99 Nights in the Forest: The Aliens Revenge — Alien Scientist Class, Mothership Raid, Battery Locations & Badges (June 2026)

Last Verified: June 30, 2026. Every stat, quest step, badge name, location, and code below is sourced to a primary write-up: Sportskeeda's Aliens Revenge patch notes and dedicated Alien Scientist class guide (June 27, 2026), Pocket Tactics' 99 Nights update tracker, Pro Game Guides' Aliens Revenge event guide and the two companion guides ("All 5 Alien Battery Locations" and "How to Raid the Alien Mothership"), and the official fansite update log at 99-nights-in-the-forest.com. Developer/studio attribution is confirmed against the Roblox DevForum Creator Spotlight for Grandma's Favourite Games. Anything not confirmed by at least two of those sources is flagged in-line.

The two-week update cadence held. 99 Nights in the Forest shipped The Aliens Revenge on Saturday, June 27, 2026 — the direct follow-up to The Forest Wakes Up (June 13). The framing on the official patch notes reads clean: "The aliens haven't taken kindly to your meddling… and they're back with a vengeance." That's a story-mode punch back at the Alien Outposts players had been raiding all June, and it's the first Roblox 99 Nights patch to add a full end-of-event raid encounter with keyed side rooms, a stated boss target, and a themed cosmetic. If you logged in Saturday night and got yanked into a UFO cutscene on Night 3 without knowing what happened, this is the full breakdown.

TL;DR — What Shipped in The Aliens Revenge

• Released: Saturday, June 27, 2026 (Sportskeeda patch-notes datestamp; Pocket Tactics explicitly names the weekday). Follows the studio's established two-week cadence out of The Forest Wakes Up (June 13).
• New class: Alien Scientist — a 5-star class sold in the Classes shop for 600 Diamonds. Starting tools: 1× Alien Shotgun, 1× Dissolve Ray, 1× Raygun.
• Three-level perk tree centred on Essence: Lv. 1 dissolves sub-10%-HP enemies into Essence + +4 Sack Space; Lv. 2 raises the threshold to 15% and lets Meat? Sandwiches drop on dissolve; Lv. 3 makes Essence also grant sprint speed.
• Event trigger: automatic on Night 3. A cutscene plays showing multiple UFOs crashing near the campfire — no manual quest pickup required.
• Quest chain: collect 5 Alien Batteries from four different location types → deposit them in the Command Ship's open hood → ride the green tractor beam up into the Mothership → clear three keyed side rooms → beat the main-room wave → take the reward chest → Earth teleport door exits the event.
• Three new badges: Engineering (complete the Command Ship repair), Mutiny (defeat the Alien Command Center), Xenotech (enter every Command Ship side room in a single run).
• Two new enemy types named in the raid loop: Alien Commander and Alien Scout — their corpses are the door keys for the Mothership side rooms.
• Limited-time cosmetic: Alien Wolf Skin, available only for the duration of the event window.
• Active codes as of June 30, 2026: forestwakesup26, afterparty, and the chat-only code yay fishing. Redeem before Grandma's Favourite Games rotates them out for the next patch cycle.

The Night 3 Trigger — How the Event Starts

You don't need to visit an NPC or open a menu to start The Aliens Revenge. Per Pro Game Guides' launch-week event guide, "the Alien's Revenge event begins automatically on Night 3" — the game cuts to a scripted cutscene showing multiple UFOs crashing near the campfire, then hands control back with the world state changed. Alien Sites, Alien Outposts, Alien Ponds, and Alien Drops are now spawnable across the map, and the Command Ship shell has landed near your base.

Two practical consequences of the "automatic on Night 3" design:

• Any active run past Night 3 is on the event clock. Fresh lobby starts will always get the cutscene; a lobby that started before the patch and rolled into Night 4+ may not. If you were mid-run and don't see UFOs, exit to the campfire, restart the day cycle, and confirm the cutscene fires on the next Night 3.
• The event does not gate difficulty. Both Normal and Hard Mode fire the same trigger, which matters if you were pushing a Hard Mode Corruption run and want to know whether alien systems will collide with the corruption threshold. So far, no source has flagged Corruption-specific behaviour changes — treat Corruption prep as unchanged and layer the alien quest on top.

Alien Scientist — 5-Star Class Deep Dive

The Alien Scientist is the patch's headline unlock and the one bit of persistent progression you take out of the event. It sits at 5-star rarity in the Classes shop and costs 600 Diamonds, so anyone who's been banking Diamonds through the June cycle can afford it without needing to buy Robux.

