《R-Type Tactics I • II Cosmos》是結合橫向卷軸動作與回合制策略的創新遊戲合集，將經典的R-Type系列玩法與戰術策略完美融合，帶來全新的R-Type體驗。這個合集收錄原本分別在PSP推出的兩款作品——《R-Type Tactics》（西方稱為R-Type: Command）與《R-Type Tactics II: Operation Bitter Chocolate》，並進行現代化重製，不僅畫面煥然一新，還增加線上對戰、多重戰役、分支任務等內容，提供豐富且多樣化的遊戲體驗。

故事背景依舊延續R-Type宇宙觀：當Bydo勢力繼續向人類發動致命攻擊時，玩家將化身太空軍指揮官，運用智慧與策略擊退敵軍。然而，隨著戰局的推進，甚至可能需要與原本的敵人Bydo聯手作戰，故事情節充滿意想不到的反轉與緊張刺激的劇情。戰役設計分為多條路線，可操作不同陣營——無論是太空軍還是Bydo勢力——展開戰鬥，並透過選擇不同分支任務影響戰役結局，增加重玩價值。

操作方面，結合經典R-Type的橫向卷軸射擊元素，需控制各式戰艦，在動態戰場中靈活操控單位進行移動、攻擊及特殊技能使用。同時融入回合制策略玩法，每回合都需精心部署艦隊位置與技能施放，戰術思考占據核心地位。提供數百艘可操作戰艦，以及多樣化關卡挑戰，讓玩家可以自由組合戰術與隊伍編制，從而應對不同敵人與戰場環境。

於2026年3月12日在日本正式發售，登陸PlayStation 5、Switch 2及Switch平台，售價6380日元。Switch 2版本採用遊戲密匙卡形式發售。該合集亦宣布將登陸Xbox Series、PlayStation 4及PC（Steam、Epic Games Store）平台，其中《R-Type Tactics II》也是首次在西方地區亮相。

市場評價方面，由於結合射擊與策略兩種不同玩法，加上深度劇情和豐富的艦隊編制系統，受到玩家與評論界廣泛期待。玩家稱讚其策略深度高、操作手感流暢，同時對分支任務和線上對戰功能給予高度肯定。雖然開發過程歷經多次延遲，從最初2023年的預定發售推遲至2025年甚至2026年，但最終推出的作品因豐富內容與優化設計而獲得玩家普遍好評，被認為是R-Type系列在策略遊戲領域的一次成功嘗試，也為回合制策略愛好者提供兼具挑戰性與娛樂性的優質作品。

R-Type Tactics I • II Cosmos is an innovative game collection that combines side-scrolling action with turn-based tactical strategy, offering a unique fusion of classic R-Type gameplay and strategic depth. The collection includes remastered versions of two PSP titles—R-Type Tactics (known in the West as R-Type: Command) and R-Type Tactics II: Operation Bitter Chocolate—featuring modernized visuals, online multiplayer, multiple campaigns, and branching mission paths, providing a rich and varied gaming experience.

The story continues within the R-Type universe. As the Bydo forces relentlessly threaten humanity, players assume the role of a Space Corps commander, tasked with outsmarting and outmaneuvering the enemy. However, as the story unfolds, players may find themselves in situations where they must temporarily cooperate with the very Bydo forces they were fighting against. The campaigns feature multiple branching paths, allowing players to control different factions—either the Space Corps or the Bydo—and their choices directly influence mission outcomes, enhancing replayability.

Gameplay blends the classic R-Type horizontal shoot-'em-up mechanics with turn-based tactical strategy. Players must maneuver various ships across dynamic battlefields, carefully planning moves, attacks, and special abilities each turn. The game offers hundreds of ships and numerous levels, allowing players to experiment with different fleet compositions and tactical strategies to confront a wide variety of enemies and battlefield conditions.

R-Type Tactics I • II Cosmos was released in Japan on March 12, 2026, for PlayStation 5, Switch 2, and Switch, priced at 6,380 yen. The Switch 2 version is sold as a game key card. The collection is also announced for Xbox Series, PlayStation 4, and PC (Steam and Epic Games Store), with R-Type Tactics II making its Western debut for the first time.

Regarding reception, the game has been widely anticipated due to its combination of action and strategy, deep storylines, and extensive fleet management. Players and critics have praised its strategic depth, smooth controls, and engaging gameplay, while branching missions and online play have been highlighted as standout features. Despite multiple development delays—from an initial 2023 release pushed back to 2025 and finally 2026—the final product has been well-received. It is considered a successful evolution of the R-Type series into the tactical strategy genre, providing both challenge and entertainment for fans of turn-based strategy games.
