Features

Automation Engine

Lambda can autonomously build structures. We use Litematica as an interface, while our building engine handles the complex orchestration, block states, and rotations.

Unmatched Performance

Optimized rendering pipelines using batched rendering for superfast ESP. Modern frameworks ensure speed and responsiveness.

Sophisticated UX

Fine-tune over 1000+ settings with the clean Dear ImGui interface. Use Automation Profiles to switch complex configs instantly.

Safety & Tools

Built with Grim Anticheat compatibility in mind. Includes the new HighwayTools, rewritten to use the powerful build engine for efficient maintenance.
