Astral Ascent x Expedition 33: Everything in the Crossover

Astral Ascent just pulled off a crossover almost nobody saw coming: the reigning Game of the Year, Clair Obscur: Expedition 33, has officially joined the roguelite in a free update out now. This GameMarket.gg breakdown covers everything the "For Those Who Come After" update adds, from the Expedition allies who fight at your side to the new bosses and stages pulled straight from Expedition 33's world. The hook writes itself: Gustave, Maelle, and Sciel stepping into a fast-paced action roguelite is either a dream team-up or a stretch, and the only way to judge is to look at what actually made it in. Spoiler: there is a lot here, and most of it fits better than you would expect.

What the crossover update is

The headline is that this is a free collaboration update called "For Those Who Come After," released on October 8, 2026 by developer Hibernian Workshop. There is no paid DLC or season pass attached, so every Astral Ascent owner gets the full crossover at no extra cost. For a collaboration with the most awarded game in recent memory, giving it away free is a genuinely generous move.

There is one condition to unlocking it, though. The crossover content is gated behind beating the main game on Destiny Level 0, meaning you need to have finished Astral Ascent's core campaign before the Expedition 33 material opens up. That keeps the collaboration as a reward for invested players rather than something dropped on brand-new accounts, which fits a roguelite built around long-term progression. Astral Ascent itself is available on PS5, PS4, Switch, and PC through Steam, Epic Games Store, and GOG, so the update reaches players on nearly every platform.

Why this pairing works better than it looks comes down to pedigree. Expedition 33 is the turn-based RPG that swept The Game Awards 2025 and became the most awarded game in the show's history, while Astral Ascent is a slick, content-rich action roguelite with a devoted following. Both are celebrated creations from the French indie scene, so rather than a random cash-in, this reads like two respected studios genuinely celebrating each other's work.

For anyone who has never played it, Astral Ascent is a fast, side-scrolling action roguelite built around flashy spell-based combat. You play as heroes imprisoned in a world called the Garden, battling through randomized rooms and powerful Zodiac bosses while stacking spells, upgrades, and synergies into a different build every run. That endlessly replayable loop of mixing and matching powers is exactly the kind of structure that makes dropping in a whole new set of summonable allies feel natural rather than bolted on.

The Expedition allies who join the fight

The centerpiece of the update is that the cast of Expedition 33 shows up to fight alongside you, and this is the part the teaser leans on hardest. Rather than being full playable characters, they arrive as Expedition ally summons you recruit one at a time per run at a new Campfire, each bringing a distinct combat role lifted from their RPG personalities. Picking which ally to run with becomes a fresh strategic layer on top of Astral Ascent's existing builds.

The three faces front and center on every promo are exactly who you would expect, and each plays to type:

• Gustave: a supportive powerhouse who heals you, boosts your attack, strikes alongside you, and charges up a powerful finisher.
• Maelle: a stance fighter who shifts based on your current HP, rewarding you with a strong attack when you hold a stance long enough.
• Sciel: a card-drawing specialist whose Moon grants mana, Sun deals direct damage, and Twilight lands a huge hit.

They are not alone, either. The update rounds out the roster with three more Expedition allies in Lune, Verso, and Monoco, so there are six summons in total to experiment with. Lune casts elemental spells that match your build, Verso grows stronger the more hits he lands without taking damage, and Monoco draws random cards that each trigger a different monster summon. That variety means your choice of ally can completely reshape how a run feels, which is exactly the kind of depth roguelite players crave.

New bosses and Expedition 33 stages

A crossover this size is not just about allies, and the update brings a real chunk of Expedition 33's world into the game. On the challenge side, it adds three new bosses dropped into the Prison, each with its own gimmick. Golgra starts calm before her kicks and gestral allies turn brutal in a second phase, The Mime forces you to defeat two targets together or watch them revive each other, and Petank chains running, projectiles, clones, and explosions into a chaotic fight.

The collaboration also reshapes the map with locations fans of the RPG will instantly recognize. The update folds in three new stages pulled from Expedition 33: Lumière, the Gestral Village, and the Campfire, weaving the look and feel of the award-winning game directly into Astral Ascent's run structure. For anyone who played Expedition 33, running through these familiar places in a completely different genre is a real novelty.

How it all slots into a run is clever. Before the world-ending final boss, one of these new areas appears at random, and you choose between the Clair Obscur content or the usual Andromeda Bar, with that choice locked for the rest of the run. That design keeps the crossover feeling like an organic part of the roguelite loop rather than a separate side mode, and it gives you a reason to weigh the new content against the familiar every single run. A new in-game menu also tracks exactly what you have unlocked and what is left to find.

Dream collab, or a stretch?

So which is it, the dream team-up or the forced mash-up the hook is teasing? The honest read leans heavily toward dream collab, because the update does not just slap Expedition 33 logos onto existing content. The allies are built to reflect how each character actually fights in their home game, the bosses have unique mechanics, and the stages are faithful recreations rather than reskins, which is the difference between fan service done with care and a lazy tie-in.

The pairing also makes sense on a creative level. Both games come from the celebrated French indie scene and share a love of stylish combat, striking art, and rewarding depth, so Expedition 33's characters feel at home in Astral Ascent's world instead of clashing with it. When two studios clearly respect each other's work, the result tends to feel earned, and that is the vibe this collaboration gives off.

If there is any catch, it is simply that the two games play nothing alike, since one is a measured turn-based RPG and the other is a fast, reflex-driven roguelite. But the update embraces that contrast rather than fighting it, reimagining the Expedition cast for a new kind of combat, and that reinvention is a big part of the appeal. Seeing how a beloved RPG hero translates into frantic roguelite action is exactly the kind of surprise that makes crossovers fun.

Should you jump in?

For existing Astral Ascent players, this is an effortless recommendation, since it is free, it adds hours of new content, and it celebrates one of the most acclaimed games of the era. If you have already cleared the main campaign, the Expedition 33 material is waiting for you right now, and if you have not, it doubles as a strong reason to finally push through and beat the game.

If you are an Expedition 33 fan who has never touched Astral Ascent, this crossover is a surprisingly good entry point into the roguelite genre. Getting to fight alongside Gustave, Maelle, and the rest in a brand-new style is a novel way to spend more time with characters you already love, and Astral Ascent's polish makes it an easy game to fall for on its own merits.

Either way, "For Those Who Come After" answers its own question with confidence. The reigning Game of the Year slotting into a roguelite could have felt forced, but the care poured into the allies, bosses, and stages makes it land as a genuine celebration of both games. The best way to settle the dream-or-stretch debate for yourself is to load up a run, recruit an Expedition ally, and see how it feels when two very different worlds collide.

If you want to dive into the crossover with a head start, you can pick up a ready-to-go Astral Ascent account or save time clearing the main game to unlock the collaboration with reliable Astral Ascent hourly services.
