High Octane Nightmare Fuel
Human Sacrifice: Ranulf witnesses a man dying being dropped from a cage into a well, filled with acid.
Immune to Bullets: The scientists experiments that can only be killed by fire or magic. Also, Cthulhu.
Invisible Monsters: the Spawn of Yog-sothoth.
Jump Scare: Most of them in The Ghoul´s Lair. The caves are small and narrow with sharp turns, so you might often end up in front of one of the Ghouls.
Justified Tutorial: Since most people should already know about moving and firing in a gold source game, the hazard course simply consists of visiting Sir Henry. Then he explains how the powers of the spellbooks work.
Kill It with Fire: Father Dagon, and some other enemies, are weak against fire.
Laser Hallway: Ranulf wanders into one in Yith. Fortunately, there is a grid on the floor that he jumps through, surviving the trap.
Life Drain: The Spellbook of the name Drain Life can do just that from human enemies.
Loads and Loads of Loading: The maps are smaller than the usual, which means then leaving an area might load again and again. Thankfully, they are still only a few seconds long, as in most Half-life mods.
Lovecraft Country
Molotov Cocktail: One of the useful weapons obtained.
