《紅色的鍊金術士和白色的守護者 ～蕾斯萊莉婭娜的鍊金工房～》是由Koei Tecmo Games開發與發行的角色扮演遊戲，於2025年9月26日推出。屬於長壽系列鍊金工房系列的一部分，在延續系列核心「鍊金術×冒險×角色劇情」的基礎上，加入更多經營與隨機探索要素，試圖在傳統框架中帶來更完整的系統整合。

故事背景設定在曾經因礦業與貿易繁榮的邊境城鎮「哈爾費恩」。這座城市過去因突如其來的神秘災害，導致大部分居民一夜之間消失，整座城鎮因此被列為禁地並長期封鎖。隨著時間推移，禁令解除，城鎮重新被納入復興計畫，塵封的過去也再度被揭開。

在這樣的背景下，兩位主角各自回到故鄉。少女為了奪回已故祖父留下的店鋪，少年則為了追查父親遺留下來的線索。他們在相同的時間點回到這座殘破卻逐漸復甦的城鎮，並因共同目標而相遇，開始一同追查當年居民集體消失的真相。然而，隨著調查深入，他們逐漸接觸到遠超預期的秘密與命運交錯的真相，也讓整個故事逐步轉向更為沉重的方向。

遊戲系統方面，延續系列一貫的鍊金玩法，但在設計上更強調策略性與流程整合。戰鬥採用「時間軸指令制戰鬥系統」，隊伍分為前衛與後衛兩個區域，最多可容納六名角色同時參與戰鬥。玩家需要透過行動時機的安排、技能連鎖以及道具組合來掌握戰局，使戰鬥不僅依賴數值，更重視策略節奏。

探索部分則導入更動態的環境系統，包含晝夜變化與天氣變化，這些因素會影響採集素材與戰鬥條件。此外，玩家可以隨時切換兩位主角，各自擁有不同的地圖行動能力，使探索路線與互動方式更加多樣化。

亦加入名為「亞空之道」的隨機地下城系統，每次進入時地圖結構與敵人配置都會變化，屬於典型的roguelike式設計。隨著難度提升，玩家可以取得更稀有的素材與裝備，其中包含被稱為「星珠」的特殊道具，成為強化角色與裝備的重要來源。

鍊金系統則以「禮物色彩調合」為核心，透過素材顏色的連結來繼承特性，使製作過程既直覺又保留深度。同時，加入額外素材槽位機制，讓玩家能進一步強化完成品性能，並透過特定組合解鎖新配方，使鍊金不再只是單純合成，而是策略與資源規劃的一環。

除了戰鬥與鍊金，也強化城鎮經營要素。將製作出的道具在自己的商店中販售，藉此賺取資金並投入城鎮復興。隨著經濟與建設逐步發展，不僅會解鎖新的鍊金配方，也會推進主線劇情，使經營系統與敘事進度緊密連動。

角色方面，除了兩位原創主角之外，亦收錄多名系列歷代角色作為可操作角色登場，包括羅潔魯克斯·邁森、托托莉亞·赫爾莫爾特、威爾貝兒·佛爾＝艾爾斯莉特以及蘇菲·諾伊恩繆拉等，進一步強化系列世界觀的連結性。

整體市場評價方面，被視為《鍊金工房》系列在系統層面的一次擴展與整合嘗試。透過結合戰鬥策略化、隨機探索與城鎮經營，使遊戲循環更加完整，也讓玩家在鍊金之外擁有更多長期目標。市場普遍認為，本作屬於穩定型JRPG作品，並不以爆發性銷量為目標，而是延續系列一貫的中高評價與穩定粉絲基礎，維持長線經營型作品的定位。

Atelier Resleriana: The Red Alchemist & the White Guardian is a role-playing game developed and published by Koei Tecmo Games, scheduled for release on September 26, 2025. It is part of the long-running Atelier series, which is known for combining alchemy-based crafting systems with character-driven storytelling and light fantasy adventure elements. This entry expands the traditional formula by integrating more simulation and exploration systems while maintaining the series’ core identity.

The story is set in the town of Halphen, a former mining and trade hub located at the crossroads of three regions. The town once prospered but suffered a mysterious disaster in which most of its population suddenly disappeared. As a result, it was sealed off as a restricted zone for years. Eventually, the ban is lifted and a reconstruction plan is launched, allowing the town to slowly begin recovery while the truth of the past remains buried.

Against this backdrop, two protagonists return to their homeland for different reasons. A young woman comes back to reclaim her grandfather’s abandoned shop, while a young man seeks clues left behind by his father. Their shared goal of uncovering the truth behind the mass disappearance brings them together, and they begin investigating the hidden secrets of their hometown. As their journey progresses, they encounter unexpected truths that go far beyond what they initially imagined, gradually revealing a deeper and more complex fate tied to the town itself.

In terms of gameplay, the title retains the traditional Atelier alchemy system but enhances its strategic depth. Combat uses a timeline-based command battle system, where characters are divided into front and back lines, supporting coordinated actions, skill chains, and item combinations. This creates a system where timing and tactical decisions are just as important as character strength.

Exploration takes place in dynamic environments featuring day-night cycles and changing weather conditions, both of which influence gathering and combat behavior. Players can freely switch between the two main characters, each offering unique field abilities that affect how areas are explored and interacted with.

A major feature of the game is the “Abyssal Corridor,” a procedurally generated dungeon system where layouts and enemy placements change with every run. As difficulty increases, players can obtain rarer materials and powerful equipment, including special items known as “Star Orbs,” which play an important role in character and gear development.

The alchemy system is built around “Gift Color Synthesis,” where materials are combined based on color attributes to transfer traits into crafted items. Additional ingredient slots allow further enhancement of item performance, and certain combinations unlock new recipes, making synthesis a strategic system rather than a simple crafting mechanic.

Beyond combat and alchemy, the game also features town development and shop management systems. Items created through synthesis can be sold in the player’s shop, generating income that is reinvested into rebuilding the town. As development progresses, new recipes and story events are unlocked, tightly linking economic growth with narrative progression.

The game also includes returning characters from previous Atelier titles as playable allies, including Roselux Maizen, Totori Helmold, Wilbell Voll-Ersleid, and Sophie Neuenmuller, further connecting the game to the broader franchise continuity.

Overall, the game is positioned as a systems-expansion entry in the Atelier series, combining traditional alchemy mechanics with deeper combat strategy, procedural dungeon exploration, and town management. Rather than focusing on explosive mainstream sales, it is expected to perform as a stable, long-running JRPG title, supported by a dedicated fanbase and the enduring popularity of the franchise.
