Die by the Sword is a swordfighting action-adventure video game developed by Treyarch and published by Tantrum Entertainment (a sub-brand of Interplay Productions) on March 27, 1998. The game allows players to independently command the movement and swordfighting of their in-game avatars; running, jumping and turning with one hand, while simultaneously slashing, stabbing and parrying with the other. Die by the Sword also offered deathmatch and cooperative multiplayer play in its arena mode, where players could stage fights with up to three other players. The expansion pack Limb from Limb was released on December 31, 1998, and added another main quest for the single-player campaign, enhanced multiplayer through a selection of significantly more creative arenas, and introduced new playable characters such as the Minotaur. A spiritual successor to Die by the Sword was released in 2000 exclusively for the Dreamcast, entitled Draconus: Cult of the Wyrm. Gameplay The game allows the player to fully control their sword arm, removing the need for pre-recorded animations and statistically based gameplay. Instead, a physically correct model is used for each avatar and each weapon, and both movement and damage are calculated through forces. The sword arm can be controlled by using a joystick, the numeric keypad, or a mouse. For example, with the keyboard, to perform a slashing attack with the default key combination, a player would press the '4' and '6' keys on the numeric keypad in succession. This will move the weapon from extreme left to right. The '8'-'2' combination will likewise perform a top-down striking motion. Blocking is accomplished similarly, not through a separate key or state like in all other games of this genre, but instead through the simple physical principle of positioning the weapon so that it intercepts, and blocks, the enemy's weapon. Shields operate like swords in this respect, though it is generally not possible to directly control the off-hand. Alternatively, a player may opt to directly control his sword arm with mouse movements or a joystick to gain more subtle control. This allows a player to fluidly move his weapon in any direction instead of being limited to the eight points of a keypad. However characters featuring a weapon for either arm can only be properly controlled by keypad or by using predefined moves, due to their unorthodox movements. A third and simpler method to using the mouse or keypad (as the mouse control can be
