Ok, the demo version is ONLINE.
http://www.trproductions.net/parasitequarantine/media/parasiteqdemo2.rar
It's a 150mb RAR file, so you'll need winrar to open it.
The demo contains 4 levels, which levels 4-7 of the final game.
So, turn off the lights, put your headsets on, amp up the volume and enjoy!
Here's a few tips on the gameplay:
-Read the computer screen messages. When you walk near a computer a (storytrigger) message appears. These messages contain valuable information about extra ammo, key locations, alternate routes etc.
-This is more a sneak'em up than a shoot'em up. Conserve your ammo and be constantly on guard.
-Most of the levels contain several routes to levelend, so search around. Some routes are easier than others, some require different skills than others.
And most of all:
Be afraid, be very afraid.
We've seen the world burn! We've seen the sun eclipse from the smoke of the burning dead!
