1- Two Necro Warriors that work with Dark (Names will be revealed in the demo)
2- Yes, I will have a cool custom menu, I'm haveing trouble with one of the sub menus but, it's not so important.
3- No, I don't think Dark will be a secrect character you can get. Orignally in TBW2 Dark was supost to join the team but I lacked two things. A reason for Dark to want to join, and a reason for the group to accept him. However, there will be skirmish play [not in the demo]. Were you choose your team [<span style='color:red'>Humens</span>, <span style='color:purple'>Zombies</span> or <span style='color:green'>Animals</span>] and maybe even color. And in Skirmish play, you can be, Mark (Humens), Dark (Zombies) or Arbor (Animals).
I haven't started on the skirmish play and it probally wont be 100% for sure in the game.
