If you hurry, you can snag yourself a free game on Steam right now. The game in question is Hacknet, but it won't be free long. The deal ends July 14 at 10 AM PT (1 PM ET, 6 PM BT), when it goes back up to its regular price of $10 / £7. You can grab it here.

Hacknet is a well-received hacking simulator that kicks off when you receive a message from a recently deceased hacker named Bit who connects you with a hacking group called Entropy. That launches a series of missions in which you use the game's Linux-inspired interface to crack into secure digital spaces to access top-secret files and communications.
