Welcome to Bricks in Motion

The year is 1972 and Area 51 has put multiple secret laboratories and facilities around the world. After a fatal in explosion in an underground base in Germany (That's right aliens finally landed somewhere else besides the US) though, one of the facilities is forced to shut down and it becomes closed of from all civilization. Many have set out to find it; see what remains, even though everyone that has gone in has never come out. This the beginning of a mini-series.
