Sometimes spawns a biter when a tree is destroyed.
Mods introducing new content into the game.
Changes to enemies or entirely new enemies to deal with.
like,if a new play just install a mod at early gmae,they probably will be kill by bad luck,maybe a biter free period at start and every spawn 100 biters.
The player can kill a few dozen biters with their starting pistol and ammo, easily since this mod produces them one at a time.
