced toward the late game.

Affected targets

• Nauvis:
• All enemy units
• Biter spawners
• Spitter spawners
• Gleba:
• All enemy units
• Gleba spawners

Design intent

This mod is not intended to drastically change early-game balance.
Instead, it increases long-term pressure by making late-game enemies tougher and more varied.

On higher difficulty presets (Death World / Marathon),
defense planning and maintenance become significantly more important.

Dependencies

• Quality mod (required)

Documentation

• Design decisions and guarantees are documented in spec.md.
