Hate to be that guy,but...I've heard of Unholy, however, I still don't know what it is. Could someone quickly explain what this is all about, please?
Ever play Saxton Hale/Freak Fortress servers in TF2 or just boss minigames in any shooter?
Well, this mod is basically like that. Every round, one or more players is selected to be the "boss" and their goal is to eliminate the opposing survivors. In the case of the Unholy mod, every boss has a different bag of tricks up their sleeves, and they have set HP amounts that scale to balance with the number of enemies or allied bosses there are (unless one of said bosses is Sampi or Zankokuna Hellbot, who both just have 30,000 no matter what as they're the "superbosses" of the mod).
However, this one comes with a good number of other nice bits as well. There's a wide range of player classes to choose from and experiment with, and every player on the survivors' side spawns with certain kinds of item boxes that may prove helpful in a pinch. And to keep things fresh, every... 8 rounds, I believe? ... the mod will go into a minigame round where it picks one of several minigames just to mess about and have a little fun. They're quite nice and very hilarious as well.
There are a rare few bosses who only spawn under certain conditions such as the players having faced or killed a certain other boss a number of times, and there's one very special little bit - if only one survivor player remains and the bosses have killed everyone else during a round, that player will receive a random boost and possibly an item to give them a fighting chance (however, this may not always be good - sometimes the game will give you an item that basically just causes you to explode on use and literally tell you to give up, essentially giving you the option to take the "coward's way out"). If that player manages to finish off the remaining bosses, 1 count gets added to a special event counter that goes up to 10. When it reaches 10, the next boss round will spawn Sampi no matter what; he's barrels of fun to play as if the game happens to pick you for it but god help you if you're against him.
As such, there's a lot to see and do in this mod and in general it's just loads of chaos, nonsense, and fun. XD I highly recommend trying it out if you haven't already.
