Aegis Nexus

A cinematic 3D tower-defense strategy game built with Babylon.js 9 and Webpack. Place defenses anywhere valid, bend live A* routes around natural obstacles, and hold a procedurally varied battlefield through twelve escalating waves.

Play Aegis Nexus

Built in under 24 hours: Aegis Nexus was created in less than 24 hours of real time using ChatGPT 5.6 Sol Max.

Highlights

• Live A* navigation recalculates around natural obstacles and every placed tower; route-sealing placements are rejected.
• Two procedural portals can spawn along the rear or the ingress half of either side edge, then converge into a shared central route.
• Placement mode previews the exact changed route with a dashed line and shows firing coverage as subtle green/red ground tint.
• Four color-coded defense classes have class-specific traverse speed, muzzle fire, upgrades, and three distinct visual tiers.
• Nova artillery ignores direct line-of-sight blockers but has a visible red minimum-range dead zone.
• Six color-coded hostile chassis include articulated movement, shields, armor, support behavior, and pooled destruction fragments.
• Twelve tuned waves, early-launch bonuses, 1×/3× simulation, pause/restart flow, synthesized audio, and strategy controls.
• PBR materials, filtered shadows, bloom, pooled particle effects, adaptive resolution, and an internal deterministic JPEG visual harness.

Controls

Input	Action
W / S	Pan up / down
A / D	Pan left / right
Arrow keys	Pan in conventional screen directions
Left-, middle-, or Alt + left-drag	Grab-pan the battlefield
Right-drag	Orbit camera
Right-click	Cancel tower placement
Mouse wheel	Zoom
1–4	Select a defense platform
U	Upgrade selected platform
F	Launch the next wave early
Space	Pause
Esc	Cancel, close selection, or open the pause menu

The simulation-rate control toggles directly between 1× and 3×.

Local development

Requirements: Node.js 22.13 or newer, npm, and a WebGL 2-capable browser.

npm install
npm run dev

Open http://127.0.0.1:8080/.

Verification and visual tools

npm test
npm run build
npm run check:pages

Additional tools:

• npm run audit:game renders deterministic loading, menu, tower-tray, standby, first-tower, and Nova-coverage JPEGs in headless Edge. It also verifies loading typography and settled multi-angle frame stability.
• npm run audit:models renders four-direction JPEG contact sheets for every tower tier, enemy, wreck set, and environment prop.
• npm run audit:coverage renders the obstacle-blocked firing-sector audit.
• npm run audit:routes renders the converging-route audit.
• Run npm run dev and open http://127.0.0.1:8080/foundry.html for the interactive model foundry.

See the game audit, model audit, coverage audit, and route audit.
