The game has loads of bugs to the degree it often becomes flat out unplayable, but it's also just not good in general. For one, the maps are needlessly large and empty which causes a lot of uneventful running from one point to the other. The game also has incoherent objectives which often leave you confused as to what you're even expected to do and the tiered disguises system is awful in terms of just how one disguise is the most dominant even though enemy ai STILL sees through it somehow.
