Felt the same way about it. The plot device of the character potentially becoming Keanu really broke all motivation for me. Why would I complete the main plot if each mission made the infestation worse? I made this character, why would I be interested in watching them become someone else’s Gary Stue? I wanted to be my Gary, not theirs.
The story would have been much improved by dropping Johnny Mnemonic Silverhands and instead having the partner, whose name escapes me because I only got to know him through 2 missions and a 30 second montage of us getting to know each other, as the ride along personality. Instead of him taking you over, he’s fading away and you have to save him.
Throw in a heroic sacrifice from your semi AI partner at the end or a plot twist him into a villain Tyler Durdening your ass while you sleep and it could have been something magical.
