Hello there.
I dled SK yesterday, tried it a bit. The game looked nice, concept was fun, and the game seemed pve mission based.
However, i'm wondering if there's any challenging missions/dungeons or something like that? Somethin that is hard because of mechanics not due to insane gear requirments.
Well, T2 and T3 are significantly more difficult. Better gear does make it easier, but not a whole lot. You have to use skills you learned from the previous tiers to not die horribly. First there're danger missions that unlock after 4-1, which are pretty much what they sound like. Then there's the Firestorm Citadel, the premier dungeon in T3 and which first-timers tend to find quite difficult. And finally there are Shadow Lairs, which are souped-up versions of the boss dungeons, but have an exorbitant entrance fee. Every enemy becomes a whole lot tougher mechanics-wise later in the game. There's also the wilderness of the clockworks, which have a whole bunch of random levels that vary in difficulty.
