This is the game, where, considering your high skill, you can easily kill tons of brutal thugs with shotguns, tommy guns and other serious stuff, but you might be killed by the only one rat on the level simply by standing on it and having low hp.
1hp_per_second/10 . Would stand on the rat again.
P.S. To be serious, this is truly a good game. If you have the chance to buy it - don't avoid it, it's totally worth its money. Great atmosphere, appropriate-criminal music, good voice acting, and, of course zippy swearing (oh, and by the way, all the gore-lovers would enjoy the dismemberment).
Unfortunately, this game doesn't support the steam overlay. Speaking about resolution issues, here is a guide, describing how to run the game with the 1920x1080 resolution without cracking any .exe files http://steamcommunity.com/sharedfiles/filedetails/?id=170642945
