I got inspired from the following thread about bad zombies in MP. http://theindiestone.com/forums/index.php/topic/6687-has-anyone-really-died-from-zombies/ Right now the zombies do grab (althou it doesn't work 100% in MP) which is a good enhancements from the previous state. But I'm thinking maybe zombies could also be able to intersect the player from his/her running speed and direction. Best explained in pictures. This is the current AI: But I'm thinking that zombies could also be able to do closer to this: Now of course not all zombies should be able to do this, and no zombie should be able to do it to 100% perfection. Maybe there should be an Effectiveness Parameter which determines how good a zombie manage to do this and this parameter could maybe be constantly randomized to give some variaty. I did a quick search and this has somewhat been touched in the following thread but I thought it to be enough different for it's own thread. http://theindiestone.com/forums/index.php/topic/7052-zombie-variety/ EDIT: I ment this as a tool to give the devs the ability to SLIGHTLY increase the difficulty with the change of a few parameters. I did not mean that the game should change from HARD to IMPOSSIBLE.
