Riftline

Riftline is a first-person hero shooter that runs straight in the browser. You play Vesper, a 150 HP skirmisher with twin pistols, a short teleport, a rewind that undoes the last three seconds, and a sticky charge as an ultimate. The map is Solace Harbor.

Two ways to play

• Practice: 1 to 3 bots on Easy, Normal or Hard. The first to 10 eliminations wins. Set the bots to None for free roam, where the ultimate charges every 15 seconds so you can practise it.
• Online duel: one player hosts a room and sends the link or the five-letter code, and the other joins. Play is peer to peer over WebRTC: a free PeerJS broker only introduces the two browsers, then game traffic goes directly between the players. Some strict corporate or university networks block peer-to-peer connections.

How it's built

No build step and no server: plain ES modules, three.js r160 and PeerJS, served from GitHub Pages. Models, materials, textures and sound are all generated in code. Online, each client simulates its own hero and sends 20 snapshots a second, and remote players are drawn 100 ms in the past and interpolated. Hits are checked by the shooter and applied by the victim, so a rewind in progress still saves you. It's a casual model with no cheat protection.

How it was made

The repository is described as "testing Claude Fable 5.2 for game dev." Its commit history credits Claude Opus 5.5 with the current version 2 (readable source, the original blink hero, the twin-pistol view and online play) and Claude Fable 5.2 with the free-roam mode and the online fixes after it. The original single-file version 1 is kept in the repo's legacy/ folder.

Vesper's kit

Key	Ability	Details
Left mouse	Twin Pistols	40 rounds, very fast fire. Damage falls off from 11 m to 30 m. Headshots deal double damage.
Shift / right mouse	Skip	Teleport 7.5 m in the direction you're moving. 3 charges, each recharging in 3 s.
E	Rewind	Travel back along your path to where you were 3 s ago, untouchable on the way, and arrive with that health and full ammo. 12 s cooldown.
Q	Tick Charge (ultimate)	A sticky charge that detonates 1 s after it lands, for 350 damage at the centre. Charges by dealing damage.

Tips

• Fight inside 11 metres. Pistol damage falls off beyond that, and aim for the head for double damage.
• Skip toward cover or behind your target, not just away. With three charges you can go in and come back out.
• Rewind is a heal and a reload. Use it after taking damage, ideally when you're also out of ammo, since you return with your earlier health and a full magazine.
• Online, Rewind still saves you from a shot already on its way, because the victim's client applies the damage.
• Stick the Tick Charge to a target or a doorway; at 350 damage at the centre, it ends most fights.
• In free roam the ultimate recharges every 15 seconds, which makes it a good place to learn its timing.
