This triggers the final battle of “The Final Reich”: the arrival of the Panzermorder! Its appearance also locks down much of the village and scatters burning wreckage throughout, so you’re locked into Riverside and the village square with the creature.
The Panzermorder takes up enough room that it’s hard to dodge at close to medium range, but it also has a glass jaw. A player with a light machine gun can stun it at range with a single, long burst. The only reason not to keep it permanently knocked down is ammo efficiency.
A player armed with a decent LMG or upgraded rifle should attempt to keep the Panzermorder at bay while the rest of the crew deals with the local zombie population. You can’t kill the Panzermorder through simple gunfire, however. Fortunately, the airship has returned.
Inflict damage on the blimp to make it drop battery packs. After empowering the battery pack by killing zombies near it, just as you did before, stick it onto the Panzermorder when it’s stunned. Doing so drives it away for a few seconds and causes a Taschen Voll power-up to spawn, replenishing your ammo stores.
Stick three powered batteries into the Panzermorder to launch it into the sky, finishing it and the blimp in one fell swoop. You’ve successfully accomplished one major goal, but it’s all downhill from here. There is no escape from the village and the game ends when your team is wiped out. In order to actually survive, you need to find some Easter eggs…
