Introduction
I’ve been revisiting Kirby and the Forgotten Land + Star-Crossed World and the package feels like a smart “second draft” of 2022’s breakout 3D Kirby—cleaner visuals, tighter routes, and a finale that actually tests your dodge timing. The Switch 2 upgrade folds in a new side story while polishing performance, so the cheerful surface hides a surprisingly technical platformer underneath.
What Star-Crossed World Actually Adds
Nintendo’s Switch 2 Edition + Star-Crossed World bundles the original game with a paid upgrade that’s exclusive to Switch 2. You get higher resolution, smoother frame-rate, quicker loads, and a fresh side story layered into remixed stages—complete with new Mouthful Mode twists and collectible “Starries.” Reviews also call out an expanded Colosseum capstone (Ultimate Cup Z EX) for veterans.
Fast Facts
- Platform: Nintendo Switch 2 only for the expansion/upgrade.
- Content: New story beats, remixed level routes, hidden paths, tougher enemy sets, and added Mouthful transforms.
- Performance: Reported 60fps with higher resolutions (up to 1440p docked) on Switch 2.

How to Access Star-Crossed World on Kirby
Step-by-step
- Buy/download the Nintendo Switch 2 Edition + Star-Crossed World or the Upgrade Pack from the eShop.
- Update your game and confirm the entitlement is active (Nintendo support has a checklist if the DLC isn’t showing).
- Play through Natural Plains in Story Mode—this triggers the Starry stages that open the expansion path on your map.
If Star-Crossed World doesn’t appear after updating, follow my Switch eShop install & DLC troubleshooting guide to fix entitlement issues fast.
Final Boss, Secret Boss, and How to Prepare
The Big Bad
The story climax features Genwel Meteonelfilis (Parastella Crystallis)—a crystalline, meteor-tied entity with multi-phase patterns. Expect projectile spreads, tracking beams, and arena shifts that reward short hops and i-frame dodges.
The Real Wall: Ultimate Cup Z EX
After credits, the Colosseum unlocks Ultimate Cup Z EX: an endurance run that layers enhanced boss movesets and a secret capstone encounter for the true 100-percenters. Think precise dodges, powered copy abilities, and Maxim Tomato rationing.
Loadout tips
- Prioritize evolved Sword or Ranger for safe damage and range.
- Save attack boosts for late phases; learn the boss’s “tell” before committing Waddle Dee Items.
- Perfect-dodge for slow-mo counters—Kirby’s combat looks simple, but the window is generous once you sync to it. (Move list depth and dodge timing are consistently highlighted in hands-on reviews.)
- Before the gauntlet, gear up with my best copy-ability evolutions and Colosseum builds for consistent clears and faster times.

How to Unlock The Ultimate Choice in Kirby Star Allies
- Unlock condition: Beat Story Mode once. The mode appears alongside Guest Star ???? Star Allies Go! and later connects to other post-game content.
- Higher difficulties: Clear runs to raise the heat, culminating in Soul Melter EX—the famous “don’t blink” tier. (Fandom wiki lists the cosmetic bonus for clearing it.)
How to Get 100% in Kirby Super Star (and Ultra)
For the SNES original and DS remake, 100% means clearing every sub-game and meeting each one’s specific completion requirements. A reliable checklist for Ultra includes:
- Spring Breeze (clear)
- Gourmet Race (win)
- Great Cave Offensive (60/60 treasures)
- Dyna Blade (activate both hidden switches)
- Milky Way Wishes (all 19 Copy Essences)
- Revenge of Meta Knight, The Arena, Revenge of the King, Meta Knightmare Ultra, Helper to Hero (every helper), and True Arena.
WiKirby’s 100% entry is a helpful cross-reference if you’re mixing versions or double-checking side tasks.
Walkthrough Pointers for Star-Crossed World
Exploration & Collectibles
- Follow environmental “sparkle” cues—reviewers note the expansion leans on visual breadcrumbs for hidden routes and Starries.
- Use new Mouthful forms to backtrack into previously unreachable geometry (elevators, rails, spring towers).
Combat Rhythm
- Evolve copy abilities early; the Switch 2 build’s smoother timing makes perfect-dodge → counter a core loop, especially in boss rush.

Conclusion
- Value add: Star-Crossed World makes a strong case for upgrading—fresh routes, sharper performance, and an endgame that hums.
- Plan of attack: Install the Switch 2 build, finish Natural Plains, sweep Starries, then test yourself in Ultimate Cup Z EX.
- Completionists: Use the 100% and Ultimate Choice checklists above to close the loop across Super Star, Ultra, and Star Allies.
