Water Park: Weapons

Wall weapons

Water Park carries the weapons of Infinite Warfare, ported by TheSkyeLord and ProRevenge among others, according to the Workshop page. The page does not list them, and the guides read for this book name only a few wall weapons; no source gives their prices.

M1

In the spawn, by the soul box, according to Sassy Asi.

Hailstorm

Bought off a wall by YaBoyBadger at the start of the game, in place of the starting pistol; good until about round seven in that guide’s words.

VPR

On a wall of the Journey into Space area, next to a perk machine. YaBoyBadger calls it extremely good, Pack-a-Punches it for the escort of David Hasselhoff and buys its ammo on the wall during the boss fight.

Thermite

A Reddit thread finds no grenade on the walls other than thermite, whose kills do not count for the grenade challenge of N.3.1.L.

The Magic Wheel

The Mystery Box gives way to the Magic Wheel of Infinite Warfare, made by GCPeinhardt according to the Workshop page. The players on Reddit, who call it the box, got a grenade launcher and monkey bombs from it, both counted for the grenade challenge. YaBoyBadger got the UDM from a shovel, not from the wheel. In the footage of Sassy Asi, a Magic Wheel stands in front of the Journey into Space building.

The water guns

The four zappers of Zombies in Spaceland, made by GCPeinhardt, are the water guns of the park. They come from the four souvenir machines, each machine giving its own gun.

A souvenir station

A souvenir machine, under its glowing sign, with the prompt to fill the zapper with coolant.

Put the three coins of N.3.1.L into a souvenir machine. They are won during the main quest, one after each challenge.
Take the bucket that N.3.1.L gives with the third coin.
Fill it with the glowing coolant at the beach, where David Hasselhoff walks into the water.
Run to the souvenir machine before the bucket overheats: it sets its carrier on fire. A dip in any pool of the park cools it down.

Gun	Souvenir machine	Route from the beach
Face Melter	Up the right side of the slide of the Change Chews area	Toward Change Chews, with a stop in the pool at the bottom of the slide
Dischord	Up the stairs on the left of Kraken’s Revenge	Toward Change Chews, then its portal to Kraken’s Revenge
Shredder	On the bridge that leads to the teleporter	The portal right behind the coolant, to the slide near Cone Lord, then through the tables
Head Cutter	At the end of the bridge on the right, up the hill in front of Racin’ Stripes	Right through the tunnel, with a stop in the water by Racin’ Stripes

The routes are those of Sassy Asi. YaBoyBadger prefers the Dischord, which fills the boss portal with souls “unbelievably easy”, and finds that the water guns break the weak points of the boss in two shots.

Thundergun and Ray Gun Mark II

Thundergun

A reward of the fifteen soul boxes of the park, waiting in the in-between area of the teleporter of the Pack-a-Punch.

Ray Gun Mark II

Sold for 10,000 points in the spawn once the ten cartoon targets of the park are shot.

Where to find the soul boxes and the targets

The shield

The shield of the map, built at the Pack-a-Punch from a wheel, a hose and a surfboard, is described on the page of the buildables.
