Submariner

A Twitch Chat Survival Voyage — AI Kills Band
Based on an idea/concept by Children of the Aftermath
Voyages currently depart weekly via twitch.tv/ai_kills
Submariner is a chat-integrated survival game — you and everyone else watching pilot a biological submarine together, live during AI Kills Band Twitch streams. Every stream is one voyage. Board the sub, work the mission, and either head home with salvage or lose it all if the voyage fails. There's no website gameplay — everything happens with commands typed straight into Twitch chat.
The Voyage

A voyage is a single, standalone run — it starts when the host opens boarding and ends when the sub either docks successfully or is declared a failure. Nothing carries over between voyages except what you salvage.

  1. 1Boarding — the host opens the voyage. Anyone in chat can join by paying the boarding fee and picking a profession.
  2. 2Underway — the host departs the sub. Crew work three mission tracks at once (Military, Science, Navigation) using in-game actions, fueled by songs played during the show.
  3. 3Docking — at the end of the show the host docks the sub. If all three mission tracks are complete, the voyage succeeds and everyone's salvage sells for Sawpoints. If not, the mission fails and everything gathered that voyage is forfeited.
A voyage that's left running too long is automatically declared a failure as a safety net — the host should always dock before ending the stream.
The Ocean Map

The host can optionally set each voyage in a named ocean region — a bit of flavor and setting, purely cosmetic (it doesn't change depth zones, what spawns, or the odds of anything). Every region the crew has ever explored is tracked on the public Ocean Map, alongside how many voyages (and how many successes) each one has seen.

Voyage Themes

Unlike ocean regions, a voyage theme (host-assigned at creation, default: none) actually changes what's down there — themed creatures show up more often once the crew reaches the deepest depth zone. Some themed voyages go further: the host can configure a chain of one or more guaranteed boss encounters that fight it out at max depth the moment the crew arrives, fought with the normal !sub hunt/!sub scan commands. Clear the whole chain and a treasure chest creaks open — crack its combination (2-4 digits, host-configurable) with !sub crack (Mastermind-style "locked/loose" hints, shared guesses across the whole crew) to split a Sawpoints reward and award an exclusive 1-of-1 item to whoever lands the winning guess. Track guesses and coordinate the crew's deductions on the Crack the Chest page.

Boarding & Costs

Boarding costs Sawpoints (Bonus SP is spent first, then regular SP). The fee scales up as the sub racks up more successful voyages over time — the crew's reputation (and the cost of a seat) grows with every successful run. Subscriber and VIP discounts stack:

DiscountAmount
Twitch Subscriber10% off
AiKillsBand.com VIP10% off
Both (stacked)20% off

Missed the boarding window? You can still board late after the sub departs, at a markup — the host can also close late boarding entirely for a given voyage. Exact costs are set per voyage by the host and shown with !sub status.

Most in-voyage action costs are covered by Action Points (AP) first, if any are banked, then Bonus SP, then regular SP — AP is earned just by playing (songs, listens, hunts, and more) and exists purely to cut down how much Sawpoints a voyage actually costs you. Boarding fees and Auction House purchases are the exception — both are Sawpoints-only (Bonus SP first, then SP) and can't be covered with AP.

Choose Your Profession

Pick a class when you board with !sub board <class>. Most actions are open to everyone regardless of class, and working in your profession earns full credit toward your rank — working outside it still counts, just at 25% weight (10% for Historian's log/review/rate). You can switch classes mid-voyage with !sub class <class> for a small cooldown-gated fee — except Cook, which can only be joined at boarding, and whose !sub cook/!sub bake commands only work for the crew member actually holding that class.

