The branching missions in R-Type Tactics are dictated by specific, often hidden, in-mission objectives, not by simple dialogue choices. For your first playthrough of the Human campaign in R-Type Tactics I, your path is locked in by critical actions taken in Stage 06 and, most pivotally, Stage 21. These choices determine which set of levels you'll face, what units you can develop, and ultimately, whether you'll unlock the game's second full campaign.
Unlike many strategy RPGs where paths diverge at a menu screen, R-Type Tactics embeds its most significant branches directly into the gameplay. Succeeding or failing at certain objectives, or even performing a counter-intuitive action, can send your fleet down a completely different strategic rabbit hole. This guide breaks down every major branching point across R-Type Tactics I • II Cosmos so you can navigate the war against the Bydo on your own terms.
How Mission Branching Actually Works
At its core, the branching system in R-Type Tactics I is a story and content gatekeeper. The main campaign, following the Earth Space Corps, has two primary junctures that split the narrative and the available missions into distinct 'A' and 'B' routes. The 'A' route is typically the more straightforward path, achieved by completing the mission's explicit primary objective. The 'B' route, however, often requires you to think outside the box, sometimes by failing an objective on purpose or achieving a more difficult secondary goal.
The choice you make at these junctures is permanent for that playthrough. You cannot go back and play the other branch until you have cleared the game, at which point you can revisit individual stages. The most significant outcome of this system is the method for unlocking the Bydo campaign, which requires a specific, seemingly disastrous outcome in the final human mission.
The Human Campaign's Critical Junctures
The Human campaign in the first game contains 30 missions, but you will only play through a fraction of the total possible stages in a single run due to branching. The two points where your path is irrevocably altered are:
- Stage 06, "Solar Furnace": This early-game choice determines the entire middle act of your campaign. The decision here splits the mission list from Stage 07 through Stage 14 into either the 'A' or 'B' track.
- Stage 21, "Bydo Seed": This is the big one. Your actions in this mission determine the ending of the Human campaign and whether you fulfill the condition to unlock the playable Bydo campaign for your next game.
The Bydo Campaign Path
The Bydo campaign is a full-fledged, 27-mission storyline played from the perspective of the Bydo Empire. It is not accessible from the start. To unlock it, you must first complete the Human campaign by achieving the specific "bad" ending in Stage 21. Once unlocked, you can select it from the main menu on a new save file. The Bydo campaign itself is more linear than the human one, but it provides crucial story context and a formidable roster of biomechanical units to command.
The First Major Choice: Stage 06 (Human Campaign)
Mission 06, "Solar Furnace," presents you with a massive solar energy weapon that the Bydo are attempting to control. Your official objective is to destroy the furnace's core before it can fire. However, a large Bydo fleet is also present. This is where the path splits.

Path 6A: Destroy the Core (Standard Route)
This is the most direct path. To proceed down Route A, you must focus your firepower on the Solar Furnace Core and destroy it within the mission's time limit. This is what the game explicitly tells you to do.
- Objective: Destroy the enemy flagship (the Solar Furnace Core).
- Outcome: You prevent the superweapon from firing, earning a decisive but conventional victory. You will proceed to Stage 07A, "Space Cemetery," and continue on the 'A' set of missions.
- Rewards: This path offers a standard progression of R-series fighters and capital ships. It's considered the slightly easier of the two routes.
Path 6B: Defeat All Forces (Alternate Route)
To unlock the more challenging and rewarding 'B' path, you must ignore the primary objective. Instead of attacking the furnace core, you must systematically destroy every single enemy Bydo unit on the map.
- Objective: Destroy all enemy units except for the Solar Furnace Core.
- Outcome: By letting the timer run out while methodically eliminating the Bydo fleet, you fail the primary objective but achieve a more thorough tactical victory. This unlocks Stage 07B, "Bewilderment," and the subsequent 'B' missions.
- Rewards: Route B is tougher, featuring more complex maps and stronger enemy compositions. However, it provides access to unique and powerful unit blueprints, such as advanced Force devices and experimental R-craft, that are unobtainable on Route A.
| Path | How to Unlock | Subsequent Missions | Key Unlocks & Difficulty |
|---|---|---|---|
| Route 6A | Destroy the Solar Furnace Core within the time limit. | Stages 7A, 8A, 9A, etc. | Standard unit progression. Considered the easier path. |
| Route 6B | Destroy all Bydo units, letting the timer expire. | Stages 7B, 8B, 9B, etc. | Access to exclusive, powerful unit blueprints. Higher difficulty. |
Unlocking the Bydo Campaign: Stage 21
Late in the Human campaign, you'll reach Stage 21, "Bydo Seed." This mission takes you to the heart of a Bydo infestation to destroy its core. The fate of your commander and the key to unlocking the game's second half hinges on your actions here.
Path to the Standard Ending
Your stated goal is to destroy the large, organic Bydo Seed at the center of the map. If you assault it with your fleet and reduce its health to zero, you will complete the mission normally.
- Objective: Destroy the Bydo Seed.
- Outcome: You achieve a heroic victory, destroying the Bydo core and seemingly ending the threat. The game concludes with the "good" ending for the human forces. However, this will not unlock the Bydo campaign.

