Here is a snippet:
"You can also explore the entirety of South Park, with nearly every building and house able to explore at some point or another. Through environmental puzzles you can work your way through the secret-ridden areas as well, collecting loot to equip and junk to sell to vendors. Besides levelling up and the various stat increases this provides, players can attach modifiers to their weapons and armour, buy better gear, learn new skills and more to keep up with the onslaught of the ridiculous army that's thrown at your party.
