Sources & verification method

1. 1. Official Roblox APIs & pages — Identity, description, update notes, votes, badges, group facts. Highest trust — this is the developer's own surface. The description doubles as the news feed, so its rotation (AA2026 → 10KCCU) is tracked like patch notes.
2. 2. Official game art — Icon and thumbnails we inspected directly (not hot-linked), used for visual facts like the +67 per-shot gun example and the robot enemy designs. Dated to the inspection.
3. 3. Multi-source community trackers — Codes are listed as confirmed only when independent trackers agree — currently KodeGG/RoCodes.gg, urgametips, GameRant and Dexerto on the core working codes (10KCCU included since the 2026-10-13 check; re-read 2026-10-30), with Roblox Den read through KodeGG's cross-check after its direct fetch failed this run. Destructoid and Sportskeeda are read as additional opinions whose reward labels and code sets differ (both print 5KCCU at 100,000 Damage).
4. 4. Reported — Community-documented steps we did not run ourselves; always labeled “Reported”, like the in-game redeem flow.
5. 5. Unknown — Anything without a source stays labeled unknown with the check method named. We never estimate player-facing numbers.

Trackers of the same tier sometimes contradict each other. The site's rule is to show both entries with their dates instead of quietly choosing one. Two live examples from the 2026-10-30 check:

• BUDDY / RELEASE rewards: Roblox Den, urgametips, GameRant and Dexerto say “Sensei Buddy” and “1 Rebirth”; KodeGG's current list labels both “5k Dmg”, Destructoid's 2026-10-19 list “5k Damage” and Sportskeeda's 2026-10-08 list “5,000 Damage”. The codes page prints the four-source majority and keeps the outlier labels visible.
• 5KCCU: KodeGG/RoCodes.gg (checked 2026-10-30, the code Roblox Den saw 30 Oct), Destructoid (updated 2026-10-19) and Sportskeeda (2026-10-08) list it working with 100,000 Damage; GameRant (updated 2026-10-13) is the lone 10K-Damage dissent; urgametips's October 7 article and Dexerto (2026-10-12) omit it. The codes page prints the 100K majority with the 10K claim shown both ways.

The developer publishes update notes only in the Roblox description — no Discord, Trello or patch site is verified (see the status page). So the description is re-read at every site update and its changes are logged:

• 2026-09-16 (check): V1.2 notes: a Buddy that helps destroy enemies, and "Stages BOSS". The buddy callout and the boss system both debut here.
• 2026-09-24 (check): V1.3 notes: "Added More Buddies and improved system / Fixes a few bugs." New code callout: "use code AA2026 for 1 Random Buddy!"
• 2026-10-05 (check): Title carries the [W2] tag; the description's code callout has rotated to "use code \"10KCCU\" for some GIFT!". The AA2026 callout is gone from the description — the callout slot advertises one code at a time.
• 2026-10-13 (check): The game's API update timestamp moved to 2026-10-10, but the description text is unchanged and still advertises 10KCCU. No new version notes and no new code callout since the 2026-10-05 check; the trackers have since confirmed 10KCCU with a rebirth reward.
• 2026-10-20 (check): The game's API update timestamp moved to 2026-10-16, but the description text is unchanged and still advertises 10KCCU — no new version notes, no new code callout. The 2026-10-20 tracker sweep (Roblox Den, urgametips, KodeGG, GameRant 10-13, Dexerto 10-12 and Destructoid re-read directly) found no new code and no expiry; the 5KCCU reward dispute widened (10K vs 100K damage claims), and the neighbor game's title tag rotated to a [Halloween] stamp.
• 2026-10-30 (check): The game shipped its [W3] update: the title rotated to "[W3 UPDATE!] +1 DMG FPS" and the API update timestamp moved to 2026-10-29T01:56Z, but the description text is unchanged and still advertises 10KCCU — no new version notes, no new callout. The official Events panel shows "World 3 + Admin Abuse — World 3 is here!" live and lists an upcoming "NEW WORLDS!!" update event (Sun, Nov 1, 6:00 AM). The 2026-10-30 tracker sweep (KodeGG/RoCodes.gg live, Destructoid 10-19, Sportskeeda 10-08, GameRant 10-13, Dexerto 10-12, urgametips 10-07; Roblox Den via KodeGG's cross-check after its direct read failed) re-listed 5KCCU as active with a 100,000-Damage claim, and the neighbor game's title rotated again at its 2026-10-30 update.

