Doom Delta is a mod for GZDoom that aims to bring together many elements from the pre-release iterations of Doom, including (but not limited to) the alpha builds, the press release beta, and Tom Hall's Doom Bible. Elements such as the helmet HUD from early alphas, enemy designs, unique characters, and unused weapon concepts return.
The idea is to take these unused concepts and properly flesh them out, giving them the proper attention and polish they deserve. The end goal is to provide a cohesive experience that provides a fun and enjoyable experience with the aesthetic and feel of the pre-release Doom content.
- Four unique characters inspired by the Doom Bible!
- Three fully functional HUD styles, including the helmet HUD from Doom v0.3!
- Reimagined weapons such as the Rifle/Bayonet, the Dark Claw, and the Unmaker!
- New enemies such as the Gargoyle and The Blob!
- Score system with treasure items and kill bonuses!
- New powerups such as damage-absorbing shields and the Chaos Field!
- Vanilla-style sound design!
Your two closest friends, in case you want to change the formality with your otherwordly invaders... or if you run out of ammo.
You're technically not supposed to have this, but this makeshift weapon is a great suppressant for nosey demons.
A standard issue UAC rifle, hailing from the alpha builds. High accuracy and decent damage make this weapon great for picking off demons from farther away. Comes with a bayonet attached to the barrel!
Ol' reliable, with the original barrel from the alphas. Deliver a nasty blast right up close or from far away; the shotgun is great at both!
The UAC's top of the line! Based off of the early SSG design, these two barrels and a hair trigger deliver three times the power of the shotgun.
The machine gun, returning from Doom v0.3! A rapid-fire weapon used to take down demons faster than the rifle. Be careful, though; it's not quite as accurate.
Six barrels of gunfire, guaranteed to rip enemies into shreds! It starts out pretty slow, but the longer you fire it, the faster it gets. Great for tearing through crowds.
Spews out rockets that can reduce even the toughest enemies to mush. Keep your distance, or you'll be mush too!
This weapon uses energy cells to pump out multi-colored balls of hot plasma, reducing demons to a fine mist in a heartbeat. It's just like Christmas!
The UAC's top-secret special weapon, with very few models in existence. Sneezes out a flurry of plasma that decimates whatever (and whoever) stands in its way! You'll bust a nut so good you'll take yourself to Red Lobster.
Hailing from the Doom Bible is this severed demon arm that runs autonomously off of soul energy. Harness it to cast out dark clouds of torment and torture that rip through demons like paper! Runs on human souls.
A cursed mass of flesh and bone hailing from the Doom Bible that unleashes tortured souls to clear a room of a demonic presence. It doesn't have much effect on possessed soldiers or mechanical demons, however. Runs on human souls.
Among the usual Doom items, you can find these new ones lying about:
Shields are inventory items that protect against specific types of damage. Unlike other devices, you can toggle these at will, conserving energy. Each time the shield successfully blocks an attack, energy is consumed. Shield energy can be replenished by picking up another shield of the same type.
A demonic sphere of pure, concentrated hatred. Constantly emits a powerful aura that causes demons to fight amongst themselves.
Carved from the strongest of discarded demon bones, this incredibly durable set of armor absorbs around 80% of all incoming damage. Thanks, Satan!
A jar filled to the brim with tormented souls. Collecting one will lend you eight souls and expand your maximum capacity from 36 to 66 souls!
Fiercely competitive, Lorelei intimidates most people. She was the undisputed champion of her troop's boxing championship. She lost a bet that meant she had to pull her application for a glory post, leaving her with a post on Phobos. No one calls her Lorelei.
Lorelei is fast, and is a crack shot with the standard rifle and her fists. However, she isn't used to using the bayonet or the chainsaw in combat.
Former head of security at Deimos Labs, Pietro grew tired of the overwhelming bureaucracy of the UAC. He was assigned to Phobos by his request, so that he could get away from the epicenter of annoyance while finishing out his term of duty.
John performs well in a variety of scenarios. He excels with shell-based weapons like the shotgun, but has trouble controlling explosive weaponry.
Dimitri is basically stuck in the low ranks of the military, but that suits him just fine. He wants nothing more from life: give him a clear objective and the chance to release aggression through the freely available high-powered firearms, and he's happy.
Dimitri is notably slow, but his resistance to damage and splash damage makes him a living tank. He's experienced with every weapon in the UAC's arsenal.
Thi has a friendly, if straight-laced, disposition. Her father was a career soldier that gave Thi a strong sense of duty and honor. She volunteered for the Phobos post with a desire to have a variety of experience in her military career.
Thi is more susceptible to damage, but is able to dodge projectiles better with her high speed and small frame. She excels with the bayonet and the machine gun, but isn't experienced in hand-to-hand combat.
Doom Delta v2.5.0 requires GZDoom v4.9.0 or above to run. You will also need a copy of Doom, of course! Either Doom or Doom II will work. You can also take a look at the changelog!
