In the original doom difficulty levels were mostly based on number of monsters and the items that were available in the level. As brad (not me the more important one) has said ultra violence is how doom is meant to be played and my friend put it best as "more things to shoot" though does this remain for the new doom in your opinion?

so I guess my question is outside of the gimmick ultra nightmare mode what are the differences in difficulty levels? Is it more enemies or is it just that their attacks hurt you more unlike the original doom? or is it what new shooters do where it just means enemies do more damage?

Pretty much everything. Demons do more damage, take less damage, there are more of them, and harder versions of the different demon types spawn more often (cyber mancubus spawn more often than regular mancubi, for example). Health and armor pickups give you less, ammo count remains the same. There might be more differences, but that is all I've noticed.

@doctordonkey: AI seems a bit more aggressive too.

much appreciated. I feel bad not playing on ultra violence but didnt want to do it if its just guys take more hits cause thats not fun. Doom harder difficulties mean "more things to shoot" and I think that should be the main focus on the changes.

Though not being able to save when you want hurts it I think

@bradbrains: I'm...actually not sure if enemies take more damage? I made a new save for ultra violence from hurt me plenty and enemies early on seem to take the same amount of damage.

@strangestories: I think the health multiplier of the enemies is still 1 on nightmare. Imps die in one combat shotgun blast up close. Damage of the monsters seems like x3-4. Health and armor pickups is like 60% of the orginal value?

@gundogan: Yeah the main difference is more enemy damage and less health and armor from pickups. Increasing the health would turn enemies into bullet sponges which would slow down the combat, and slowing down the combat is the last thing they probably wanted to do.

@strangestories: that's good to hear . Doom high difficulty was always about having more guys meaning having to figure out crowds better and dealing with ammo. You're right that bullet sponge enemies for all guys wouldn't feel like doom
