I've been playing this game for 2 hours now and have been thoroughly enjoying it, there were some parts that I found difficult such as the lock box code but was able to figure it out. I enjoy a challenge but im stuck in the factory, i've been searching for a while now, throwing myself at the big guy but have been unable to find the wrench! I've looked through playthroughs but the place where it is supposed to be only includes a letter!
