Combat in Second Life is one of the hardest types of role-play to achieve and represents more a life style than a role. Combat varies in many ways, beginning with simple Katana Fights just for pleasure and entertainment up to huge battles, envolving aircrafts, fleets and missiles. Most combat groups own their own combat sims, which are generally set to "Linden Damage" to exclude cheating with Combat Systems; means: you will die on these sims, if a bullet catches your way. Rules and their enforcement is a basic issue on any combat sim, and violating these rules will mostly lead to a ban.
