10 Disgusting Video Game Achievements You Should Be Ashamed Of
4. R. Kelly's Protege - Postal 2
Achievements don't get much more vile than this. You've been warned.
The highly politically incorrect Postal 2 is entirely consumed with being as tasteless and irresponsible as possible, and to that end included an achievement named "R. Kelly's Protege," which is unlocked when players urinate on an NPC until they're sick.
If you know much about R. Kelly at all you're probably aware why the achievement received his namesake, and as such it's one of the most stomach-churning goals you can actively seek out.
That said, considering how thoroughly the game encourages you to urinate on everyone and everything in sight, you're quite likely to end up popping it sooner or later regardless.