Path to the True Ending and Bydo Campaign
To see the canonical conclusion of the human story and unlock the Bydo campaign, you must make a sacrifice. Instead of destroying the Bydo Seed, you must move your flagship—the Izanami—into the hexes immediately adjacent to the Bydo Seed. The Seed has a capture or absorption attack.
- Objective: Move your flagship next to the Bydo Seed and allow it to be captured.
- Outcome: Your flagship is absorbed by the Bydo, and your commander is presumed Missing in Action. This triggers the "bad" ending for the Human campaign, where your fleet is assimilated. After the credits roll, the game will notify you that the Bydo campaign is now available to play from the main menu.
This act is the canonical event that leads into the Bydo campaign, where you awaken as a commander within the Bydo hive mind, tasked with fighting back against your former comrades.
What About R-Type Tactics II?
The sequel, R-Type Tactics II: Operation Bitter Chocolate, also features branching missions, but the system is more nuanced and integrated into the story. Rather than one or two massive splits, Tactics II presents choices through journal entries and diverging paths based on which human faction you side with at the start: the Earth Allied Armed Forces (EAAF) or the Granzella Revolutionary Army (GZRA).
Key Divergence Points in Tactics II
The campaign structure is different, split into chapters. The first chapter has distinct mission lists depending on whether you play as the EAAF or GZRA. While many maps are shared, the story context, enemy placements, and available units differ.
- Faction Choice: Your initial choice between the EAAF and GZRA sets you on a unique path for the first part of the game.
- Mid-Campaign Splits: The story diverges again later on, around missions 18 and 19, leading to different final encounters for the game's first major act.
- Objective-Based Unlocks: Many missions contain optional objectives or hidden conditions that don't split the entire campaign, but instead unlock secret side missions or valuable unit blueprints. For example, protecting an allied transport on one map might unlock a bonus mission, while capturing a specific enemy structure might grant access to a new branch of the technology tree.
The branching in Tactics II is less about choosing between "Path A" and "Path B" and more about shaping your specific journey through the war, with your performance and choices yielding different rewards and narrative flavor along the way.

Frequently Asked Questions (FAQ)
Can I go back and play the other branch? Yes, but only after you have completed the campaign. Once you finish a playthrough, you gain access to a mission select screen where you can replay any stage, including those on the path you didn't take. This is essential for unlocking all units and seeing all the content.
Do I have to beat the game to unlock the Bydo campaign? Yes. You must complete the entire Human campaign in R-Type Tactics I by getting your flagship captured in Stage 21. After viewing the ending and saving your clear data, you can start a new game and select the Bydo campaign.
What's the "best" path to take in the Human campaign? For a first playthrough, either path is valid. Route 6A is more straightforward. However, Route 6B is generally considered more rewarding due to the exclusive, high-performance units you can develop. If you're looking for a challenge and the best possible fleet, aim for Route 6B.
Does my path choice affect what units I can develop? Absolutely. This is one of the most important consequences of branching. Route 6B in Tactics I grants access to several R-craft and Force blueprints that are completely unavailable on Route 6A. To complete your unit development tree and acquire 100% of the ships, you will need to play through both branches via mission select.
Final Thoughts
The branching mission system in R-Type Tactics is one of its most compelling features, transforming a linear strategy game into a puzzle of discovery and replayability. It rewards players who experiment and think beyond the most obvious objective, hiding entire campaigns and powerful arsenals behind clever, counter-intuitive gameplay choices. Unlocking the Bydo campaign by sacrificing your commander remains one of the most memorable moments in the series, perfectly capturing the grim, high-stakes tone of the war against an all-consuming foe.
