A small update has been released for our modern DOOM and DOOM II ports today. The only change is a fix for FPS dependent mouse sensitivity. Your sensitivity will feel different for the same slider value compared to before, however it will now feel more consistent, especially at higher framerates when vertical sync is disabled.

The unmodified, original DOS version running under DOSBox is still available! When launching the game, select "Launch DOS version" and you will have access to the previous version.


Anyone who already owns either The Ultimate DOOM or DOOM II: Hell On Earth on Steam will automatically receive the new re-releases in their libraries. The original DOS versions are still available as a separate launch option from within Steam, and the original DOS IWAD files are in their original location on disk. Please note: if you have modified the files in the Steam install folder directly, some files may be overwritten. You should not modify files in the Steam folder directly, as this may cause issues. Anyone who purchases Steam copies of DOOM or DOOM II: Hell On Earth in the future; it will default to the re-releases but can access the original DOS versions as a separate launch option from within Steam.


For the first time in an official port, the original DOOM renderer has been modified to natively render 16:9 without any letterboxing. The FOV has been increased to reveal more image on the side instead of chopping off the top and bottom. All new 16:9 versions of the titlescreen, intermission, and ending screens have been added. Many of our Add-Ons have also had widescreen support added, so download the latest version from the Add-Ons listing to check it out!


The engine now can load DeHackEd patches, a popular tool for the original release that modified the game in order to support more advanced behavior. Add-Ons can now use new weapons, change enemy behavior, and more!


Split screen deathmatch has been changed to what is commonly known in the community as "Deathmatch 3.0." Weapons will stay in the world after being picked up in order to account for the extreme lethality of DOOM's weapons, and the weakness of the starting pistol, while all items and ammo respawn on a 30 second timer. Invulnerability and Invisibility will never respawn after being picked up for the first time.


A crosshair, which can be disabled in Gameplay Options, will also change colors when targeting an enemy. This means less guessing if firing a rocket is going to aim at the enemy above you, or fire directly into your face, bringing about an untimely death. Enabling the crosshair may also help reduce motion sickness by giving you a fixed point to focus on.


Gyro Aim, enabled by default when a DualShock 4 controller is plugged in, allows you to look left and right by either turning the controller, or rolling the controller left or right. This allows for an additional amount of precision by enabling fine corrections to turning in order to track moving enemies, while still using the right analog stick for large turning movements. Gyro Aim can be set to either use the controller's yaw, or pitch, or disabled entirely, along with a separate sensitivity slider.


You can set the FPS limiter inside Video Options to 30, 60, 120, 144, 165, 240, and unlimited FPS.


A millisecond accurate timer has been added to the minimap, and to the end of level intermission, for anyone looking to speedrun levels.


iddqd, idkfa, idclip, and all of their friends can now be entered from the keyboard, in addition to the Cheats menu, as in the original 1993 release.


A message and notification is now displayed when you enter into a secret area for the first time.


Ultra-Violence+ is a twist on our existing Ultra-Violence skill level. Deathmatch/Co-op only weapons will spawn in, and enemies are fast like in Nightmare mode. In DOOM II, this means you get the BFG and Rocket Launcher right from the start, but in Final DOOM: Plutonia you'll have a Spider Mastermind staring you down as soon as you spawn in on the first level. It cuts both ways.

• Nightmare behavior has been fully restored to the original 1993 release by making enemies move twice as fast.
  
• In honor of double speed enemies returning, the warning when selecting Nightmare difficulty has been restored.
  
• Resolved an issue where lighting in split screen was not accurate compared to single player.
