Hard Doom is a replacement/enhancement mod that replaces all monsters in Doom 2 with versions that are similar in role, but more dangerous. In general, Hard Doom is geared towards players who want a more difficult, genuine survival experience, and it has a variety of visual effects that are more subtle and don't block your view of the action. Over the years since its initial release, it has been meticulously balanced and rebalanced, with new features and effects added to make this a great mod to play through the popular megawads with, without changing Doom's flavor or core gameplay.
This mod requires ZDoom, GZDoom, or Zandronum in order to play!
Improved the weapon functionality of the Sonic Railgun and Skulltag Railgun.
Added a particle effect to bullet & chainsaw puffs.
Lowered the Sonic Railgun's drop rate to 6.25% (from 7.5%).
Increased the spread on the Sonic Railgun's primary fire to 1.8,1.2 (from 1,1) so it's less useful long range.
Added ejected cells to the Skulltag Railgun.
Made railgun shots use sprites instead of particles (requires ZDoom 2.7.0+).
Added a particle effect to rail impacts.
