The mod expands the content of GF5 without altering existing quests\endings\content by adding a new, large, quest chain for Shapers \ Lifecrafters (only for those). It adds choices, it doesn't remove any existing ones. The content is combat-light... unless you decide otherwise.
The only assumption this mod makes aside of the game is...the identity of the amnesiac protagonist, that he discovers bit by bit.
As such the quest chain can be completely ignored without any effect on GF5 game. Or... you can follow it, discover clues of who you are, choose to ignore or believe them, set up a research laboratory like so many NPCs have, discover amazing (but not game-breaking) powers and perhaps settle some old scores with past enemies.
To be clear, the protagonist doesn't discover any concrete proof to confirm the theory on his identity. You even have the choice to reject the conclusion at the end of the identity quest as false. But if you do, you won't get the idea to build up the laboratory.
I believe the mod increases the replay-value of GF5, since not only it adds exiting features and quests in certain locations, but you'll keep an eye open for the now much-coveted research notes in areas not affected by the mod.
At the end of the quest chain you manage to do something most people considered impossible. Both people in the game and gamers that play the game alike.
You can find the mod (V1.1) here:
EDIT: I'm working on a new mod for Warriors and Guardians. You take command of a Rebel outpost. See post 19 for more details.
About my motives: Why I decided to spend that much time on a mod.
