Blitz Machines are a triumph of necro-science. If not for the subsequent death and unholy resurrection of most of the personnel involved, they would have become a cornerstone of the German war effort. You can find Blitz Machines in several locations throughout the village, ready to provide upgrades in exchange for a significant number of Jolts. A Blitz provides a powerful, permanent, and passive bonus.
By default, a single character can hold and benefit from four Blitzes (five, if you take the Hoarder Mod). Newly acquired Blitzes will overwrite the oldest ones and you can’t take a single Blitz more than once. However, if you’re incapacitated by damage, you run the risk of losing your Blitzes. If you bleed out, you gradually approach a point where your Blitzes vanish one by one.
While paying into a Blitz Machine, you become vulnerable for a few seconds as your character receives the upgrade. Just remember that you are locked in an animation while receiving the blitz, so it’s not possible to find cover for safety.
Geistchild
COST: 500
EFFECT: EACH HIT OF GEISTCHILD NEGATES ONE LETHAL INCOMING ATTACK THAT WOULD OTHERWISE HAVE KILLED YOU, AT THE COST OF THE GEISTCHILD.
Your current amount of Geistchild is represented by up to three gray shield icons on your character portrait.
It’s always important to have Geistchild but, at best, it’s a stay of execution. Geistchild gets destroyed quickly if you get cornered or surrounded. It’s a last shot at survival, not a security blanket.
Every time you purchase Geistchild from a Geistchild machine, its cost increases by 500. Acquiring Geistchild via other means, such as the Geistchilded Up or Bolster Morale Mods, doesn’t affect the cost.
Faustblitz
COST: 2000
EFFECT: DEAL MORE DAMAGE IN MELEE.
If you want to be a shovel ninja, then take this along with all the melee-influencing mods you can find. With this blitz, the shovel will one-hit kill all non-special zombies until round 16 is reached.
Kugelblitz
COST: 2000
EFFECT: DOUBLES THE RATE OF FIRE, WHICH ALSO DOUBLES WEAPON DAMAGE.
Kugelblitz isn’t a massive improvement, but it’s quite noticeable. By the time you reach the later waves of enemies, you want every advantage possible. Fortunately, it’s also one of the easiest Blitzes to find.
Laufenblitz
COST: 2000
EFFECT: MOVE 7% FASTER BY DEFAULT AND YOUR STAMINA NO LONGER DEPLETES WHILE SPRINTING.
Much like Kugelblitz, Laufenblitz’s effects are a bit subtle, but it’s worth taking for any character regardless of his or her intended role. Sooner or later, you’re always going to end up running for your life!
Lebenblitz
COST: 500/1500
EFFECT: IF PLAYING SOLO, YOUR CHARACTER AUTO-REVIVES UP TO THREE TIMES BEFORE THE BLITZ RUNS OUT. IN A GROUP, YOU REVIVE FALLEN TEAMMATES ROUGHLY TWICE AS FAST.
This Blitz Machine is in the starting area, so it’s worth acquiring early on just to be safe. You may want to ditch it unless you’re a Medic, as better Blitzes become available. This blitz must be reacquired once the self-resurrection is used. It can be bought a maximum of three times.
Schildblitz
COST: 2000
EFFECT: WHEN YOU RELOAD, YOUR CHARACTER EMITS A SHORT-RANGE JOLT OF ELECTRICITY THAT STUNS AND DAMAGES ZOMBIES CAUGHT IN IT.
The radius of the shock attack depends on the percentage of ammo remaining in the clip when reloading. Reloading an empty clip emits a shock at full range. Reloading a large clip with only a single shot missing will result in a minimal sized shock. There is also a three second cooldown.
Schnellblitz
COST: 3000
EFFECT: RELOAD TIME IS CUT IN HALF.
This is an absolute lifesaver and should be near the top of the priority list for all characters once you unlock its location.
