The official site lists the current build as 4.0.0 with an update date of 24 September 2026. The story moves to 1930s England, around the Arthurian play "Fate Hangs by the Blade's Tip" and the awakening ruins of Camelot.

Reverse: 1999 4.0 Overview
Reverse: 1999 4.0 release date and new characters
The official site shows version 4.0 "The Gatekeeper" updated on 24 September 2026 at build 4.0.0, and its keyword list names the new characters for this cycle: Huntsworn Lilia, Drake and Gwendolyn. A new Psychube tuned for the buffed 37 shipped in the same patch.
Story and setting
In the main cruise story, Vertin and Lilia's group arrive in 1930s England, where Arthurian legend still circulates and a play titled "Fate Hangs by the Blade's Tip" is about to open. Nearby, the Camelot ruins that have slept for a thousand years wake up.
Reverse: 1999 Huntsworn Lilia Mechanics
How the weak-point phase works
Huntsworn Lilia is the grown-up form of the launch character Crossbow, and she works as the core damage dealer for the Insight archetype. When she enters the weak-point piercing phase, she can spend Insight points to strike rapidly: every second attack becomes an AoE attack. Before the phase ends she can also fire a finisher, and that finisher scales with the number of actions your side took during the phase .
Two things follow from this. Her ceiling depends on team action count, so supports that act often raise her finisher damage. And because the AoE upgrade follows a fixed rhythm, wasted actions inside the phase cost you real damage.
Using the reset-to-origin effect
The Insight archetype also lets her cast an Insight skill for free through the reset-to-origin effect, which raises her finisher damage. In practice, hold that free cast for the back half of the phase so the finisher inherits the fullest action count.
Why the buffed 37 matters
The 37 that received the Reverie upgrade is Lilia's best partner, lifting both burst damage and support output. That makes 4.0 a two-core patch: Lilia supplies the main damage, and the buffed 37 supplies the buffs and secondary output. Missing one of them clearly drops the team a tier.
Reverse: 1999 4.0 Insight Team Setups
| Team | Setup | Where it works | Rotation notes |
|---|---|---|---|
| Standard Insight | Huntsworn Lilia + buffed 37 + generic support + sustain | Mane Bulletin, Spotlight Flashback | Spread 37's buffs first, then farm action count inside the weak-point phase |
| Free-cast route | Lilia + 37 + reset-to-origin slot + sustain | Long stages | Save the free Insight cast for the back half and pair it with the finisher |
| Bridge build | Lilia + generic support + sustain | Standard stages | Without 37, protect survival first and accept a weaker finisher |
Generic support options include Little Rianon, and generic sustain options include Martha, Riddles or J . All three sustain picks already exist in most accounts, which keeps the patch cheap to enter. All three sustain picks are broadly usable, so no new character needs building just for this version.
Reverse: 1999 4.0 Rewards and Resource Planning
Version 4.0 reward list
The official reward list includes 40 free pulls, a guaranteed new six-star, a Reverie upgrade item exclusive to 37, a new Psychube tuned for the buffed 37, and a large batch of upgrade materials.
The guaranteed new six-star is the easiest item to overlook. It ensures the six-star you receive is one you do not own, which matters most for returning players. If you are missing a key component, spend that slot first.
Priority order
| Priority | Item | Why |
|---|---|---|
| High | Claim the 40 pulls and the guaranteed new six-star | Zero cost, and the guarantee expires with the patch |
| High | The 37 Reverie upgrade item | Completes the second core of the Insight team |
| Medium | New Psychube | Tuned for the buffed 37, take it with surplus |
| Low | Stockpiling generic materials | Never scarce, and the current team matters more |
For returning players this is a re-entry window: the guaranteed six-star patches a missing slot while the upgrade item brings 37 up to usable. Our GameHub guides archive tracks which reward types return each patch, so you can tell a one-off bonus from a rotating one before spending. For new players, push the main story far enough to unlock the endgame modes before investing, otherwise a finished team has nowhere to play.
Reverse: 1999 4.0 Practical Tips and Mistakes
- The weak-point phase runs on a two-attack, one-AoE rhythm. Do not insert dead actions that break it.
- Before the finisher, check how many actions your side already spent in the phase. More actions, more damage.
- Hold the free Insight cast from reset-to-origin until the back half of the phase.
- Without the buffed 37, stop stacking damage on Lilia and invest in survival and action frequency instead.
- The guaranteed new six-star has an expiry. Use it early rather than saving it for a hypothetical better character.

- Palworld v1.0.5 Tower Boss Order Guide: Elements, Counters and Squad Choices
Palworld's v1.0.5 patch (2026-09-15) only fixed texture loading, so what actually shapes tower runs is the 1.0 release itself: the boss count expanded from 7 towers in early access to 9, the level curve runs from 10 all the way to 80, and the new Sunreach sky islands and World Tree finale sit at the end of it . Clearing towers is less about raw investment than about picking Pals that exploit each boss's element.
- Reverse: 1999 Version 4.0.0 Second Half Guide: Drake, the October 15 Banner Swap and Free Rewards
Reverse: 1999 has moved into the second half of version 4.0.0, and the banners swap on October 15: Drake arrives as a new standard six-star Beast character, while a pick-your-own rate-up runs with Quniang, Liangyue, Nana, Lucy and Nodica selectable . The first half's limited SP Crossbow banner closes at the same point, so October 15 is a clean dividing line.
- Love and Deepspace Xavier Birthday Guide: Wish Upon This Moment Banner Window
Love and Deepspace's Xavier birthday event is live, and the birthday five-star Memory is obtainable from 2026-10-11 at 05:00 to 2026-10-18 at 04:59 (source: official birthday calendar and birthday Memory announcement, 2026-10-08). The window is only seven days and it is a single-character banner rather than a pooled one, so the budget is easier to plan, provided you count your tickets and diamonds before you start pulling. The single target is the main advantage: there is no risk of boosting the wrong Memory and no need to compare three candidates.

Honkai: Star Rail's 4.6 Planar Fissure event is live, and Planar Ornaments drop double rewards for the duration . The doubled runs are limited and do not reset during the event, so the goal is not farming more but spending the limited runs on the two worlds your roster actually needs.
- Genshin Impact 7.1 Imaginarium Theater Guide: Ice, Hydro and Anemo Stacking
The October 2026 Imaginarium Theater rotation locks the playable elements to Ice, Hydro and Anemo, and its core mechanic grants one stack of Frost Benediction whenever your party triggers Swirl, with each stack adding 80% Swirl damage and 12% crit damage up to 3 stacks . So the rotation is not about raw damage but about Swirl frequency, getting the blessing to full stacks as fast as possible.

The Wuthering Waves 3.7 Tower of Adversity refreshed on October 13, and this rotation cuts Havoc resistance on the left tower's fourth floor, which clears the way for Havoc teams. The mid tower remains the hardest part of the cycle, with Sunmoon, Cartethyia and Phrolova squads still carrying it, Zhanfei usable, and Galbrena needing Qiuyuan to reach full shape. If you only need the rewards, the side towers auto-clear and your stamina belongs to the mid tower.

If you only want the Polychrome, getting all three rooms to S is enough, because the reward gate is the S rank and not the total.
