《微小世界生存戰2》（英文名稱：Grounded 2，中國大陸譯作「禁閉求生2」）是由Obsidian Entertainment聯手Eidos‑Montréal所打造的續作，於 2025年7月29 日於Steam搶先體驗平台與Xbox Game Preview上推出，並同步登上Xbox Game Pass。遊戲延續前作的迷你視角與開放世界合作生存玩法，但在劇情、玩法與系統面上都進行了大幅升級。

背景設定仍是1990年代的美國郊區，不過這次舞台從後院延伸到名為「Brookhollow公園」的廣闊自然區域。玩家再度扮演一群被縮小到蚂蚁大小的青少年，這場奇幻冒險不再只是求生，更揭露了前作未解的秘密。這片看似寧靜的公園其實暗藏危機，許多新出現的變異生物、超自然現象與科學陰謀，將挑戰玩家對世界的理解。

操作方面，依舊提供第一與第三人稱視角自由切換，支援單人與最多四人合作模式。遊戲核心圍繞資源採集、基地建設與裝備製作，但這次更強化探索與角色成長的要素。可解鎖各種技能與屬性調整，提升在環境中生存的能力。最大的亮點之一是「馴服與騎乘系統」，可與特定昆蟲建立聯繫，將牠們作為坐騎使用，如火蟻、跳蛛等，不僅提升移動效率，也改變戰鬥策略。

戰鬥部分也有所進化，加入更加細緻的閃避、格擋與技能組合設計，配合多種武器與工具。例如主角的「多功能工具」（Omni‑Tool），集結鏟子、斧頭與錘子的用途，讓玩家能一邊戰鬥一邊解謎，或在探索中發現隱藏路徑。

在畫面表現方面，因使用Unreal Engine 5引擎，整體畫質明顯提升。不僅細節豐富，光影與環境互動也更加逼真。製作團隊也貼心設計「蜘蛛安心模式」，可將遊戲內的蜘蛛模型轉化為可愛風格，照顧對蜘蛛恐懼症的玩家。

從媒體預覽與玩家試玩回饋來看，目前獲得多數正面評價。像是CGMagazine形容遊戲世界如同一場「玩家夢境般的冒險」，GamesRadar 則稱讚本作騎乘系統與使用者介面比前作成熟許多。Reddit社群亦有不少玩家認為，比起Obsidian近年推出的RPG更令人期待。不過也有評論如PC Gamer指出部分近戰武器手感仍稍嫌粗糙，戰鬥節奏尚可優化。

整體而言，《微小世界生存戰2》不僅擴大世界規模與玩法深度，更深化故事敘事與玩家角色的成長系統。無論是老玩家還是初次接觸本系列的新手，都能在這個充滿冒險與細節的微觀世界中找到屬於自己的生存樂趣。這是融合生存、合作、探險與創意建造的遊戲佳作，有望成為2025年度最亮眼的合作生存遊戲之一。

Grounded 2 (Chinese title:《微小世界生存戰2》, known in mainland China as 「禁闭求生2」) is the sequel collaboratively developed by Obsidian Entertainment and Eidos Montréal. The game launches on July 29, 2025, via Steam Early Access and Xbox Game Preview, and is also available on Xbox Game Pass at launch. Like its predecessor, it features a miniaturized perspective and open-world cooperative survival gameplay, but this time with major upgrades in story, mechanics, and systems.

The setting remains in suburban America during the 1990s, but the playable area now expands from the familiar backyard into a much larger natural zone called Brookhollow Park. Players once again take on the roles of teenagers shrunk to the size of ants. This fantastical adventure is no longer just about surviving the backyard—it now unravels the mysteries left behind by the first game. Beneath the surface of the tranquil park lie dangerous secrets, including new mutated creatures, supernatural phenomena, and scientific conspiracies that challenge players’ understanding of their miniature world.

In terms of gameplay, the title retains its flexible first-person and third-person perspectives and supports both solo play and four-player co-op. The core loop still revolves around resource gathering, base building, and gear crafting, but this time there's a much greater emphasis on exploration and character progression. Players can unlock new skills and attribute modifiers to improve survival capabilities. One of the game's most exciting new features is the taming and riding system, which allows players to bond with specific insects—such as fire ants and jumping spiders—and use them as mounts. These companions not only enhance traversal but also offer new tactical options in combat.

Combat mechanics have also been enhanced, now including refined dodging, blocking, and skill combos, as well as a wider array of weapons and tools. The protagonist’s new Omni Tool is particularly notable—this multi-functional device combines the abilities of a shovel, axe, and hammer, enabling players to battle enemies, solve puzzles, and uncover hidden paths during exploration.

Visually, Grounded 2 benefits from the power of the Unreal Engine 5, leading to a significant leap in overall graphical fidelity. The game features rich environmental details, more realistic lighting, and dynamic interactions with the surroundings. The developers have also included an “Arachnophobia Mode”, which transforms in-game spider models into cute, cartoonish alternatives, making the game more accessible to players with spider phobias.

Initial impressions from media previews and player demos have been largely positive. CGMagazine described the world as “a dreamlike adventure for players,” while GamesRadar praised the improved mount system and much more refined user interface compared to the original. Many users on Reddit have expressed that Grounded 2 is even more exciting than some of Obsidian’s recent RPG releases. However, some critics, such as PC Gamer, noted that certain melee weapons still feel a bit unpolished and that the combat rhythm could benefit from further tuning.

In summary, Grounded 2 not only expands the scale and depth of its world and gameplay but also deepens its storytelling and player progression systems. Whether you're a returning fan or new to the series, this intricate micro-world offers a unique survival experience filled with adventure and creativity. As a blend of survival, co-op, exploration, and imaginative construction, Grounded 2 is poised to become one of the standout cooperative survival games of 2025.
