So, I had a friend over and we thought we'd play From the Abyss multiplayer for a bit. We both created new characters, since, after all, otherwise our levels would be vastly different; and we played through, with a few false starts, until we'd beaten the first boss. The game simply ignored it. We stepped into the teleporter back to down, and our kill against the first boss didn't count for either of us -- not only did we not get a reward, but none of the teleporters for the other levels we'd visited were activated. It is simply impossible to play through the game in multiplayer. This is, without question, the stupidest design decision in the entire game, and one of the stupidest (though sadly common) that I've seen in a multiplayer game to date. It make multiplayer essentially unplayable unless you happen to have a character of the same level as your friend by complete coincidence, and even then you can't actually get anywhere in multiplayer. Is there some way around this? Some cheat code that will make multiplayer actually, you know, work? A cheat that will enable every level, at least? Because as it is now, this is just stupid. Why include multiplayer if they're not even going to let you play through the game using it?