• 2026-10-30 —
• 2026-10-20 — Re-check after the game's 2026-10-16 API update: description unchanged, still advertising 10KCCU — no new code callout, no new version notes. Snapshot 751 playing / 13,056,808 visits / 507,118 favorites / 117,142 up-votes (96.2%); group at 2,584,643 members; badge past 5,736,698 awards. Tracker sweep re-read directly: Roblox Den (6 active / 0 expired), urgametips, KodeGG, GameRant (updated 2026-10-13), Dexerto (updated 2026-10-12, added to the register) and Destructoid (October 2026 article, added to the register — lists 5KCCU 100k Damage and omits 10KCCU/AA2026). 5KCCU dispute widened to a reward-amount conflict (10K vs 100K). Neighbor game title tag rotated to a [Halloween] stamp at its 2026-10-19 update.
• 2026-10-13 — Re-check after the game's 2026-10-10 API update: description unchanged, still advertising 10KCCU. Snapshot 1,646 playing / 12,187,409 visits / 482,502 favorites / 110,942 up-votes (96.2%); group at 2,438,416 members. Tracker sweep: Roblox Den (re-read, 6 active / 0 expired, 10KCCU credits a Rebirth), urgametips (updated 2026-10-11, 10KCCU added to the working list on 2026-10-07 as a Rebirth), KodeGG (read 2026-10-13, 6 verified) and GameRant (2026-10-01, 5KCCU claim unchanged). Neighbor game moved to [Upd13].
• 2026-10-05 — Full API sweep: title now reads “[W2] +1 DMG FPS”; description's code callout rotated to 10KCCU; snapshot 2,575 playing / 9,299,718 visits / 88,908 up-votes (96.2%); group at 1,820,526 members (tier 3); Defender of Earth badge past 4,070,000 awards. Roblox Den (stamp 2026-10-03), GameRant (2026-10-01), urgametips (2026-09-25) and KodeGG re-read for the codes tables.
• 2026-09-27 — Codes re-verified: Roblox Den (stamp 2026-09-26) and KodeGG agreed with the official description's AA2026 callout on all five codes and rewards. Group shout checked (empty).
• 2026-09-24 — V1.3 update captured from the description: “Added More Buddies and improved system / Fixes a few bugs.” plus the AA2026 announcement. GameRant's 5KCCU claim logged as single-source.
• 2026-09-16 — Launch-day baseline: V1.2 notes (Buddy + “Stages BOSS”), official art inspection (+1 starter vs +67 crystal rifle), neighbor-game identity check, badges API (Defender of Earth).

The homepage status numbers come from the official Roblox API. At each site build we refresh the snapshot and stamp the exact check time; between builds the page shows the last snapshot with its date, never a made-up “live” number.

• We have not personally playtested every redeem step — those are labeled Reported.
• Rebirth/medal/gun-list numbers are absent from every source we check; they stay as named unknowns on the guide.
• No official social channels are verified (see the status page) — none are invented here.
• Creator videos are cited for coverage context with their titles; their in-game claims are only repeated where a tracker or official source corroborates them.

+1 DMG FPS's developer publishes everything through the Roblox game page: the description doubles as the news feed, and there is no official stat table, Discord or patch-note site. This site therefore treats the official APIs and the description as the top source, lists community code claims only when trackers corroborate them, attaches a checked date to every table, and prints conflicting tracker claims both ways (as with the 5KCCU dispute) instead of quietly picking a winner. Anything the game itself does not reveal — rebirth formulas, medal rates, the full gun list — stays labeled unknown rather than filled with guesses.
