Before Dragonwolf Interactive was a thing, I did create a couple of games/mods during my years studying.
Weatherman is a fun little Mod for Doom 3 that allowed the player to change the weather around him.
Color Sucker on the other hand lets the player indirectly manipulate a balls projectory to solve puzzles.
Also, I did make two big modifications for Doom 3 while the biggest one took around five years to complete.
Hell Island was my first big release and while it wasn't very pretty, it had a fun gameplay that people liked.
Desolated: The Crying Fate was my second mod to be released and it is a huge story driven shooter-adventure with many different environments, game-modes, difficulties, secrets etc.
