How to Repair the UFO in 99 Nights in the Forest (All 5 Alien Battery Locations Guide)

The UFO is one of the biggest side objectives in 99 Nights in the Forest, but you won’t be able to complete it right away. After it crashes into the map, you’ll need to search for Alien Outposts, complete their challenges, and collect five Alien Batteries to restore the ship. Along the way, you’ll also earn useful alien-themed rewards that can help with later fights. If you’re wondering when the UFO appears, where to find Alien Batteries, and what happens after repairing it, here’s everything you need to know.

When Does the UFO Spawn?

The UFO does not appear at the start of your run. Instead, it crash lands on Day 3, which is also when Alien Outposts begin appearing across the map. There’s no reason to search for either before Day 3 since they won’t exist yet. Once they become available, locate the UFO first because it contains a helpful scanner that marks the locations of every Alien Outpost, making exploration much easier.

How to Get All 5 Alien Batteries

You’ll need a total of five Alien Batteries to fully repair the UFO. There are several ways to obtain them during your adventure.

1. Complete Alien Outposts

Alien Outposts are the main source of batteries. Each outpost gives you a different objective before rewarding you with an Alien Battery. The tasks are randomly selected, so they may not always be the same between playthroughs. Some common objectives include:

• Defeat nearby aliens.
• Carry alien bodies onto the scanner platform.
• Scan an alien face by dragging an alien body to the scanner.
• Complete other small interaction-based objectives.

After finishing the objective, you’ll receive:

• 1 Alien Battery
• An Alien Chest containing bonus rewards

These chests can include items such as:

• UFO Scrap
• Alien weapons
• Other special loot

Because of these extra rewards, it’s worth clearing every outpost you find, even after collecting enough batteries.

2. Search Chests Around the Map

Not every battery comes from an outpost. Regular treasure chests found while exploring also have a chance to contain an Alien Battery. If you’re already traveling between objectives, make sure to open every chest you come across since you might save yourself an extra trip to another outpost.

3. Fish in Lakes and Ponds

Fishing can also reward Alien Batteries. Although the drop isn’t guaranteed, players have reported finding batteries while fishing in small lakes and ponds throughout the map. If you’re carrying a fishing rod, it’s worth spending a few minutes trying your luck whenever you pass a body of water.

Return Batteries to the UFO

After collecting a battery, head back to the crashed UFO and install it immediately. Each battery powers up the ship a little more, and the onboard scanner updates after every deposit. This helps you identify which Alien Outposts you still need to visit, making the remaining search much easier. Repeat the process until all five battery slots are filled.

What Happens After Repairing the UFO?

Once you’ve installed every Alien Battery, the UFO becomes operational and its entrance opens. Inside, you’ll face multiple hostile aliens in a combat-focused area, so it’s a good idea to prepare before entering. Bring the following:

• Fully loaded weapons
• Plenty of ammunition
• Medkits for healing
• Strong melee weapons as backup

The enemies inside deal much more damage than normal, so don’t rush through the rooms without healing when necessary.

How to Progress Inside the UFO

Clearing the first group of enemies is only part of the challenge. Several doors inside the UFO require you to scan the correct alien type before they’ll unlock. Each door is linked to a specific alien color, meaning you’ll need to defeat the appropriate enemy and place its body into the matching scanner.

Using the wrong alien won’t open the door, so pay attention to the scanner’s requirement before dragging a body over. As you continue deeper into the ship, you’ll repeat this process while fighting additional alien groups until you’ve explored the entire UFO.

Repairing the UFO in 99 Nights in the Forest is one of the longest activities available after Day 3, but it’s also one of the most rewarding. By completing Alien Outposts, searching chests, and occasionally fishing for extra batteries, you’ll eventually collect all five Alien Batteries needed to restore the ship. Once it’s repaired, you’ll unlock a combat-heavy alien dungeon filled with unique loot and new challenges, making it a worthwhile objective for players looking to experience everything the game has to offer.
