IONIZATION is a work-in-progress singleplayer 3D first-person shooter action and post-apocalyptic standalone video game, based on a custom Half-Life 1 SDK known as PrimeXT SDK and running on Xash3D FWGS engine. The main idea originated in 2011, being inspired by the Half-Life series, the modification Paranoia and other creations of the BuZZeR level designer. An Intro Demo version was released on March 5th, 2024. It is an opening part of the storyline, which takes about 15 minutes to complete. This build performs an introductory function and it does not reflect the final quality of the project.
