Our take on Alien Investigator

The bounce point arrives when investigation requires coordinating with other players: the game centers on online teams of up to four and voice chat. Players expecting a solo case-solving experience may hit that wall before the evidence-gathering tools or alien-identification systems become relevant.

What is Alien Investigator?

Alien Investigator is an online co-op horror game for up to four players.

Teams investigate alien encounters, collect evidence, identify extraterrestrial types, and try to survive each mission. The game includes 18 alien types based on reported stories, seven evidence categories involving events such as crop circles and abductions, and equipment including a walkie-talkie and ultraviolet light. Tools can be upgraded as investigator levels increase. Missions feature random events, while successful investigations provide experience and money when the alien is identified and the team survives. Voice chat supports coordination between players. The vendor also describes planned additions, including more alien types, maps, content, and enigmas.
