Author: [Your Name] Date: April 18, 2026 Subject: Game Mechanics & Applied Mathematics 1. 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.
# Step 4: Bag & time bonus bag_bonus = 1.10 if all_bags else 1.0 time_bonus_mult = 1.0 + (0.25 * time_bonus) # time_bonus = 0..1 # Step 5: Infamy infamy_bonus = 1
