"Epilogue" is the last mission in Act I, The Locksmith's Story. This level is a multiplayer level that introduces Player-versus-Player (PvP) mechanics. As such, players must compete to get the five trophies and exit the level.
The epilogue is meant for multiplayer parties only. Take what is yours and escape alone! READY?
Unlike cooperative levels, players must steal all four trophies on the level and escape on the rescue vehicle alone. Killing/incapacitating other players will cause them to spawn a self-reviving corpse and drop their trophies.
The Locksmith: "They're still out there, y'know."
The Locksmith: "They'll offer penance to whatever god they believe in... "
The Locksmith: "...And then they'll sin again. "
The Locksmith: "A scorpion can't escape his nature. "
The Locksmith: "And rats will eat their own..."
- "Rats Will Eat Their Own" by Austin Wintory will play once a thief has all four trophies.
