Introduction Payday 2 (Overkill Software, 2013) is a cooperative first-person shooter centered around executing heists. Unlike traditional linear shooters, Payday 2 employs a complex, non-linear experience points (XP) system influenced by difficulty, heist length, stealth bonuses, infamy levels, and a unique “XP diminishing returns” mechanic for repeated heists.

Raw = 4000 × 3.0 × 1.8 = After heat = 21,600 × 0.25 = 5,400 Bags & time = 5,400 × 1.1 × 1.2 = 7,128 Infamy = 7,128 × 1.25 = 8,910 XP (final).
