Shoot Haus:
Easter Egg

The flare gun

The flare gun is a step of its own, done in the Zeppelin once the Pack-a-Punch is open:

1. Pick up the first punch card in the Engine Room of the Zeppelin. It lies on one of four wooden crates, around the paths to the Pack-a-Punch.
2. For the second, find the valve that lets out steam, with a faint hiss, and shoot it with a Pack-a-Punched weapon: the steam moves to another valve. Keep shooting the steaming valve until the steam comes out of the valve above the exit hatch. The order is random each time.
3. Press the button of the Payload Bay to release the pressure: the second card falls on a crate of the Bombed Street, near the spawn.
4. Place the two cards in the two terminals on each side of the armoured door, on the lower floor of the Engine Room, and start the lockdown with the button upstairs.
5. Survive while the door slowly opens. RAPS and a Panzer Soldat join the zombies. Once the door is open, a Max Ammo drops and the flare gun can be taken.

Step 1: the fuses

1. First fuse: after the first RAPS round, the RAPS power-up joins the cycle of power-ups. Pick it up, jump over the wall of the Element 115 Defense next to the shield bench, roll through the narrow gap on the left and blow up under the tree with the blue mist at the end. The fuse falls on a crate of the spawn.
2. Second fuse: shoot it off the pipe in the exit hatch of the Zeppelin with a Pack-a-Punched weapon. It falls into the map.
3. Shoot the large 115 rock of the Element 115 Defense with the Voltgewehr: a sound plays. Flapix shoots it three times. Sassy Asi also shoots an antenna on the building behind the generator with a Pack-a-Punched weapon.
4. Kill zombies with the Voltgewehr, stunning them and finishing them with another weapon so they explode, until the same sound plays again.
5. Blue mist now rises from one of the puddles of the map; Flapix counts five puddles. Explode a zombie in the mist the same way: a blue dome forms. Stay inside and kill zombies until it fades. Another puddle then smokes. Do it three times; hcufo gets a Max Ammo after each dome.
6. Shoot a dig site with the Voltgewehr and dig it with the golden shovel: the second fuse comes out.
7. Place the two fuses in the fuse box of the Zeppelin, on the lower floor of the Engine Room, near the door of the flare gun.

Step 3: the lights and the vials

1. One of the eight small lights around the door of the flare gun sparks blue. Shoot it with a Pack-a-Punched weapon: the spark jumps to another one. Shoot each sparking light in turn, fast; too slow, and the spark goes back to the first, in the same order.
2. Once the eight are done, a crate of vials falls from the exit of the Zeppelin. Three blue vials are now spread on the map; each one makes a sound when a player is close.
3. Pick them up in the right order. A wrong vial breaks with a sound of glass and costs a magazine. Sassy Asi gives the order lowest sound, highest, then middle; Flapix says the order is random but stays the same for the whole game.
4. Bring the vials to the three soul boxes of the Zeppelin: one near the hatch, one on the stairs upstairs, one to the left of the door of the flare gun. Turn one on, kill zombies around it until it is electrified, place a vial on it and shoot the vial to break it. Do the same with the other two.

Step 4: the key and the cockpit

1. Pack-a-Punch a weapon that is already upgraded: 6,000 points at this step, for Flapix and hcufo. A key falls to the ground in front of the machine.
2. Open the gate next to the exit of the Zeppelin with the key and follow the walkway down to the cockpit door. It opens slowly; Flapix survives until it is open.
3. Interact with the controls, twice according to Flapix, to go “full steam ahead”: this starts the boss fight. Sassy Asi warns that it can take a moment before the controls answer, and that it cannot start during a RAPS round.

The cockpit

The controls of the Zeppelin. The prompt warns: “full steam ahead [POINT OF NO RETURN]”.

Step 5: the Panzer Soldats

1. Go back to the Pack-a-Punch: an invincible Panzer Soldat appears.
2. Stand by one of the three soul boxes, which is electrified, and let the Panzer fire one of its electric projectiles at it. A blue dome forms for a few seconds: inside it, the Panzer can be hurt.
3. When the dome fades, the machine needs to recharge: move to another one and do the same until the Panzer dies.
4. The Zeppelin crashes. At the crash site, two more invincible Panzers come. Beat them the same way, with the three machines of the crash site: one under a walkway, one left of the Pack-a-Punch and one at the top, across from it.
5. Once both are dead, the quest is over: every perk is given, and the jump pad leads back to the map.

The change notes of June 2024 make the boss Panzers take less damage early in both fights and more as the fight goes on, so that they cannot be killed in one burst; since March 2024 Double Tap II gives them 15% resistance to bullets.
