Project MSX is a weapons and gameplay mod that brings some elements of modern FPS into your 16 year old Doom, and with this attempting to merge both new-school and old-school styles of FPS gameplay.
''No infighting'' means enemies wont attack each other. Enemies also wont hurt each other even with attacks with splash radius. This ''No infighting'' version is made to make the game more difficult, since enemies won't get distracted nor they will killl each other anymore. This mod is the same as ''projectMSXEnemiesonly'' but it includes extra monsters from the ''Extra Badass Monster Pack for Project MSX'' made by VICE. I had to modify code from both mods to make it compatible. Mod Loading Order: projectMSXEnemiesonly_edit_v2_NOINFIGHTING.pk3 + projectMSXEnemiesonly_extramonsterscompatibility_v1_NOINFIGHTING.pk3 + (Insert any other mod here) Tested on LzDoom. I think it works fine on Zandronum too. Don't forget to extract the 2 pk3 files inside the rar file.
