Veteran MMO players will remember the infamous trains from classic MMO EverQuest. A "train" happens when a player flees danger in a dungeon, and the enemies chasing the player come in sight of other unsuspecting players who are then attacked. This problem is fairly minimal at present in Project: Gorgon because the enemies don't pursue very far, but be aware that the mechanics allow for it. Don't be angry at other players! It is simply the mechanics of the game, and it could be argued it makes things a little more... interesting. As there is no experience penalty and also no loss of levels in the game (so far), a train will at worst cause your character to respawn in the entrance of the dungeon.
