The lobby/server joining is totally screwed up. If you try to "create a lobby" (the option to do this is hidden under the play with friends menu) it actually just sticks you in an existing lobby at the same chapter, but different level to the one you specified. so I have no idea how to actually create your own game/lobby. You can't select which level (only chapter) you want to play in survival mode, it just lets you choose chapter.
Can't see what's left after completing the chapters, only survival/vs mode.
Vs mode is fun (as the zombies, not as humans) apart from being hunter 15 times in a row, then boomer once.
Survival is OK, pretty nice idea, probably has the most replayability, but again, you can't choose exactly which level you are gonna play on.
Been votekicked from a few games on survival literally just as I join, which is annoying.
Has crashed to desktop several times.
Been checking the ocuk servers, and only ever seen 2 in use (constantly full for an hour or so, then emptied) so I don't know what times you guys play.
Not fantastic, but it's just OK really, not really my cup of tea, feels too much like a single player game.
