"How to install" (aka Readme file) is included into archive. This mod is small, because it changes enemy spawn files which are also have the small size.
This mod is recreation of the Infernal's "Re4generators project complete" mod for the Resident Evil 4 Ubisoft release (2007).
My version looks harder because I've placed regenerators in most places instead of previous enemies. Some original enemies (Ganado) will present in special places.
