UFO: Afterlight wiki
Advertisement

UFO:Afterlight has many events. For example, win the tutorial mission and the people will discuss the need of a military force. Not long after, communication officer will report that communication with Earth is lost. And when human meet the first alien faction, they will send a diplomatic message requesting alliance.

Events in Afterlight are both trigger and time based. Some events happens no matter what you do, like losing communication, and some events happen with a trigger, like meeting aliens. Difficulty does not affect the time between events.

Below is a list of events. Times are rounded to nearest 15 minutes interval. Because of game engine's imprecise timing, the actual trigger time may be off by a few minutes.

Rescue Martians after alliance, on Beastmen territory, Captured alien missions
Al icon event.pngHuman Robot Controlled Robot got controlled by Martian.

Note:

There's a type of mission call Counter Martian Appearance and Counter Expedition Landing. They appear when these factions appear in timed events, at areas slotted to be theirs but Human currently controlled. These missions are the same as territory defense missions. Aka in Counter Martian in Cherson you fight as if Martian force invade your land and not the martian base type.

If you let counter missions run out, that specific faction will own that land, and later on you have to fight on that faction's base map. To get the tagged event of raiding a specific faction's base HQ, you need to fight this base map and not the counter maps.

After alliance with Martian is on, on Beastmen territory, aside from Zephyria and Elysium mountain, will appear a type of mission called Rescue captured alien. The mission note clearly say what need to be done: team of 6 or less. Enemy type is Beastmen, with one Martian stay around the Beastmen. Meet it and it joins immediately. Win that mission and one Martian join roster. Win three and the missions are done, no longer appear. The order to join is: soldier, scientist, soldier/scientist.
