Resident Evil Revelations has a great horror-filled story in the Campaign mode with all kinds of puzzles to solve, but it also has a large number of collectibles such as the Tower Emblems.
Tower Emblems are hidden about the episodes, and can be destroyed with a bullet or well-aimed knife slash. They're pretty hard to find but they do unlock some pretty cool stuff for the game so it's well worth the effort to sniff them out.
They're hidden so well in fact I didn't even notice a single one on my first playthrough...
