SPELLCASTERS CHRONICLES REABRE EL PORTAL A ASHKENON CON LA BETA CERRADA 2, YA DISPONIBLE EN STEAM
30 Ene, 2026
Esta Segunda Beta desbloquea nuevas posibilidades con nuevos hechizos e invocaciones, funcionalidades adicionales y otras mejoras. Además, incluye la primera nueva arena desde la presentación de Spellcasters Chronicles.
PARIS — 29 DE ENERO DE 2026 — Quantic Dream se enorgullece de anunciar que la segunda Beta Cerrada de Spellcasters Chronicles ya está disponible en PC a través de Steam. Los servidores abrieron hoy a las 16:00 CET y permanecerán accesibles hasta el 2 de febrero a las 10:00 CET. Esta nueva fase se fundamenta en las opiniones que los jugadores brindaron durante la primera Beta Cerrada, celebrada en diciembre de 2025, e introduce nuevos contenidos, funcionalidades que mejoran la experiencia de uso, así como mejoras técnicas en el camino hacia el lanzamiento del Early Access, programado para el 26 de febrero de 2026.
«La Beta Cerrada 2 marca un nuevo e importante capítulo para Spellcasters Chronicles», afirmó Gregorie Diaconu, Director de Juego en Quantic Dream. «Abrir el primer portal a Ashkenon nos enseñó mucho, no solo sobre nuestros sistemas, sino sobre cómo los jugadores se mueven, experimentan y se expresan dentro del juego. Esta segunda beta trata de interiorizar esas lecciones e integrarlas en la experiencia, reforzando el rendimiento, refinando la jugabilidad y expandiendo el caos mágico con nuevos hechizos, invocaciones y las Costas Nórdicas de Valm. Estamos entusiasmados de invitar de nuevo a los jugadores y de seguir dando forma a este viaje juntos a medida que nos acercamos al Early Access».
Visualiza el trailer de la Segunda Beta Cerrada de Spellcasters Chronicles aquí:
NUEVAS CARACTERÍSTICAS DE SPELLCASTERS CHORNICLES EN LA BETA CERRADA 2
La Beta Cerrada 2 incorpora una serie de nuevas características, entre las que se incluyen:
Introducción al juego y tutorial: una nueva experiencia de iniciación diseñada para ayudar a los nuevos jugadores a aprender los conceptos básicos.
Chat de texto de equipo dentro del juego: para que los jugadores se puedan comunicar entre sí durante las partidas.
Sistema de reporte de jugadores: para ayudar a abordar comportamientos tóxicos o inapropiados.
Personalización de Spellcasters y Lifestones: para que los jugadores prueben las funciones de personalización disponibles para los Spellcasters y las Lifestones.
Versión temprana del sistema de clasificación.
En esta segunda fase de pruebas también se expande el contenido jugable con:
La Costa nórdica de Valm: una nueva arena de 5 carriles que cuenta con líneas de visión abiertas, condiciones ambientales extremas un diseño distintivo.
Seis nuevos hechizos: los jugadores pueden incluir en sus mazos Lluvia de fuego (Fire Rain), Granada de veneno (Poison Grenade), Infusión de hielo (Ice Infusion), Infusión de fuego (Fire Infusion), Sacrificio (Sacrifice) y Resurrección ( Resurrection).
Cinco nuevas invocaciones: los jugadores pueden incluir en sus mazos a Stone Behemoth, Lich, Faery, Steam Tank y a Wolven Hunter.
Tres nuevos edificios: los jugadores pueden incluir en sus mazos el Nido de Arpías (Harpy’s Nest), el Baluarte (Rampart) y la Balista (Ballista).
Para obtener un desglose completo de los nuevos contenidos, los ajustes de equilibrio, las correcciones de errores, los problemas conocidos y las mejoras técnicas que llegan con la Beta Cerrada 2, los jugadores pueden consultar las notas del parche completas, disponibles junto con el lanzamiento de esta fase de pruebas.
Consulta las notas del parche de la Segunda Beta Cerrada aquí:
La Beta Cerrada 2 introduce la Costa nórdica de Valm, la segunda arena jugable desde la presentación de Spellcasters Chronicles. Ambientada en una costa escarpada marcada por un antiguo enfrentamiento entre las fuerzas de Valmide y criaturas de los reinos exteriores, la Costa nórdica se extiende sobre los restos de una guerra olvidada: desde barcos destrozados y armas colosales hasta los restos de bestias abisales esparcidos por los acantilados.
Construida en torno a un diseño único de cinco carriles, la arena favorece los enfrentamientos a ras de suelo, mientras que cuevas serpenteantes, senderos estrechos y rutas costeras ofrecen múltiples oportunidades para flanqueos, retiradas y emboscadas.
CONSTRUYENDO UN CAMPO DE BATALLA MÁS FLUIDO PARA EL SEGUNDO FIN DE SEMANA DE LA BETA CERRADA
