has been years since the first portal appeared on Earth in different parts of the world. Spewing forth multitude upon multitudes of monster on Earth. Not sparing a single continent from the invaders. A lot of solutions were brought forward. Several weapons were used, bombs were detonated, missiles were launched atomic bombs was used turning some part of the world into wastelands killing some of the monsters but the numbers killed were negligible. It was to no avail as those monsters were faster, stronger and a little bit smart. They feel danger and before they could get hit, they flee. After several setbacks and pointless sacrifices, humanity has learned it's lessons. In order to effectively combat this otherworldly threat, was to harness the power of the monsters and evolve themselves through defeating these monsters, absorbing their genome in their body, collecting blood orbs. Defeating the monsters this way, humanity grew more resilient and resistant than ever before. Humanity turned the tide from the brink of extinction to being at a stalemate with those beasts from he other side...Or not.
