Before there was Dead Space, There was System Shock. You take the role of a Cybernetically enhanced soldier onboard the Vaun Braun where it has been hijacked by worm like Parasites infecting the crew members. The game is similar to Doom 3 in its mechanics, but more fast paced and freaky. The story line is twisting and turning with suprises around every corner, and the audio logs around the ship allow for this mysterious outbreak to be solved. From signing up into the UNN, to killing every parasite, System Shock has it all. Weapons of every kind can be acquired, as well as Psi powers and upgrades. Enemies range for cyber gored Women to freaky hybrids with pipes and shotguns. Best of all, there are no cutscenes to slow down the game; all audio logs and Voice transmissions from the doctor who helps you are all kept in a log to check back to at any time. With so much information, it is hard not to get lost.

Made in 1999, still being played in 2012.