⚔️
Military
!sub hunt — fight exotic marine life summoned by songs. Winning harvests the creature for salvage and advances the Military track. Hunting a creature that shares your class gives a small odds boost. Buy a "weapon" bait from the Store (e.g. Rusty Cutlass, Loaded Cannon) and arm it to hit an active depth-5 boss harder on your next landed swing.
!sub board mil
🔬
Science
!sub fish and !sub scan — gather materials and analyze creatures to reveal their stats. Both advance the Science track. Materials have a rarity (common/uncommon/rare/legendary) that sets how likely they are to turn up, independent of their SP value. Science-only !sub bioheal mid-boss-fight draws on the guardian's own biochemistry to patch the hull without spending materials — a 10-minute cooldown and an escalating Sawpoints cost keep it a supplement to !sub repair, not a replacement.
!sub board sci
🧭
Navigation
!sub steer — push the sub into darker, deeper water. Advances the Navigation track and unlocks tougher creatures worth genuinely more salvage — but deep water is dangerous, and a lost fight down there hits the hull harder. Navigation-only !sub map (small AP/SP cost) banks safe-passage charges that soften — not erase — that extra risk on the next few deep-water hunt losses. Mid-boss-fight, !sub vibe has a 50/50 chance to pacify the guardian and freeze !sub hunt against it crew-wide for 1-5 minutes — a breather for repairs, at a cost that climbs each time it lands and a 20-minute lockout afterward.
!sub board nav
📜
Historian
!sub log, !sub review, and !sub rate — chronicle the voyage instead of fighting for it: log noteworthy events, write a review of a crew member's run, or rate the current song 1-10 (up to 2 decimal places). All three are free — no AP/SP cost — but naturally rate-limited (one review per crew member, one rating per song), which makes Historian the slowest track to rank up even at full credit. A ranked Historian's discount and salvage bonus benefit the whole crew, and stack across multiple Historians, up to a cap. Support-class slots (Historian + Cook combined) are limited: need 3 other crew for the first slot, +1 more every 10 crew after that.
!sub board hist
🍳
Cook
!sub cook and !sub bake — Cook-only commands nobody else can use, each costing AP (then SP) like most other actions. !sub cook consumes a few held fish (actual fish only, not raw materials — the catalog flags which is which) to mint bonus AP for the whole crew, at a deliberately lossy rate so it's never just free money over banking the fish for salvage. !sub bake turns a held rare or legendary fish into a dessert worth more SP, with the bonus scaling from 1.3x at Squab up to 2x at Admiral — and separately has a rank-scaled 20-90% chance to also mint a bonus copy of the source fish straight into the Auction House, on top of the normal dessert. Unlike every other class, Cook can only be joined at boarding — no switching into it mid-voyage — and shares Historian's support-slot pool.
!sub board cook
Ranks & Perks
Squab → Deckhand → Specialist → Officer → Chief → Master Chief → Commander → Admiral

Ranks are earned per class from XP. Check yours with !sub me.

Chief and higher ranks get an escalating Military hunt win-chance edge plus a bigger boarding fee discount for that class. Commanders and Admirals also get a personal critical-hit edge while hunting.

Historian ranks work differently: instead of personal combat perks, ranked Historians reduce boarding fees and boost salvage payouts for everyone aboard, stacking with other Historians up to a 15% cap on each.

Cook rank sets your !sub bake payout — the dessert value bonus climbs from 1.3x at Squab to a flat 2x at Admiral, one rank one step at a time. A Rare-fish dessert also has a rank-scaled chance (5% at Squab, up to 20% at Admiral) to turn out "super unique" — Legendary instead, with an extra 1.5x value bonus on top. Separately, every bake also rolls a rank-scaled 20% (Squab) to 70% (Admiral) chance to mint a bonus copy of the source fish into the Auction House — the Cook spec tree's Second Serving node can push that up to a hard 90% cap.

Working the Voyage

Once underway, boarded crew spend a small amount of Sawpoints (or Action Points, if any are banked) on each action to push the mission forward:

Songs fuel the crew — and summon the deep. When the host logs a song with !sub song <title> by <artist> <twitch-username> <link> (use (NO-TWITCH) in place of the username if the artist has none), it mints Action Points (AP) for every boarded crew member (spent before Sawpoints on any action) and has a chance to summon an exotic creature from the depths, generated deterministically from that specific song — the Encounter Overlay and admin panel both show which song (and artist, if given) surfaced it. Deeper depth zones (reached by steering) summon tougher creatures worth genuinely more salvage — but a lost fight against something from the depths chips the hull harder.

