https://cdn.discordapp.com/attachments/621773156029300742/961791037297278986/hideous-helmet-bleedpatch.zip Tiny patch that adds cvars for hiding/unhiding the hideous helmet bleed GUI. Made for someone on the discord, but I forgot to ever unload it I guess.
https://cdn.discordapp.com/attachments/621773156029300742/961787395043360828/DmgDirOv_FDA_Necroedit.pk3 My version fixes VM aborts due to nullpointers. No real difference otherwise.
https://forum.zdoom.org/viewtopic.php?t=61369 Adds a cool frame around most HD pickups, and states their names.
https://cdn.discordapp.com/attachments/621773156029300742/961787824498171934/crosshairhp_FDA_HudHelmet_Necroedit.pk3 I swapped the fonts and removed some graphics for this one, and also added hudhelmet support.
https://cdn.discordapp.com/attachments/621773156029300742/961788472627191838/wartrophies-v1.10.2_FDA_HudHelmet_Necroedit.zip I swapped fonts here too, and added helmet support. Same deal as above.
https://forum.zdoom.org/viewtopic.php?f=43&t=61643&p=1068272&hilit=zradar#p1068272 I mostly just use this for it's speedometer, but the other features are also cool.
https://forum.zdoom.org/viewtopic.php?t=60356 I like this for hit confirms, though I didn't edit much about it (yet). Also has hitsounds.
https://forum.zdoom.org/viewtopic.php?f=43&t=71086 Really cool set of weapon/item selector widgets that can save you hotkeys.
https://dastrukar.gitlab.io/hddons-list/#misc:hudeouskminimap-fda I don't have it enabled in the clip, but, this also adds a futuristic automap overlay to your chosen portion of the screen, and can optionally only do so with the helmet worn.
https://dastrukar.gitlab.io/hddons-list/#misc:hudeousdpswidget-fda This is what I used for the targets/dps feed in the top left corner, also comes with helmet option(s).
https://cdn.discordapp.com/attachments/621773156029300742/961789979858718751/immerse-HD_-_FDA_Menudef_Necroedit.pk3 For lean/shifting while moving. All I edited here was the obnoxious customize immerse thing it adds to the main options menu.
https://cdn.discordapp.com/attachments/621773156029300742/961790384516771890/hudeous-levelinfo_FDA_LevelInfo_Necroedit.zip A fork of LevelInfo I never finished, since a lot of it's planned features can be gotten by the debug counters mod Ace maintains right now. This also lists kills/maptime/secrets, and in the current configuration spirit armor/immunity.
https://github.com/dastrukar/hdest-stance_indicator The latest version of Stance Indicator. I used to use my own fork, but most of the features I've added were incorperated into the main mod as of recently.
