I could finish the game much faster, but decided to map out most routes in the game (entrances to sewers etc.). Nonlinear and relatively large game area make it somewhat challenging to map. I didn't find the chainsaw + fuel and this remains to bother me. Projectile weapons are more or less the same so it's a good idea to get gattling and rocket launcher ASAP. I'm not sure about effects of most drugs, but hyper mobilat works as a stimpack. After using it once you have to take faery dust once a while to prevent brains from dissolving. Whole thing played without saves.
