So I will only sum up this feedback in 2 words: "technical" and "difficulties".
I guess that makes the maps hard. I'm just not sure that's the kind of difficulty developpers were expecting to give us.
I'll expand quickly so that there will be no confusions:
The framerate in Ironclaw munitions factory is utterly LOW. I had done this map in the actual SK only twice, when they were first launched (this issue had already struck me). I died 4 times, I've got 34 days of playtime behind me, and to be honest, its certainly not skills I lacked. So I'll just repeat it once again:
a hard map usually is hard because of its layout, and its fighting rooms. Not because the framerate is twice lower than usual.
Second quick remark: the payout for these maps was of 2779 crowns. I won't waste time in maps that are bugged for such a ridiculous amount of crowns. I won't bother stepping in those maps anymore at their release. They are useless.
Now getting to FSC, that should be some real fun.
Oh yes, a quick message to developpers, or whoever's getting close to that: before thinking of releasing some ultimate super-death-nightmare hard content, wouldn't that be smart to make the game playable for all the players you're willing to host? Or you're just making your content aimed to the <50ms ping community with no care for the rest of the players?
the Ultimate Ironclaw was really hard (i resurrected about a million times) not much because of the traps or the enemies, but because it was such a lagfest, at least for me, that it was barely playable. (Granded, I managed to log in the test server 45 minutes before shutdown so we kinda rushed the whole thing, and also, my team's switcher sucked, but going from full health to zero during a lag spike is not a very pleasant experience).
I REALLY liked the fire addition, makes my targeted "everyay" suit of vog cub coat with divine veil the one that makes the most sense for this boss, and I liked very much the new twins' appearence. But PLEASE, do something about the lag, it's killing us (literally!)
