Boat 6 = Black Hammer?
Finished it when it first came out. Some of the battles are fun, the new enemies are kinda neat, the bosses are fairly interesting (mainly Black Hammer).
Unfortunately it uses the same old formula of "4 stages of random nonthreatening trash mobs to speedrun through, final stage = boss" on almost everything, aside from the dungeons where perhaps an easy miniboss or two are thrown into the mix.
Also the Black Hammer cutscene is the worst thing ever, and if you don't hit Esc to skip it, everyone will hate you.
Err... if you're playing the missions that can be solo'd on hard on normal mode with 3 other people it's nobody's fault but your own that it's boring. The enemies are pretty threatening in fomor base, they're determined to hit you and most of them can kill me in 4-5 hits once my mana shield is out. Still, I've managed to solo most of the missions on hard including the one with vehemence in it.
And yeah most (not all though) of the areas in the base copy pasted, which is annoying but there's a bunch of new level styles right after fomorian base so I don't really mind. That and it's part of the story line - the fomorian base is inside the prarie (which is what it looks like).
