Histacom is a hacking game set in an ultra realistic computer operating system environment indistinguishable from the real thing. It has the unique feature of time travel never before seen in the hacking game genre. The time travel aspect adds great depth into the game allowing the environment (operating system) to evolve as you leap through different ages in computer history. When you start a new game you are thrown into 1998 using Windows 95. From there do a little exploring on internet explorer or of the operating system. Finally perform a Google search to access a secret webpage which will get the game in motion. (clue, 12padams copyright logo). Steal the alpha version of the secret time travel software and get ready for a crazy ride. The game currently has 5 different years programmed into it with 5 different operating systems. The game is mostly linear but does eventually split into multiple paths when you make decide how to fix the future by traveling to the past.
Yep, you can seriously mess the course of history up while playing this game. That's the fun of time travel. Not only do you get to see different operating systems through history but you also get to see how all actions have a reaction :)
