Ghoul School 3D

Ghoul School, or Ghoul School 3D, is a total conversion for GZDoom/Heretic developed and released by Impie in 2017. It is a 3D remake of Scott Marshall's NES game of the same name, about a high school campus that becomes overrun with a variety of colorful undead monsters. The overall tone of the mod is humorously spooky, and it doesn't take itself too seriously.

Though it is an action game in the tradition of Doom, conversing with NPCs and solving puzzles are both major aspects of the gameplay as well. Often Spike will miss a vital clue or important item if he angers or kills an NPC.

Story
Spike O'Hara just got his dream girl Samantha to agree to go to prom with him, even though it seems she only agreed in order to get back at her ex-boyfriend Frank. With only a week to go before the dance, the school becomes overrun with undead monsters, forcing Spike to venture into the catacombs beneath the school, find the whatever is causing the ghoul uprising, and set things right before the whole town is zombified. The invasion seems to center around the cantankerous vampire Barlow and a weird skull artifact removed from the catacombs by Dr. Femur, the eccentric history teacher.

Weapons
Due to the school campus setting, Spike's arsenal lacks any real firearms: he is forced to be creative and use whatever tools are handy. Some monsters are more vulnerable to one weapon than another: Fire Guys, for example, are easily dispatched with the Water Gun, and immune to the Hairspray Flamethrower.

Baseball Bat. Bashes monsters from a good distance.

Water Gun. A Super Soaker loaded with holy water. Spike's go-to weapon on the campus level, since holy water is harmless to humans but fatal to undead monsters.

Rivet Gun. Rapidly fires painful metal rivets that leave the target sore in the morning.

Hairspray Flamethrower. If Spike finds a lighter he can use hairspray cans as portable flamethrowers which dispense a deadly splash attack.

Mana Zoop. A strange magic spell that allows Spike to shoot monster-piercing ectoplasm from his fingertips.

Artifacts
Spike has access to several stock Heretic powerups, in addition to several new ones, such as the Football Helmet which replaces the Silver Shield.

Ammonia/Bleach Bombs replace the Timebomb of the Ancients as the drop-and-run explosive weapon.

Police Beacon summons up to three policemen which proceed to pummel the nearest monsters with their fists. Like all human NPCs, they become zombies when they are killed, or Fire Guys if killed with fire attacks.

Summon Familiar Scroll summons a small demon that blasts monsters with fireballs. It is a rare and dangerous item: when there are no monsters left to slay, the familiar often gets bored and proceeds to attack human targets.

Morph Cheddar turns targets into rats.

Portable Rejuvinator Unit and its respective refill units can gradually restore Spike's health when activated. If it runs out of juice before a refill is used, the PRU is expended. It can only be acquired from Nurse Ratchet or by cheating.

Crucifix Rosary forces monsters to flee from Spike in fear when it is activated.
