Chainers Sunken World — Tranquil Waters farmland and Season Pass V3
51.games opened The Sunken World for Chainers around July 30, 2026, adding the water farmland Tranquil Waters and Season Pass V3 under the same theme. Pre-sale pricing on the new land ($9.99, then $14.99) and the stated best price on the pass ($29.99) both hold only through August 2, 2026. If you still farm on browser or mobile, those few days are when early land and pass purchases lock in at the launch rates.
Background
Chainers is a free-to-play Web3 MMO from 51.games: customize Chainer NFTs, farm, craft, and explore with optional token layers. Day-to-day shop and season spending lean on CFB (soft currency inside the client). CHU is the ecosystem token for broader economy plans. Play spans Polygon, Immutable, and the Chainers sidechain, with discovery on Immutable Play.
Live-ops moved fast after the June anniversary window. Royal Celebration and Season Pass S1: Peacock Domination ran through June 29, 2026. Season Pass V2 followed in July with Infinity levels, CFB level buys, and Auto Collect tools (Crypto Games V2 coverage (opens in new tab)). On July 17, the studio also reworked reward pools and added Tier 4, with Tier 1 daily CFB payouts reported rising from 750 to 3,000 (Crypto Games reward-pool report (opens in new tab)). Sunken World is the next content beat in that monthly cadence, not a full client relaunch.
What happened
The Sunken World and Tranquil Waters
Per the official Chainers Discord announcement (mirrored in secondary reporting such as Blockchain Games Fun (opens in new tab)):
- The Sunken World frames Chavier’s first underwater expedition into the Chainersverse.
- Tranquil Waters is a new farmland type aimed at water creatures and flora not previously farmed.
- Pre-sale: Tranquil Waters at $9.99 through August 2, then $14.99.
- New animal: Common Otter Otto at 31.313 BioPoints. It produces shells and eats fish (Cute Fish cited as otter food in secondary coverage).
- New plot type: handmade Pool Plots in three rarity tiers: Reinforced (Uncommon), Stable (Rare), Engineered (Epic).
- New crop: sugarcane seeds.
- Opening expedition missions are live. Sunken World missions grant Season Pass XP.
- Finish the full 10-mission chain for new items plus a premium reward bundle.
- Six shop bundles are available, including limited-supply hero tiers.
The in-game calendar for this opening promo window is reported as July 30 to August 2, 2026.
Season Pass V3: Tranquil Waters
EGamers coverage of the V3 store post (opens in new tab) places Season Pass V3 under the Tranquil Waters brand at $29.99, billed as the studio’s best pass price only until August 2. That makes three passes inside roughly three months after S1 (Peacock Domination) and V2.
Launch posts reviewed for this article do not publish a full V3 reward table, main level count, or season end date. Do not assume S1’s 25-level map or V2’s two-day discount pattern still apply. V2 did change the chassis players still use: Infinity levels past the old level-28 stop, a single Golden Pass purchase for premium tracks, CFB spends to buy levels, Auto Collect, and Reclaim Everything after finishing levels (EGamers V3 context (opens in new tab)). Treat those as inherited systems unless the client shows otherwise for V3.
Who it affects
Players
Farmers who buy land or the pass before August 2 keep the launch prices cited above. After that date, Tranquil Waters rises to $14.99; the post-promo Season Pass price has not been stated in the sources we checked.
Mission-first players should run the Sunken World chain for Season XP even if they skip paid land. Otto, Pool Plots, and sugarcane change the merge and plot loop the same way peacock lines did in S1: new BioPoint targets and new inputs, not a separate game mode.
CFB still fuels shop, upgrades, and season acceleration. Reward-pool Tier 4 and higher Tier 1 payouts from mid-July change how much soft currency daily pools can pay; they do not replace checking live client rates before you spend.
Collectors and token participants
No new catalog collection contract is required for this beat. It is live-service content on existing Chainers infrastructure. Chainer NFTs and farm outputs can still touch Polygon, Immutable, or Chainers Chain depending on asset type. Check chain and contract before bridging or buying.
Treat CFB spends and CHU ecosystem messaging as progression context, not investment advice. Studio roadmap talk about a later CHU listing window belongs on the CHU token page, not in this season-pass purchase decision.

What to watch next
- August 2, 2026: end of Tranquil Waters pre-sale and V3 “best price” window (Discord + store posts)
- Full V3 reward table, level count, and season end date when Chainers publishes them (Chainers on X (opens in new tab), Discord (opens in new tab))
- Whether Infinity levels, Auto Collect, and CFB level buys behave the same as V2 inside the new pass
- Live reward-pool tiers after the July 17 overhaul (Crypto Games report (opens in new tab))
- Post-August land and pass sticker prices once the promo clocks out
Bottom line: If you want Tranquil Waters or Season Pass V3 at the launch rates, act before August 2. Otherwise start the Sunken World mission chain for Season XP and wait for an official V3 reward table before planning a full Golden Pass grind.
