The game can be summarized with the following:
Epigenesis is a love letter to Quake and Unreal Tournament’s Bombing Run. It is a mix of the games that we at DS3P miss from the time when we grew up, and we want to give that same experience but with a modern twist to today’s gamers. No matter if you are one of the old Quake players who miss the twitchy shooter, or if you think you know the meaning of the word “hectic”, Epigenesis has something for you.
