access to Weavers, who for various costs can boost certain effects on the player or traps placed in the manner of a technology tree; these effects only last for that level. Once the player initiates a wave, they can run about the level to participate in combat or place additional traps. The player must watch their health and mana used for their weapons but orcs may drop health and mana potions that will replenish these; alternatively the player can heal while in proximity of the Rift. If the player should lose all their health or fall off the level, they will respawn back at the Rift but this will cost them a number of Rift Points. After defeating the last wave, the player is awarded a number of skulls, up to 5 (or on Apprentice difficulty, limited to two), based on their score (reflecting how many Rift points remain) and the time needed to defeat all the waves. Skulls are used to buy improvements to traps and weapons in the player's spellbook, such as increasing damage, reducing cost, or making them more effective against the orcs. The player, after completing each level the first time, is also rewarded with a new trap type for their Spellbook they can use in subsequent levels. These improvements remain with the player, so that they may return to earlier levels with these improved traps to earn more skulls. Plot The story revolves around the Order, an elite faction of wizards and warriors who guard the Rifts, magical openings between the human world and the 'Dead World', which provide a source of magical power throughout both worlds. Using this power, the Order is able to maintain a perfect world for humanity by using magic to manipulate nature. In order to protect the human world, they have constructed magic-powered fortresses throughout the Dead World to guard the Rifts, particularly from the adversarial faction known as 'the Mob' - a brutish horde of creatures such as Orcs, Ogres and Gnolls which, despite being unintelligent, would otherwise pose a major threat to the human world due to their vast numbers. After a surprise attack by the Mob, the player character, known only as the Hero (voiced by Rob McCollum), finds himself as the last living member of the Order, as the Mob appears to have suddenly obtained a surge in both strength and intelligence.
