Where Roleplay and Tactics Collide! Massive, beautiful world; original areas; and overhead map. Roleplay required and rewarded. Tactical group PvP. Player-run cabals with raid system. Advanced economics. Newbie-friendly mentor system. Hundreds of quests. Free to play! Shattered Kingdoms is a roleplay-enforced MUD that successfully unites quality roleplay with the tactical considerations of challenging PK.

While killing other players is restricted only by roleplaying requirements, it is possible to play a non-violent character as well; experience can be gained through quests, roleplay rewards, bonuses for discovering new areas, and casting spells.
The description of Shattered Kingdoms on several sites leaves no doubt (at least in my mind) that tactics refers to PK.
