Wanna see a crazy experiment in game design? Experiment 12 is a collaborative game created by twelve developers, with each level building on the story set by the previous ones. You wake up in a testing chamber, but it's hard to tell where you'll be headed from there, as each level chapter introduces a new puzzle or platform element for you to tackle.
Kairo is a first person puzzle adventure game from Richard Perrin, creator of The White Chamber. Set in a minimalist, somewhat abstract world of temples and stones, floating pathways and mysterious mechanisms, you'll be given no clues as to what you need to do to complete the game. Instead, you'll wander through room after room, using your keen powers of observation to figure out where the puzzles are and how to solve them. It's a game design choice rarely seen since the days of Myst, and it brings with it a satisfying gaming experience that has become increasingly rare in the age of tutorials and online cheat codes.
