The Alien's Revenge event triggers on Night 3, when UFOs crash near the campfire. Collect 5 Alien Batteries from Alien Outposts, Ponds, or Drops, then deliver them to the Command Ship to repair it and board the Mothership. Clear three guarded rooms using Alien Commander and Alien Scout corpses to unlock doors, defeat the final wave, then claim the reward chest and exit through the Earth teleport door to complete the event.
The aliens are back in 99 Nights in the Forest, and this time they've brought a flagship with them. The Alien's Revenge update adds Alien Outposts scattered across the map, a repairable Command Ship, a full Mothership raid with new alien-tech loot, and a brand-new playable class. So, to help you complete this event, this guide covers every step of the update, all the ways to farm Alien Batteries, the Mothership raid itself, and every reward on offer.
How Do You Start the Alien's Revenge Event in 99 Nights in the Forest?
The Alien's Revenge event begins automatically on Night 3, the same trigger point as the previous Aliens event. A cutscene plays showing multiple UFOs crashing near the campfire. Once the cutscene ends, your first objective is to repair the Command Ship sitting among the wreckage by gathering 5 Alien Batteries.
Alien Batteries are green cylindrical items found on Alien Outposts scattered across the map. If you have a map item, Alien Outposts will show up as marked locations, making it significantly easier to plan your route before heading out.
How Do You Repair the Command Ship in 99 Nights in the Forest?
Repairing the Command Ship requires collecting 5 Alien Batteries from anywhere on the map and depositing them into the ship's open hood near the campfire. There are four distinct ways to find batteries, each with a different risk and effort level.
1. Alien Sites: These function like a passive loot drop. An alien chest and battery sit underneath the structure with no mobs guarding them. You can walk up and collect both without fighting anything.
2. Alien Outposts: The more common outpost type, featuring a large tower guarded by multiple alien mobs. You need to clear out the guards first, then climb to the top of the tower to collect the battery and alien chest.
3. Alien Ponds: Look for green-colored mutated ponds across the map. Fishing in these ponds has a chance to fetch Alien Batteries directly, making them a useful source if you're already fishing for other resources.
4. Alien Drops: These are blue-colored launch pads. Defeat alien mobs and bring 3 corpses to the pad. Once all three are submitted, a green light shines over the pad and replaces the corpses with an alien chest and battery as a reward.
Once you've gathered all 5 Alien Batteries, return to the Command Ship near the campfire and place them in the open hood. After all 5 are deposited, the ship repairs itself, lifts off the ground, and a green light beam shines underneath it. Walk into the green light to start levitating upward. This is how you board the Command Ship.
How Do You Complete the Alien's Revenge Event?
Once aboard the Command Ship, you'll find it crawling with alien NPCs. The most common enemies are Alien Engineers (green, melee damage) and Alien Troopers (purple, ranged damage). Clear these out as you move through each section.
The enemies you specifically need to target and collect corpses from are:
- Alien Commander (orange, ranged damage)
- Alien Scout (small blue, melee damage)
Their corpses are required to open the doors blocking your path deeper into the ship. Each door has a face-scanning mechanism that needs one of these specific corpses to unlock. Bring the right corpse to the right door to progress.
Repeat this process to clear all three side rooms on the ship. Once cleared, you'll reach the main room on the next floor, where you need to defeat approximately 5 more aliens. Defeating them unlocks the large chest, which drops high-tier loot such as the Alien Shotgun, Dissolve Ray, and various blueprints.
After looting the chest, head to the green door with the option "Teleport to Earth" in the same room. Walking through it completes the Alien's Revenge event and returns you safely to the forest.
What Are the Rewards for Completing the Alien's Revenge Event?
Completing the event rewards high-tier alien loot from the central chest, including the Alien Shotgun, Dissolve Ray, and various blueprints for crafting alien-tech gear. Beyond loot, the event also introduces a brand-new playable class and a set of exclusive badges with cosmetic rewards.
How Do You Get the Alien Scientist Class?
The Alien Scientist is a new class added with this event, purchasable for 600 Diamonds. It comes with a strong starting loadout containing 1x Alien Shotgun, 1x Dissolve Ray, 1x Raygun and a perk tree centered on converting low-HP enemies into Essence.

Frequently Asked Questions (FAQs)
The event triggers automatically on Night 3, the same point in-game as the original Aliens event. A cutscene plays showing UFOs crashing near the campfire, after which you can begin collecting Alien Batteries to repair the Command Ship.
Alien Sites are the safest and fastest source since the battery and chest sit unguarded with no mobs to fight. Fishing at Alien Ponds can yield batteries while you're already gathering other resources. Alien Outposts and Alien Drops require combat but are more common across the map, making them reliable options.
No. The Alien Scientist is an optional purchasable class for 600 Diamonds and is not required to participate in or complete the event. Any class can repair the Command Ship, raid the Mothership, and claim the event badges.
