01 What a merge needs
Two crew of the same rarity, both at level 40, merge in the bedroom into one crew
of the next rarity. The merge consumes one prestige item and destroys both parents.
It needs the Prestige research: laboratory 8, 3000 research points, eight days.
02 The outcome is random, and that is the whole mechanic
The game lists every pair of a rarity as a valid recipe, a crew paired with a second
copy of itself included, and the pool of outcomes is identical for all of them. Which crew
comes out does not depend on which two went in. This is the reverse of Pixel Starships 1,
where prestige was deterministic and a calculator could tell you what to cross to reach
a named crew. In Pixel Starships 2 no such calculator can exist.
03 The odds are assumed, not published
The game gives no weights for the pool, so every outcome here is assumed equally likely.
Every merge count on this page follows from that assumption and from nothing else.
04 Stars, and where the rule comes from
Stars belong to the crew you own rather than to the crew design, so they are
not in game data at all. The rule used here is a developer answer on Discord: the child
takes the average of its parents, rounded down. Two identical crew stay separate instances
and never stack into an extra star. A rarity holds as many stars as its place in the ladder,
so a Unique holds three and an Epic four; the six-star ceiling for Legendary follows
the ladder and is not verified in game.
05 Stars only go down
A parent can never hold more stars than its own rarity allows, and the child's ceiling
sits one higher. A Legendary merged from two five-star Heroes therefore lands at five
of six. Prestige never adds a star to a line; only a draw can.
06 Why the ladder starts at Unique
Every input has to reach level 40 first, and nobody spends that on Common or Elite crew.
The step below is thinner than it looks anyway: the item called Elite Prestige says it merges
two Common crew, yet the game returns no recipes for that step. So this page makes no claim
either way about whether a Common or an Elite crew can be produced by prestige, and the list
of crew that prestige cannot give you covers Unique and above only.
07 Some crew never come out of a merge
The crew below are of a rarity that prestige produces, yet no outcome pool holds them:
a merge cannot give them at all, and only a draw or an event can. The pools change with
the game, so this list follows the recipes the game returns today.
Unique: Boarder Droid III, Conductor, Defender Droid III, Mini Droid III, Service Droid III, Singularity Lv3
Epic: Boarder Droid IV, Defender Droid IV, Jiang She, Jiang Shi, Service Droid IV, Singularity Lv4
Hero: Aquarius, Aries, Big Boom Cat, Boarder Droid V, Cancer, Capricorn, Defender Droid V, Gemini, Leo, Pisces, Red Baron, Sagittarius, Scorpio, Service Droid V, Singularity Lv5, Taurus, Virgo
Common and Elite are absent from this list on purpose: the game has no recipes for the step
that would produce them.
08 Where the gas figures come from
One crew costs 28 820 000 gas to climb from level 1 to 40 with no research
discount, October 22, 2026 data. The merge counts multiply that figure.
Research discounts on crew levels are not applied, and the prestige items themselves are not
priced here.
09 Prestige fragments and days
Gene Harvesting on Vespera drops six prestige fragments, each with its own chance
per run: 90% Common down to 3% Legendary. A run takes 3h 30m and one drone works one
operation, so a day holds at most about 6.9 runs. DAYS counts that pace with no pauses,
which is why it is an average and not a deadline: at 3% the ninth Legendary fragment
can take far longer than 43.8 days. A run rolls every fragment at once, so a set of
several rarities takes as long as its slowest rarity, not the sum of them. Nine
fragments make one item, and that nine comes from the recipe in the game catalog.
Mining a rarity directly is always cheaper than merging up: a step up costs nine items
of the rarity below, that is 81 of its fragments, against nine of its own.
