My guess is Dead Stop would be a mobile phone game, where you have to kill zombies trying to break into your safehouse. And it would be awful.
But when they get round to a sequel like i have said before they need to have either seperate single person campaign or team campaigns. Because i don't like playing these games online having to talk things through with someone i don't know, and i get really put out in the cutscenes when all four of the characters are in the cutscene after i have done everything on my own, or when people refer to me as a group of four people in passing. just a niggle that wound me up.
Also as decent as the melee combat was, i still think it needed work, it was too hard to time you attacks with a longer weapon to hit the enemy on approach, and then he would start swinging like a muppet when i have a hoard around, odd things happened in combat every now and then.
But it was a good game and i would love to see a sequel.
