Not sure if this is a known issue, but I was able to unlock Lina's first corruption level without following all the steps in the in-game guide. The guide calls for Nerve 4 and pursuing a certain scene with Alex. I instead had Nerve 2 and caught Lina watching Sami after our horror movie foot play. Lina and I enjoyed our time together (I made sure to aim properly), we went our separate ways, and I got the unlock.
Is this by design and the guide is simply out of date? Or did I stumble into something that was never supposed to be possible?
Loving the game, by the way. Excellent writing. Looking forward to more.
