The aliens have CRASH landed!! Salvage as much alien tech as possible from the downed UFO and take it to your super secret desert facility for research in Idle Area 51. Start small and build your operation from scratch. Unlock the secrets of alien biology, UFO construction, high-powered laser weaponry and interstellar travel and gain more funding from the shadowy government department overseeing everything. Maximize the efficiency of your facility by speeding up your processes; buy more vans, get more salvage, increase your research stations, train your workers and grow your operations! But you’ll need to work fast. Keep an eye out for the little green guys, get your tinfoil hats ready 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. You’re in charge of the facility so develop your strategy, reduce costs, increase revenue and know that the choices you make will decide the fate of your operation ...and maybe even the world!
