Act Dead or OOF Sea Knife
The Sea Knife is the first Act Dead or OOF gamepass anyone watched go on sale in real time. It was listed on July 30, 2026 at R$0 and not purchasable, sat there for three days, then flipped to R$259 and on sale on August 2, 2026 — the same day the Trident arrived. Its official description is “*Limited Time Tool for SUMMER EVENT*”.
The price history, step by step
Unlike the four original passes, which have been at fixed prices since July 19, 2026, the Sea Knife has a documented two-step history on the public gamepass record:
- July 30, 2026 — R$0, not for sale. The pass appeared on the listing but could not be bought. This was the first monetisation change since the game launched on June 22, 2026.
- August 2, 2026 — R$259, on sale. The price and the for-sale flag both changed, three days after the summer update renamed the game.
That gap is itself informative: 79studios stages event items on the store before switching them live, which is worth knowing if you want to spot the next one early. We track the gamepass listing every twelve hours and log changes on the updates page.
What is still undocumented
- Its effect in a round. No stat, no buff, no drawback is stated. The Scythe listing proves 79studios does spell out effects when there is one.
- Whether it is Hunter-only or usable by mannequins. Not mentioned.
- The end of the “limited time” window. No date published anywhere.
- Why it was priced at R$259. It does not line up with any existing pass tier.

Where it sits among all six passes
The summer event took Act Dead or OOF from four gamepasses to six, and roughly doubled the cost of owning everything:
- Trident — R$499 and x2 Permanent — R$499 (joint most expensive)
- Sea Knife — R$259 (this page)
- Scythe — R$139, x2 Yen — R$99, x2 Vote — R$67
Full set: R$1562 today versus R$804 in July. Run your own numbers on the value calculator, or read how the passes rank against each other in the tier list.
The cheaper way into the event
If you want a summer event item and R$499 is too much, the Sea Knife is the smaller bet — but it is still a bet, because neither tool has a published effect. We rate it C — unproven and will rewrite this section the day 79studios says what it does. New to the game and unsure where Robux goes furthest?

Sea Knife questions
What is the Sea Knife in Act Dead or OOF?
The Sea Knife is a gamepass that first appeared on the Act Dead or OOF store page on July 30, 2026 at R$0 and flagged not-for-sale. It went live at R$259 on August 2, 2026. Its official Roblox description reads "*Limited Time Tool for SUMMER EVENT*", tying it to the game's summer event.
Is the Sea Knife on sale now?
Yes. It sat unpurchasable at R$0 for three days after being listed, then switched to R$259 and on sale on August 2, 2026 — the same day the Trident (R$499) was added. Both changes are visible in the public gamepass price history for the game.
How much does the Sea Knife cost?
R$259, a one-time purchase. That places it in the middle of the range: more than the Scythe (R$139), x2 Yen (R$99) and x2 Vote (R$67), but well under the R$499 charged for the Trident and x2 Permanent.
What does the Sea Knife do?
79studios has not published its in-round effect. The listing is one line of event branding with no stat, no buff and no role restriction — unlike the Scythe, whose description openly states a "-5% Speed Boost when Equipped!" trade-off. There are no patch notes for the summer update either, so any specific ability you see quoted elsewhere is guesswork.
Is the Sea Knife worth buying?
With no documented effect, the honest answer is that you are buying availability rather than a known benefit. It is the cheaper of the two summer tools, so if you want one event item without spending R$499, it is the lower-risk pick. If you want guaranteed value per Robux, the passes with stated effects remain the better spend.
