Many generations ahead our own, evolution has given another step... But this time, it's not on our side. HESK: Hyugaren is a single player T.C. for GZDoom 1.8.2, which includes a lot of new features, such as totally reworked gameplay mechanics, new graphics, new sprites, new sounds, new music, new gore system, new skybox (Hyperskybox), new liquids (Hyperwater), among many others...
I've uploaded this video here so we can have a repository of documents from HESK in the same place.
You may wanna look into this article, so you understand most of what you see in the playthrough: Moddb.com
In short: Weapons, armor system, health mechanics, some ambience, design details, extra options, new gameplay mechanics (like the ability to aim directly from the iron sights without slowing down the action).
I recommend you look into the article above, everything it's detailed there, plus some more things I forgot to show in the video (and other news about the mod).
Thank you!
