The First Room

Every game of Water Park starts at the entrance of the park, the spawn area, before the Hydro Paradise sign and its ticket booths. The guide of rudyspg speaks of a “first buyable door” out of a small plaza that opens on the park, with Up ’n Atoms, the first perk machine of the map, a soul box and benches along the walls. The creator’s Workshop page does not describe the spawn, and no source gives the price of its doors.
The spawn holds most of what the first rounds need. The three parts of the power are usually found there, and the Steam text guides and the guide of Sassy Asi list several spots for each of them inside the spawn; the power itself is built far away, on a shack of the beach. The Mystery Box of other maps is replaced here by the Magic Wheel of Infinite Warfare, which none of the guides places in the spawn.

The power parts
The handle lies on one of the benches of the spawn, the fuse on the barrels next to Up ’n Atoms or on the counter across from it, and the panel by the zombie barrier near the ticket booth. The panel can also lie near Kraken’s Revenge, and the players on Reddit found all three in the spawn in most of their games.

The spawn in round 1
The other side of the spawn in the first round of Sassy Asi: stacks of barrels, jets of water, and a flying saucer over the park beyond.
Up ’n Atoms
The perk machine of the spawn. A Steam text guide calls it Quick Revive, the name of the same perk in Black Ops III.
The soul box
One of the fifteen treasure chests that give the free Thundergun, by the M1 wall weapon, according to Sassy Asi.
The code panel
One of the three number panels that open the gate of the Pack-a-Punch room: the panel of the spawn takes the red number, written on a clipboard by the Cosmic Tunes building.
The Ray Gun Mark II
Once the ten cartoon targets of the map are shot, the Ray Gun Mark II can be bought in the spawn for 10,000 points. One of the targets hangs above the Hydro Paradise sign.
Kendall 44
The starting pistol, named on the HUD of Sassy Asi in round 1. YaBoyBadger finds it very weak.
M1
The wall weapon next to the soul box of the spawn, named by Sassy Asi.
Hailstorm
YaBoyBadger buys the Hailstorm off a wall at the very start of the game, before leaving the spawn after round two; the guide does not say where that wall is.
Enemies
Zombies. The guides read for this book do not describe the first rounds in more detail.
