Developed by id Software, and originally released in 1993, DOOM pioneered and popularized the first-person shooter, setting a standard for all FPS games. The critically acclaimed sequel, DOOM II, followed in 1994. Now the definitive, newly enhanced versions of DOOM + DOOM II are available as a combined product.

Original Release - December 10th, 1993 & May 5th, 1994
Enhanced Release - August 8th, 2024

DOOM
You are Doomguy. A Space Marine tasked with surviving and fighting off the hordes of Hell after the UAC (Union Aerospace Corporation) opened a portal to their dimension allowing Demons to flood Mars and eventually Earth. It's up to Doomguy to Rip and Tear... through the hordes of hell...until it is done.

DOOM 2
Hell has invaded Earth, and to save it, you must battle mightier demons with even more powerful weapons. This beloved sequel to the groundbreaking DOOM (1993) introduced players to the brutal Super Shotgun, the infamous Icon of Sin boss, and more intense FPS action.

TNT: Evilution 
The UAC relocated their experiments to one of the moons of Jupiter. A spaceship, mistaken for a supply vessel, was granted access. But when it got close to the base, demons poured out. All your comrades were slaughtered or zombified. This time it's not about survival. It's about revenge. 

The Plutonia Experiment
Every effort has been made by the nation's top scientists to close the seven interdimensional Gates of Hell, but one portal remains open. Alone, you must infiltrate the ravaged base, defeat the demon Gatekeeper, and seal the last Hell portal before the undead take over the world. 

Master Levels for DOOM II
This expansion includes twenty additional levels, all with the same hell-spawned horrors and action of the base game. Each level was created by independent designers and supervised by id Software.

Sigil
Created by id Software co-founder, John Romero, and released as an episode-sized mod consisting of 18 new maps, Sigil fits in between the timelines of DOOM (1993) and DOOM II. Baphomet, the gatekeeper of Hell, “glitched the final teleporter with his hidden sigil, whose eldritch power brings you to even darker shores of Hell. You fight through this stygian pocket of evil to confront the ultimate harbingers of Satan, then finally return to become Earth’s savior.”

Legacy of Rust
Created in collaboration by id Software, Nightdive Studios, and MachineGames, Legacy of Rust is the newest episode for DOOM, and the first official episode since DOOM II to feature new demons and weapons. This 16-map Episode is broken up into two 8 map sections: The Vulcan Abyss and Counterfeit Eden.

30 Years ago on December 10th, 1993 gaming and first person shooters would change forever with IdSoftware's critically acclaimed DOOM. Since then we've recieved big hitters such as Quake and Half-Life that paved the way for FPS and gaming as a whole.

In DOOM 1+2 there's plenty of secrets that can give you extra health, items or early weapons if found. This is all of the ones i found or are public knowledge

EPISODE 1 - KNEE DEEP IN THE DEAD

E1M1
The first secret is in the room after the first two enemies. You'll see an Imp standing above the acid pit. That is a door that will open once you progress to the final room and come back. You'll get the shotgun. A 2nd area that isn't necessarily secret is the outside room that can be entered from a door on the right side in that same room with the acid floor.

E1M2
In a small crevice in a hallway there's a door that can be opened that leads to a pretty dark room. If you follow the right side until you have a few turns you'll come to an outside area where the chainsaw can be found early



EPISODE 2 - SHORES OF HELL

EPISODE 3 - INFERNO

EPISODE 4 - THY FLESH CONSUMED

EPISODE 1 - THE SPACE STATION

EPISODE 2 - THE CITY

EPISODE 3 - HELL

A few things to note before we begin

Total of 33 Achievements in DOOM 1+2
Some are secret and some are story based so you'll get them no matter what
Cheats DO NOT disable Achievements
You can select any level from the main menu so achievements will still work.
Some achievements can be slightly bugged but still obtainable
