Return of the Green Soul

From ZDoom Wiki

This will be the sequel to Realm of The Green Soul.

"The green soul returns in the second installment of the Green Soul trilogy. In 'Return' you descover that the Green Soul could never truly be destroyed by a mere mortal such as yourself. It's previous defeat brought no release from this world of madness and hate, and now you find yourself in a dense foggy wilderness... the lost fragments of a human dream gone horribly wrong..."

This new installment of the series will feature a full hub system with puzzles and new challenges along with a few new weapons and a new foe... 'Return' will also feature brand new music to add depth to the atmosphere, with an attempt at a more arcade action feel.
