This is a good scenario as long as you don't play with the persians, which is the default. The object is to kill player 4 and to bring the artifact, hidden somewhere on the map, into player 4's base. You cannot build a temple or a siege workshop to accomplish this task. The problem with the persians is that they have no Academy and without the Academy, you cannot achieve the Iron Age. Player 4 is guarded by some ballista towers which have no problems wiping out any of the bronze age units you can build. Player 4 also has a lot of priests so a chariot civ would be helpful too. Players 2 and 3 are also enemies but are weaker than you so you can either ignore them or destroy them. Should be a pretty fun and challenging game because of the lack of cats. Nice job.
