Manhunt is a competent action/stealth game hybrid and manages to be surprisingly tense at times. In retrospect, the public outcry this game endured back in the day is a bit ridiculous considering the comparatively low graphical fidelity. Nevertheless, murdering someone with a plastic bag is still kind of gruesome and piling up corpses in a dark corner never gets old. Fun for the whole family.
A word of advice, the enemy AI breaks at high framerates so it's crucial to lock the fps at 60 from your graphics card panel. Also, consider paying a visit to the PCGamingWiki just in case because the game is prone to crashing.
