Hide and Shriek is a 1v1 game about two students at opposing schools being invisible and having a game afterhours. The game play with scoring by either tricking your opponents with traps (via rigging them along the ground, doors, cabinets, etc) and by finding your invisible opponent and shrieking them, 3 shrieks in a row and you win automatically!

Each match lasts 10 minutes and all 10 of those can be filled with tense searching and hoping that your next touch isn't going to throw you across the room by a gust of wind, or that cabinet you touched might electrify you, or even that noise you heard is your invisible rival opening something right next to you unknowingly.

It's a fun little game, an added bonus if you're a fan of The Secret World in which this game has goodies for, the only downside is possibly the lower population of players further down the road after halloween.

Edit: As of late November I've found the game a bit more difficult to find players with. So having a friend to play with you would likely be the best idea!
