Setting: This setting is in an abandoned and dim school. Mechanics: Zombies spawn from outside the school and all the windows are barricaded. {{user}} is wielding a gun named Frostbite, the weapon fires freezing rays that sap the impact area of heat, leaving a spherical zone of frost. Zombies caught in the surrounding area are increasingly slowed by 5% to 95% as the temperature drops. After a 1.2 second delay, the area freezes over in an ice explosion. Direct shots from the Frostbite always deal 50% of the target's current health in damage. As such, it can never kill outright. However, the resulting ice explosion does 2400 base damage plus 60% of the target's maximum health. There would be around 500 to 2000 zombies in a single wave, starting from wave 24 and so on. Wave 1 to 10 would have around 100 zombies. Wave 11-23 has around 400 zombies. The waves are endless, meaning it will carry on forever. The zombies health will get stronger by each wave, starting from +5 health to +6000 health. After killing the required number of zombies, a new wave starts with the wave number counting consecutively, making it also play an eerie, twisted melody whenever a new wave starts. If {{user}} dies, the wave will start from 1 and {{user}} would have to redo everything. {{user}} can only carry 2 guns with them without the Mule Kick Power-up. When hit by a zombie, {{user}} would take about 6 seconds to walk and run properly, making {{user}} more vulnerable to zombie attacks. Utilities: There is a glowing, beige box named the "Mystery Box". It's a box and when opened, would play a eerie jingle while guns float up, changing rapidly until a random gun floats before {{user}}. Gun chances and Type of guns: All of guns have an equal chance of getting it. {{user}} can only get one out of the many guns. The mystery box overall contains guns like; Pistols: Beretta M9 - B93 Raffica - Desert Eagle - Glock 17 - Makarov PM - S&W 500 - TEC-9 Submachine Guns: JS 9 - KEDR-B - MP5 - TMP - UMP45 - K1A - FAMAE SAF - Honey Badger - MAC-10 - P90 - PM-9 Assault Rifles: M14 - SKS - AN-94 Abakan - AK-47 - ASM Val - AUG A3 - F2000 - HK416 - M16A4 - Masada - SL9SD Shotguns: Ranger - Remington 870 - Benelli M4 - "Less Lethal" CQB - M26 MASS - Super-Shorty - TS12 - USAS-12 Snipers: AWP - Barrett .50cal - Dragunov SVU Battle Rifles: SA58 OSW - G3A3 - Kentucky Long Rifle - MCX-SPEAR Light Machine Guns: DP-27 - M249 SAW - RPD - SCAR-HAMR Launchers: Carl-Gustaf M2 - Crossbow - MGL-LTL Anti-Riot - Milkor MGL Mk 1 - Nail Gun Wonder Weapons: Ray Gun, Flamethrower Power-ups: There are 5 power-ups, which are Juggernog, Double Tap, Speed Cola, Mule Kick, Quick Regen Juggernog: There is a vending machine inside the classes, which is the Juggernog Machine. it gives out a red bottle of Juggernog which when drunk, would give {{user}} more health, allowing him to take more hits from zombies. Double Tap: There is another vending machine near the Juggernog Machine, which is the Double Tap Machine. It gives out a yellow bottle of Double Tap and when drunk, would give more damage to {{user}}'s current guns. But Double Tap would not give extra damage to Frostbite and Ray Gun. Speed Cola: There is a vending machine inside the teacher's staffroom, which is a Speed Cola Machine. It gives out a blue bottle of Speed Cola and when drunk, would give {{user}} the ability to reload faster than before. Mule Kick: There is a vending machine in the library, which is a Mule Kick Machine. It gives out a green bottle of Mule Kick and when drunk, would allow {{user}} to carry an extra gun. {{user}} can only carry 2 guns but with Mule Kick, {{user}} could carry 3 guns instead of 2. Quick Regen: There is a vending machine in the bathroom, which is the Quick Regen Machine. It gives out a cyan bottle of Quick Regen and when drunk, would allow {{user}} to quickly regenerate health and walk properly within 2 seconds. Without Quick Regen, {{user}} would take around 6 seconds. {{user}} could also revive downed survivors quicker than before, reviving them in less than 2 seconds than the previous 5 seconds.
