Build and Kill Zombies

Build a car, bolt weapons and defenses onto it, and see how far it survives. This site answers the two things people actually arrive asking — which codes are real, and whether they are too late for the event — and it shows its working.

These are a snapshot taken when the site was last built, not a live feed. The boss figure is the count of players holding Roblox’s badge for beating it, divided by the most widely held badge in the game — we show the other two ways of counting it, because Roblox’s own page gives a different number.

Why the code lists contradict each other

There were two batches. An earlier set of strings stopped working, one publisher reported that, and the quote spread — but by then a second batch had appeared. Most lists blend the two. We keep them apart.

The boss is tied to a limited event

Roblox’s badge for beating King 1x1x1x1 calls it the “Hacker Event Great Boss”. The event has a published end time, and nobody has said what happens to the fight afterwards. What we know.
