Project Art Thief
Project Art Thief (working title) is a cozy non-violent stealth game. You'll get to wander around beautiful museums and galleries in a european city, map their weak spots, and sneak in and out unseen to replace pieces of art.
"Replace"? Yes. You see, you've discovered that your late grandma was an art forger! In an effort to save your family name, you decide to swap back the real works she stole with the forgeries she left hanging in the museums.
