The Temple of Elemental Evil is a faithful adaptation of the Dungeon and Dragons roleplaying game module of the same name, using the D&D 3.5 rules.
The player leads a party of 5 adventurers exploring the mysteries behind the old temple of elemental evil. The player's objectives and the game storyline are different depending on what alignment the player has chosen for his party.
The game features an overland map for travel between locations with random encounters, location maps to explore in real time, and turn-based combat with a rather faithful implementation of the D&D 3.5 rules.
Some game features include enchantment (creating magic items, potions and scrolls), henchmen (hired characters who receive a portion of the loot as payment), standard 3.5 edition races and classes (capped at 10th level, though user-created add-ons allow to go up to 20th level), dozens of different monsters and a faithful recreation of the original module, including NPCs, encounters and maps.
