No No No! I will sum it up for you. Okay so survival 1-186 is stuff. and 219 is basically god gear. ok so mete did cool mods and yea and blah and im so tired i dunno what im typing anymore.
Okay then.... I'll basically type the basic stuff here.
Basically you get Tier 3 armor by completing "waves" of mobs in a new game mode called "survival" you have to kill a certain amount of monsters/viruses to get to the next Tier 1. In each Tier there's a possibility of the mobs dropping survival sets. The higher the Tier the better the armor. 1 being the lowest, 3 being the highest.
Also you mentioned bonuses if you wear the survival sets. You get 15% more EXP if you wear a full Tier 2 set and 40% more EXP if you wear a full Tier 3 set.
That's pretty much it.
