Idle Area 51 is a simulation game developed by PlaySide Studios, available for free on Android. In this game, you are in charge of a secret desert facility where you have to salvage as much alien tech as possible from the downed UFO and research it. The game starts with a small operation, and you have to unlock the secrets of alien biology, UFO construction, high-powered laser weaponry, and interstellar travel to gain more funding from the government department overseeing everything.

To maximize the efficiency of your facility, speed up your processes, buy more vans, get more salvage, increase your research stations, train your workers, and grow your operations. However, you need to work fast and keep an eye out for the little green guys, wear your tinfoil hats, and expect a visit from the Guys in Black. Start a misinformation campaign to throw the public off the scent, watch out for raids on your facilities, and upgrade your operations with goodies from interplanetary Star Gates and mysterious Quasars.

Overall, Idle Area 51 is an engaging game with a unique concept. It offers exciting challenges and various opportunities to upgrade your facility while keeping an eye out for the little green guys.
