Heretic - Dodging projectiles is easy!
Just dodge the projectiles, they said. It's easier than dealing with hitscan enemies, they said. Well.. they're still right, but you can still manage to screw up sometimes, like I did here! Fun.
MODS USED (All of these shouldn't affect gameplay too much, aside from the first one):
https://github.com/mmaulwurff/idclever-starter (idclever-starter, forces a pistol/wand start in every level - should be compatible with many Doom engine games and mods)
https://forum.zdoom.org/viewtopic.php?t=54992 (SpriteShadow, which gives the enemies Build Engine-style shadows)
https://forum.zdoom.org/viewtopic.php?t=36713 (Heretic Sprite Fixing Project, fixes some minor issues with sprites)
https://forum.zdoom.org/viewtopic.php?t=64299 (Brightmaps plus, adds some lighting to certain textures to make them stand out in peculiar sets of lighting - this version is compatible with the sprite fixes of the above mod)
lights.pk3 (included with GZDoom by default, adds some visual flare to maps)
