The guild is a core element of Guild Wars. Though a player is not required to join a guild but often it’s a good way to get help from more experienced players as the in-game guild interface allows communication between guild members. The guild is distinguished from others with cape. What is cape?
Heroes are like “bots” and they are assisting you with the mission or whatever you’re doing. They are customizable (player can select skills, weapons, armour…). Player can do lots of things with heroes – control skills, flag them (set waypoint)… Heroes are unlocked through the play and can be taken into both PvE and PvP areas. More? Click me
There are three campaigns of the Guild Wars game. The first one is called Guild Wars Prophecis and it’s a stand-alone game. The second campaign’s called Guild Wars Factions and it can be played as a stand-alone game too (Thanks Martin! ). The third campaign is Guild Wars Nightfall. This campaign is a stand-alone game and it’s very popular among the players. The newest edition of the Guild Wars is called Guild Wars Eye Of The North. It’s interesting how I found this game. If you look when the first 2 campaigns were released you get my birthday date.
