Build and Kill Zombies game passes
There are five. They are not the only things that cost Robux: the in-game shop also features Server Luck (2x for 15 minutes, 32 Robux) and a cash packs section, and reviving in the boss fight costs Robux too. But read as a set, they are the clearest statement anyone has made about how this game works, clearer than the game’s own description.

The in-game EXCLUSIVE SHOP: 2x Luck 120, 4x Luck 184, Faster Roll 104, 2x Cash 144. Below the passes a second section starts, headed CASH PACKS.

Two prices for each pass
The store price is what Roblox returns for the pass. The in-game price is what the shop inside the game showed in a recording, and for the first four each one is about a fifth lower. The fifth is the exception: 99 in both places, with [20% OFF] written into its Roblox name. The screen does not say why any of this is, so check your own shop before you buy rather than going by either column.

Three of the five are about rolling
Two of those are permanent luck at different multipliers, so rolling gets more paid support than anything else in the shop. What the rolls themselves hand out is on the luck page, and how many rolls a 1 in 750 takes is worked out beside it.
The fourth names the income
The 2x Cash footnote is the only first-hand statement found about where money comes from: killing zombies and distance travelled, named explicitly because the pass has to say what it multiplies.
The fifth is about looks, and it has a prerequisite
Premium Paint is the newest of the five and belongs with Update 2.5. Its own description says to unlock the paint skill first, and the paint panel in the recording fits: ten swatches are shown, and a greyed strip underneath asks 99 Robux to unlock something more. The strip is not named on screen, so that it is this pass is our reading of the matching price. The skill is a node in the new plot branch of the tree, so the pass has nothing to act on until that node is unlocked. Its description mentions colours and nothing else.

The PAINT panel. Under SELECT A COLOR: are ten swatches in two rows of five. Below them a greyed strip carries a padlock, BUY TO UNLOCK and a Robux price of 99.
