It's just as funny as Portal but for all the wrong reasons.
So what kept me going anyway? Like Portal, it was the hilarious dialogue, but unlike Portal the humor is completely unintentional. See, there are bad dubs and then there are hilariously bad dubs. If you were to play Twin Sector with its original German dialogue, the game wouldn't have a single redeeming quality, but turn on the English dub and you'll be LOLing through to the very end as you cheat past the puzzles and enjoy the next exchange between Ashley and OSCAR, who I will argue to the death is just as funny as Portal's GLaDOS - but once again, for all the wrong reasons.
And yes, make no mistake about it, this is Portal done wrong. Very, very wrong. I think I'm being generous by giving this a game a 2.0, and that's only because Ashley is so damn pretty to look at.