The artist of the song can talk back with !sub songinfo <message>. Verified by matching Twitch username against the song's artist tag, they can post up to 3 "Artist Says" messages per play (shown on that voyage's Voyage Log page) — no need to be boarded crew. Each message also mints some of the crew's prepared repair materials (see below) into the shared bank — a full roll on the 1st message, 25% less on the 2nd, 50% less on the 3rd — a bit bigger if the artist happens to be boarded crew too.

Boarded crew can prepare repair materials with !sub passive components. Any class can use it (Navigation gets a cost discount and a bigger yield) on a per-crew-member cooldown plus a short shared cooldown so multiple crew can't spam it back-to-back. It only stockpiles raw materials into a pending pool, not the shared bank directly — only the song's verified artist can mint that pending stock into the bank !sub repair spends from, via !sub songinfo. Refuses (without charging) once the pending pool hits its cap — meant as a buffer so a hard-hit hull between songs doesn't leave everyone standing around waiting for the next mint.

React to the music with !sub listen <comment>. Anyone aboard can leave one reaction per song — it's a 50/50 coin flip whether it mints a small amount of bonus AP (1 up to the voyage's listen cap), but every comment gets logged as part of that song's marine discovery record either way. Made a typo? Re-run the command once to fix it (the AP coin flip isn't re-rolled). Missed the window before the next song started? !sub listenlast reacts to the previous song instead. !sub rate/!sub ratelast follow the same once-per-song-plus-edit rules and roll the same 50/50 AP coin flip, just capped at half of listen's AP.

Once a mission track is complete, its payouts taper off. You can keep fishing or hunting after Science/Military hit their target — it still works and still nets salvage — but the payout drops to about half. It's more efficient to spread effort across all three tracks than to grind one past its goal.

Heading to Port — or Not
✅ Mission Success

All three mission tracks complete by the time the host docks. Every crew member's salvaged loot sells for Sawpoints, paid straight to your balance.

💥 Mission Failure

The sub docks with any mission track incomplete. All salvage gathered that voyage is forfeited — nothing sells, nothing carries over. Boarding fees are not refunded on a failed voyage.

If the host has to cut a voyage short before it resolves, they can !sub abort it instead — boarding fees are refunded and nothing is forfeited.
The Auction House

Every successful voyage's salvaged fish and materials also restock a house-owned Auction House — a between-voyage way to spend Sawpoints.

Outbid? Your Sawpoints are refunded automatically the moment someone tops your bid. Every open auction and every claimed exclusive item is visible on the public Auction House page.
The Living Sub

The sub itself persists across voyages — its hull, components, and banked raw materials all carry over, win or lose the mission tracks isn't the only thing at stake.

Hull hitting 0 mid-voyage is an immediate Sub Destroyed failure. On any failed voyage, components and banked materials wipe and hull resets to full for next time — but your class ranks always survive.

!sub feed <fish # or name> <food-code>Feed an owned Aquarium fish once per day with purchased food for XP.

Stacking all three, level 1 to 100 can drop from ~3 years down to roughly a year for a heavily engaged, top-ranked player — none of it can be farmed off-stream. Leveling up can promote a fish's rarity (common→uncommon guaranteed at level 10; uncommon→rare, rare→legendary, and rare/legendary→mythic are increasingly rare rolls at higher levels, with level 100+ costing noticeably more XP per level than below it).

Costs, cooldowns, and mission targets are set per voyage by the host and can change from stream to stream — !sub status always reflects the current voyage. AP = Action Points, SP = Sawpoints. Paid actions spend AP first (if listed), then SP. Bonus Sawpoints (BSP) can't be used for any of these — BSP is cosmetics-only, spendable on Decorations/Home Furnishings in the Store.
Sawpoints for entertainment purposes only — not real gambling.
