So the mode is actually great, and i am wondering who has had a chance to play it yet? I have maxed 2 characters it is very addicting. The raids are very difficult but extremely rewarding once you get good enough to do them. The leveling system is similar to Destiny but no where near as grindy. I would suggest playing the original game on at least hard though before going online as it can be tough at times
There is like a story mode which has several missions, and then you have survival which currently has 3 maps (all of which have 3 levels of difficulty dependant on your level). There are also the 3 raids which are huge and can go on for hours which you need co-ordinations and mics are a must. There are the 4 classes hunter, samurai, ronin and assasin. All are very unique and fit different plays styles. I started with assassin then moved to samurai. Currently leveling up my hunter though
My impressions for a FREE online add on have to be 9.5/10. They also updated it very quickly with quality of life improvements across it after feedback from the community. They really care about the game which is great to see. Id love it if it got a PS5 upgrade eventually. I would say it is probably in my top 3 favourite single player games ever, and the online just sweetens the deal
