The First Room

On ZFRR, the First Room of Gröesten Haus is the whole farmhouse. The map has no door to buy: the players spawn on the ground floor, in front of the front door, and can walk both floors and both staircases from the first wave. The only room that stays closed is the secret Mystery Box room upstairs, which the leaderboard does not allow to open. Each player starts with the weapon, the Special and the mods of their own Zombies loadout, and the shovel.
The MP-40 hangs straight ahead of the spawn. To the left, a staircase climbs to the first floor; to the right, two doorways on either side of a fireplace lead to the kitchen, the right-hand one through a small side room with the STG44 and the Geistschild machine. The second staircase climbs from the kitchen to the Combat Shotgun, and a hallway upstairs links the two staircases past the Random Blitz and the doors of the secret room.
MP-40
1,000 Jolts, a submachine gun, in the weapon locker straight ahead of the spawn.
STG44
1,500 Jolts, an assault rifle, in the small side room by the fireplace, next to the Geistschild.
Combat Shotgun
1,000 Jolts, a pump-action shotgun, upstairs, at the top of the kitchen staircase.
Those three weapon lockers are the only weapons for sale. Without the secret room there is no Mystery Box, so a First Room game is played with them, the starting weapon and the power-ups.
Geistschild
500 Jolts for the first charge, then more after each purchase, up to 10,000. The only armor machine of the house, in the small side room of the ground floor, to the left of the STG44. Each charge absorbs one hit that would have downed the player, three charges at most.
Random Blitz
2,000 Jolts, upstairs, in the hallway between the two staircases. It grants one Blitz drawn at random, then needs about two minutes before it can be used again. There is no other Blitz machine on the map, so Lebenblitz only comes from it.
The secret room
Next to the Random Blitz, behind two closed doors. It holds the only Mystery Box of the map and opens once ten hidden lanterns have been shot. On this leaderboard it stays shut.
The kitchen
Through the doorway to the left of the fireplace: the dining table and the second staircase. Two of the ten lanterns hang here.
No door to buy
The house has no door, debris or barrier for sale: from wave 1, the players can use both floors and both staircases.
The enemies
Ordinary zombies. Wüstlings join them from wave 10, and a single Brenner arrives on wave 50.
The Gröesten Haus leaderboard keeps separate boards for solo and for two, three and four players. Its rules:
Doors closed
Reach the highest wave you can without opening any door or barrier. Opening the Mystery Box room is not allowed.
Two categories
No Consumables, the reference board, where consumables are not allowed, and With Consumables. Both take solo, two, three and four players.
Full waves
Every wave must be played in full. Glitches and exploits are not allowed, and so is going down on purpose to block the zombies‘ path.
Video
The whole game must be recorded and the lobby shown before the map is launched. In No Consumables, every player of a co-op game must record their own point of view.
Where to post it
A Twitch video must be saved as a highlight, since past broadcasts are not accepted; a YouTube video must be public or unlisted.
