Partly, you can build a small battle royale first, but 100-player online matches take much more work.
You can build an original shooter with a small arena, computer opponents and a last-player-standing win condition. Real matches with 100 people need multiplayer hosting and many rounds of testing. Start with a playable solo version before adding online play.

The checker split your own version of Fortnite into its key parts and sorted each one.
Arena and shooting controls
Vibecode can build a simple 3D arena with movement, aiming and shooting.
Works out of the box
Computer opponents and survival
Start with simple computer opponents, health and a last-survivor win screen.
Works out of the box
Shrinking safe zone
Vibecode can add a visible safe zone that shrinks and damages players outside it.
Works out of the box
100-player online matches
An outside multiplayer service can run matches, but syncing movement and shots for 100 people needs extensive testing.
Takes more work
Match fairness and cheating
Online matches need a server to check player actions, plus repeated testing to catch cheating and lag problems.
Takes more work
A native Swift iPhone app is a good fit for a simple 3D game with touch controls.
Plan ahead: Treat 100-player matches as a later milestone, and test server load and fair hit detection before opening them to players.
Written by the checker for a first version. Paste it into Vibecode as is, or change it to make the app yours.
Build an iPhone app for people who want a quick, original battle royale shooter against computer opponents. Use a simple low-poly 3D style with green terrain, gray cover and clear orange danger zones. The main screen should show a small arena, the player's health and the number of opponents left. Add a left thumb control for movement and right-side controls for aiming and firing. Populate the arena with a small group of simple computer opponents and realistic sample match data. Add a safe zone that visibly shrinks and damages anyone outside it. When only one fighter remains, show a win or loss screen with a play-again button. Keep this first version local, without online multiplayer, and use original placeholder characters and scenery.

Vibecode builds a first version from one prompt, and the checker would start with these parts: a small 3D arena with touch movement and shooting; simple computer opponents with health and a last-survivor win screen; a shrinking safe zone. Plan on a few weeks for a working first version with its real features.
Vibecode's first build is free for new accounts that sign up with Google or Apple on the web or the iPhone app, as the account's first project: one build of about 10 minutes with up to 3 features, on sample data. After that you need credits, from a paid plan or auto-reload. For your own version of Fortnite, the checker lists these costs: Vibecode Plus ($20 a month); Apple Developer Program ($99 a year); API key for Photon (that service's pricing).
Fortnite gives players an established community to play with, licensed crossover characters, and an ongoing supply of content from Epic and creators. A version you build yourself won't have these: Fortnite's existing player community; licensed crossover characters and worlds; established creator community; Epic's live operations team.
