In other words, when you enter the Arise of the world u have to take the 7 time portals and in each time era find the 4 artifacts (SOMETIMES in a particular order, usually u can do them in any order you want), then go to the Blood's Tombe, get the ammo there, go to the Death Fortress and get the boss.

It's suggested that you go together, otherwise it will take long.

BTW in this topic I'll add some pictures to give you a taste of what the level is before I upload it tomorrow..
