Set in the land of the Shapers (not connected to those in Nightwatch), Geneforge 5 puts you in the shoes of a lone traveler which can either join up with the Shapers and help them destroy the rebels or team up with the rebels themselves and fight against the Shapers. No matter what path you’ll choose, you’ll certainly have lots of things to do.
According to Spiderweb, Geneforge 5: Overthrow has a huge, open storyline. You can choose to serve one of five different factions, each of which has its own path to bring the war to an end. There are dozens of different endings and paths to victory: help the rebels or fight them, kill your opponents or use stealth and diplomacy, and much more. You can get a glimpse at everything by trying the demo offered via the game’s official website.