Starting Loadout

Every run you launch as Alien Scientist begins with three alien-themed tools:

• 1× Alien Shotgun — close-range crowd control against the alien mob types the event pushes into your base.
• 1× Dissolve Ray — the class's signature weapon. Pairs directly into the sub-10%-HP dissolve mechanic to convert kills into Essence rather than corpses.
• 1× Raygun — mid-range single-target, useful for Alien Commander and Alien Scout target picks before their corpses become raid keys.

The Three-Level Perk Tree

Sportskeeda's dedicated class guide and Pro Game Guides' event guide both quote the exact level breakpoints, matching word-for-word:

• Level 1: "Get enemies under 10% HP to dissolve them into essence. Gain essence to increase your alien energy regen speed. +4 Sack Space." The +4 Sack Space alone is one of the strongest single-perk inventory buffs in the game — you effectively play with a bigger backpack from run 1.
• Level 2: "Dissolving threshold increased to 15%. Meat? Sandwiches have a chance to drop on Dissolve." Bumping the threshold from 10% to 15% widens your kill window on tanky mid-game enemies dramatically, and the passive food drop chips into your hunger management in the mid-Night stretch.
• Level 3: "Essence also gives sprint speed." Because Essence is generated on every dissolve and stacks into your Alien Energy regen loop, Level 3 turns the class into a mobility DPS — the more you kill low-HP targets, the faster you kite the next wave.

Class Fit & Verdict

Alien Scientist is best in high-mob-density scenarios — Alien Outpost raids and the Command Ship main room being the two clearest matches shipped this patch. It underperforms in single-boss encounters where nothing sits below the dissolve threshold long enough to farm Essence, since the class's whole loop depends on repeatedly pushing enemies below 10% (or 15% at Level 2). Solo players will feel Level 3 the most — sprint speed on kill is genuinely run-saving on tight campfire returns.

All Four Alien Battery Sources

The core loop of the event is getting five Alien Batteries back to the Command Ship. Per Pro Game Guides' battery-locations breakdown, four location types spawn batteries after Night 3, and each carries a different risk/reward profile:

The mix is deliberate: two low-risk paths (Sites and Ponds) let solo/low-level runs finish the event without needing to farm combat, while Outposts and Drops layer a raid-style option on top for coordinated groups that want the loot-chest side rewards. If you're aiming for the Xenotech badge (below), the fastest all-five-battery path is 3× Alien Sites + 2× Alien Drops — it doubles up on chest yield without needing the fishing rod loadout swap.

Command Ship & Mothership Raid Loop

Once you've hit five batteries, the raid opens. Pro Game Guides' Mothership-raid guide walks the sequence step-for-step:

1. Return to the Command Ship near the campfire. The ship spawns as a grounded shell once the Night 3 cutscene finishes.
2. Place all 5 Alien Batteries in the open hood. Each battery deposit is a fixed animation — worth doing between mob waves rather than mid-combat.
3. Ship repairs and lifts off. A green light beam shines underneath. Walk into the beam to levitate up.
4. Board the Mothership. You're now inside the alien flagship. Three side rooms are locked; each door needs an Alien Commander or Alien Scout corpse to open.
5. Clear the three side rooms. Farming Commander/Scout corpses is the gate — every door is a fresh corpse. Clearing all three in a single run is the Xenotech badge trigger.
6. Beat the main-room encounter. Approximately five aliens spawn as the final wave. The Alien Command Center is the boss target — killing it unlocks the Mutiny badge.
7. Claim the reward chest and exit through the Earth teleport door back to the forest.

Two subtle things the raid guide flags: Commander/Scout corpses have to be carried in (they don't stack in your inventory), so pushing the raid solo means running the "kill → drag → unlock" loop three times over. And the reward chest is after the main-room wave — dying in that wave forfeits both the loot and Mutiny credit for the run.

Every New Badge — Engineering, Mutiny, Xenotech

Three new badges shipped with the patch. The official fansite's update log gives the completion criteria in one line each:

• Engineering — complete the Alien Spaceship repair task. Deposit all 5 batteries and trigger the tractor beam.
• Mutiny — defeat the Alien Command Center in the main Mothership room.
• Xenotech — enter every Command Ship side room in one run. All three must be opened in the same raid; failed runs reset progress.

The badge design is stackable — a clean successful raid nets all three at once. Xenotech is the hardest to naturally collect because it forces the "farm three Commander/Scout corpses in the same run" behaviour, which a rushed solo player might skip if they only need to reach the boss room. If you're chasing achievement completion, plan for one purpose-built run where you take the long path.

