Hi people I need help to find an old horror anime I've watched so long ago, in the anime appear aliens trying to conquer planet earth, and one guy trying to stop them eventually finds God in a pyramid, also this guy has some kind of small crystal pyramids that give some sort of power. It's very bloody and violent anime

Crystal Triangle (87)
a.k.a. Forbidden Revelation: Crystal Triangle
a.k.a. Kindan no Inoku Shiroku Crystal Triangle

A daring globe trotting archeologist/treasure hunter is in a worldwide race against time, the KGB, the CIA, and the Yakuza to find a message that is said to be of divine origin. The message from God is the key to an ultimate power, and the one chance that Man may have to save Himself from annihilation by a rouge star.
The message leads the hunters to a ancient crashed spaceship.
