# EnemyPopulation

This datablock is used to select enemies by [EnemyGroupDataBlock](https://gtfo-modding.gitbook.io/wiki/reference/datablocks/main/enemygroup) through filters.

While technically you can have several population blocks, usually only the first block is used both in-game and by modders.
