Description
Baldur's Gate: Reloaded is a fan-made tribute and remake of the original Baldur's Gate using the Neverwinter Nights 2 engine.

The project started in November of 2006 and has slowly progressed since then towards completion. Our team size has varied throughout the course of development from as many as 5 members to as little as 1 member.

Both expansion packs to Neverwinter Nights 2, Mask of the Betrayer and Storm of Zehir, are required to play.
