About Geneforge 1: Mutagen
Geneforge 1: Mutagen is a fantasy adventure set on a forbidden island, where you play as a Shaper: a wizard who can create life. You summon tools, traps and creatures, including powerful beasts that usually obey you. The island holds the lost secrets of your people, while invaders seek to steal and master them. You can race them to the island’s treasures, destroy them or join them.
The island and its factions
Explore more than 80 zones as you contend with rival factions and decide how to approach the coming rebellion, which will scorch your continent. You can choose between the factions or destroy everything. The story can lead to a range of endings, and you can defeat the final boss or switch sides and join him.
Choose your approach
You can fight with blades, missiles or magic, rely on your created creatures, or build an army of custom-made mutant monsters. Alternatively, use trickery, diplomacy and stealth to finish the game without attacking an enemy. Dozens of skills, abilities and pets support different ways to play, with more than 50 hours of gameplay and replayability across its different endings.
A remastered adventure
This remaster of the 2001 game adds areas, quests, characters and dialogue. It also reworks the interface and systems, along with every part of the game.
