There aren't many cases where it would result in death. The bot would know there's no path from the ledge into the pit, and so it wouldn't overwalk it in most cases. However, it could jump and overshoot when people park vehicles right on top of nodes. The vehicle will prevent the bot from reaching the node's radius and so the bot will be trying to climb the vehicle and get to the node until it respawns or moves. You can't assume that it's safe to increase the radius in which it considers itself at a node in such cases. For example, if the bot needed to traverse some thin structures over a pit then it needs to follow paths very closely. There are some solutions, but it's best saved for version 2 when this is done. Don't expect the bot to play perfectly. It's not gonna stand up in a server full of regular players, but it will be fun to watch. If it can win against my non-gaming friends, then I'll be happy. I think it would be cool to just set it up on my laptop driving a hog around while I gun in the back (can't expect better from drivers in halo anyway ;p).
