Steel Fighters received an Index in Update 1. The official event confirms the feature, while the official experience description establishes a collection based on parts from more than 100 robots. Public official pages do not expose the complete roster, every part, tier requirement, or reward, so this page is a method and a known-record format rather than a fabricated “all robots” table.
Open the current Index in the game and treat it as the authority. A visible silhouette can prove that an entry exists; it cannot prove the English name, stats, rarity, acquisition odds, or best build until those fields appear elsewhere in the interface.
Index record fields
Start with the live Index
Open the Index and scan each visible tier before spending. Record how the interface defines completion: discovered robots, obtained parts, completed sets, built robots, or another condition. Similar collection games use different rules, so the presence of a percentage bar does not reveal its denominator.
For each visible named robot, capture the detail view and part requirements. If the game shows only a silhouette, label it Unknown Index entry with its position and tier rather than assigning a name from a video thumbnail. When the entry is later revealed, update the record at the same canonical route instead of creating a duplicate.
Plan collection around missing pieces
Sort missing entries by action, not only by rarity. A missing piece may come from the lever, a social reward, a mode, an event surface, a boss, the Spin Wheel, Fusion, or another source visible in the current UI. Grouping by source lets you complete several rows during one session.
Set a budget before random pulls. Stop when you reach the target, hit the budget, or discover that the source does not show the expected pool. Luck Titles may affect a roll that explicitly uses Luck, but the official sources do not publish exact odds. Do not turn a percentage benefit into a claimed part probability.
Keep untested parts until you know whether the Index requires ownership, discovery, a complete set, or a built robot. Consuming or fusing the only copy can block a tier if the system checks current inventory rather than historical discovery.
Claim and verify a tier reward
Before claiming, record the tier requirement and your current Cash, Scrap, robots, permanent boosts, and other relevant counters. Claim once and capture the result message. Reopen the Index or rejoin if the UI does not visibly update.
Current third-party guides report tier rewards and permanent boosts, but exact tiers and effects need the live client. Verify permanence by checking after a rejoin and, when safe, after a Rebirth. Verify a boost by repeating the same controlled reward or Arena test. Do not claim that all Index rewards survive every reset from one example.
A useful known-robot Dex
The full public roster is not available from official sources, so the responsible Dex begins with verified fields rather than guessed names. Add an entry only when the current Index or another in-game screen shows its identity. Include:
- exact robot name;
- every displayed part slot;
- collection state and tier;
- acquisition source for each known piece;
- visible effect or build contribution;
- whether a complete matching set was tested;
- source, evidence status, and check date;
- a detail route only when there is enough unique material for one full page.
That structure remains searchable without pretending the collection is complete. It also lets Robot Parts and Robot Builds link to one record rather than copying stats into several pages.
Avoid Index mistakes
Do not count a promotional “100+ robots” statement as a verified current roster table. Do not name a silhouette from its outline. Do not assign a rarity from border color without a visible label. Do not publish a tier reward from a preview unless it was claimed or the current panel clearly states it.
Do not delete a part after it appears in the Index until you understand whether completion is historical or inventory-based. Do not use a target-locale or old-version screenshot as proof of current English terminology unless the item identity is independently linked.
What to do after completing a row
Compare the newly completed set with your current mixed build using the same robot level, upgrades, Title, and Arena floor. If the current UI shows a matching-set or Perfect benefit, capture it in the complete build summary. Keep the result attached to the test conditions.
If the Index reward changes progression, continue to Upgrades to classify it separately from ordinary robot spending. If a missing part comes from a mode, use Modes to verify its current entry and reward rules.