Alien Wolf Skin (Limited-Time)

The event's exclusive cosmetic is the Alien Wolf Skin, available only during the event window. Neither Sportskeeda nor the fansite has published an explicit event-end date, so treat this like every other 99 Nights limited: obtainable now, gone at the next major patch. Given the studio's confirmed two-week cadence, the practical retirement date is on or around July 11, 2026 — when the next patch drops. Pocket Tactics explicitly flags July 11 as the predicted next-update window based on the established cycle.

Practical implication: if you want the skin, farm it this week or next. Don't assume it will roll forward into the next event the way permanent classes do.

Active Redemption Codes (June 30, 2026)

No launch-specific Aliens Revenge code has appeared in Pocket Tactics' tracker or the official fansite as of June 30. The standing code set from the previous patch cycle continues to work — verified against Pocket Tactics' codes tracker and the official fansite:

Redeem the two main codes from the campfire menu → Codes tab. The yay fishing chat-code is the only one gated behind an active fishing session, which is easy to combine with the new Alien Pond battery farming loop — cast at the pond, type the code in chat, collect. Two Diamonds for effectively zero effort.

Launch-Week Priority List

1. Redeem all three active codes before your first alien run. Front-loading Diamonds means you can buy Alien Scientist on the same login session that unlocks the event.
2. Buy Alien Scientist and take it into your first Night-3 event trigger. The +4 Sack Space alone is meaningful backpack economy for the battery-collection phase.
3. Push Alien Scientist to Level 3 in your first two or three runs. Sprint-on-Essence is the single most run-saving perk in the tree, and mob-heavy alien waves grind the perk tree fast.
4. Prefer Alien Sites and Alien Ponds for your first successful raid. Low-risk battery farming means your first Command Ship attempt has full HP and full inventory — reserve Outpost and Drop raids for the badge cleanup pass.
5. Chase Xenotech on a dedicated run. Farm three Commander/Scout corpses back-to-back on that attempt. Engineering and Mutiny will fall out naturally.
6. Grab the Alien Wolf Skin during this event window. The next patch is predicted around July 11, 2026. Skin availability likely ends there.
7. Don't retire your Hard Mode Corruption prep. Nothing in the Aliens Revenge patch notes rebalances Hard Mode — Corruption runs continue as before. Layer the alien quest into your existing Corruption strategy.

FAQ

When did The Aliens Revenge release?

Saturday, June 27, 2026. The Sportskeeda patch-notes article was published the same day at 18:18 GMT, and Pocket Tactics explicitly names the weekday in its update tracker.

How do I unlock the Alien Scientist class?

Visit the Classes shop from the campfire and spend 600 Diamonds. The class is 5-star rarity and starts each run with an Alien Shotgun, Dissolve Ray, and Raygun.

When does the alien event actually start in-game?

Automatically on Night 3. A cutscene plays showing multiple UFOs crashing near the campfire — no quest pickup required. If you started your run before the update, exit to the campfire and re-launch so the trigger fires cleanly.

Where do I find the 5 Alien Batteries?

Four sources: Alien Sites (unguarded — safest), Alien Outposts (combat-guarded structures), Alien Ponds (fishing), and Alien Drops (submit 3 alien corpses to the pad, which spawns a chest + battery). Any mix of the four totalling five batteries opens the Command Ship raid.

How do I raid the Mothership?

Deposit all 5 batteries in the Command Ship's open hood → step into the green tractor beam → clear three side rooms using Alien Commander and Alien Scout corpses as door keys → beat the final wave in the main room → take the reward chest → exit through the Earth teleport door.

What are the new badges and how do I earn them?

Three badges: Engineering (complete the Command Ship repair — happens automatically when you deposit all 5 batteries), Mutiny (defeat the Alien Command Center in the Mothership main room), and Xenotech (enter every Command Ship side room in a single run — all three doors, one run).

Is the Alien Wolf Skin permanent?

No. It's a limited-time exclusive tied to The Aliens Revenge event window. The next update is predicted around July 11, 2026 (Pocket Tactics), which is when the skin is expected to leave the event shop.

Are there any Aliens Revenge–specific codes?

No launch-specific code has surfaced on Pocket Tactics' code tracker or the official fansite as of June 30, 2026. The active carryover codes are forestwakesup26 (15 Diamonds + 3 random Flames), afterparty (15 Diamonds), and the chat-only yay fishing (2 Diamonds, typed during an active fishing session).

Who developed 99 Nights in the Forest?

Grandma's Favourite Games, a three-person New Zealand studio: Kieft ("Cracky4", game designer), Hufton ("ForyxeV", programmer), and Angland ("Viridial", environment and asset design). The studio's story is documented in the official Roblox DevForum Creator Spotlight.

What was the previous major update?

The Forest Wakes Up, released June 13, 2026. Aliens Revenge follows the studio's established two-week cadence out of that patch.
