You are the once-trusted bodyguard of the Empress. Framed for her murder and driven by revenge, you must become an infamous assassin, known only by the disturbing mask that has become your calling card. As you navigate a world torn apart by plague and oppressed by a government armed with strange new technologies, the truth behind your betrayal is as murky as the waters surrounding the city. The choices you make will determine the fate of the world, but no matter what happens your old life is gone forever.
Finally, Froger has done something with the Tautologist tool, here it is. It's not Ultimate Difficulty (as in it does not touch AI/Stealth/Leaning/Combat) but, I hope for it to give a more suitable feel of working towards a specialized build and not simply getting everything. Things I'm proud the most of are blink/double jump balance, to make them complete each other, not replace, and wind blast balance, to make it crowd control ability, not "use to win". More particular change log is in description. Also I've compiled many tweaks found in the internet: infinite bodies, HD shadows, more resourses for streaming etc.
All Piero's prices increased (now you have to collect ~80% valuables to buy all upgrades);
All Corvo abilities are re-balanced: now blink drains mana, wind blast doesn't kill bots, dark vision has limited radius etc.;
All first level abilities cost 0 runes, so you can get them right after the blink;
First level of "celerity" slightly reduces falling damage and increases swimming/ sprinting speed, the second one moderately reduces falling damage and gives you double jump;
Corvo's capacity is greatly decreased, as well as the capacity upgrades;
Bone Charms effects were mostly increased. Descriptions haven't been changed though.
