Command Ship UFO

The Command Ship UFO is the alien ship you board during the Alien's Revenge event in 99 Nights in the Forest. It is crawling with alien NPCs. The most common are Alien Engineers (green, melee damage) and Alien Troopers (purple, ranged damage), and you clear them out as you move through each section.

Two other enemies are the ones you actually need to target: the Alien Commander (orange, ranged damage) and the Alien Scout (small, blue, melee damage). Their corpses are required to open the doors that block your way deeper into the ship. Each door has a face-scanning mechanism that needs one of these specific corpses, so you bring the right corpse to the right door. You repeat this to clear all three side rooms.

After the side rooms, you reach the main room on the next floor and must defeat roughly five more aliens. Doing so unlocks the large chest, which drops high-tier loot such as the Alien Shotgun, the Dissolve Ray and various blueprints for crafting alien-tech gear.

Once you have looted the chest, go to the green door in the same room with the option "Teleport to Earth". Walking through it completes the Alien's Revenge event and returns you safely to the forest. Besides the loot, the event also introduces a new playable class and a set of exclusive badges with cosmetic rewards.
