Serpent: Resurrection

From ZDoom Wiki

This is the latest project by me (The Ultimate DooMer), a very ambitious one for Hexen. Using the very latest features and a fully scripted RPG system, this 25-map adventure will really bring the characters to life, as well as bringing all three Serpent Riders together for the first time in a proper RPG fantasy world!

Features:

7 weapons for each character instead of 4.
An RPG system, with experience, level breaks and customisable attributes.
A magic system with 10 spells and a variable ability to cast them.
New artifacts, puzzle items and keys.
A monetary system with buying and selling.
A ton of new monsters, graphics and sounds.
3 new music soundtracks - a built-in midi soundtrack plus two external mod soundtracks.

Progress:

Graphics and music done/compiled.
Items done.
Magic and RPG done.
Weapons and monsters done. (a redesign of bosses is planned though)
Maps are all fully-designed, the first 22 are in varying states of construction.
