Quick not on fighting the Purge. They're pretty much perfect soldiers. I'm not quite ready to reveal how they're made, but Crusaders are effectively intelligent zombies with armour and swords. And occasionally flame throwers.

Also, the Singularity Bomb is bullshit. I'm having the Purge do an explody thing, but at least this explody thing is survivable. Someone could easily write a post about their power armour, mech suit or vamp powers allowing them to survive the fuel explosion. The singularity bomb would instantly kill everyone within a mile, ending the roleplay for everyone.

Also, the name is inaccurate >.>

A singularity is a point of infinite mass. As it has infinite mass, it's gravity is also infinite. The existence of any one true singularity would instantly accelerate every particle in the universe to light speed. Which would be bad.
