This is not a normal game with multiple levels in the one game but is released one episode/level at a time.

Instructions

Collect survival items

The aim is to make it through while finding the 3 essential survival items top left.
They are, power, nutrient and antiviral (left to right).
You can progress to the next areas once you have collected these items.

Health bar

Your health is displayed top right and changes from green to amber to red with each hit from the creatures.
If you health drops below red, you contract the virus which turned these creatures mad, and it's game over.
The antiviral you collect are for several other viruses you are protected from.

Interaction

Objects you collect appear in the bottom right corner.
If you move nearer the camera, if 'turn camera' appears, you can press enter to turn the camera for a look the other side of the room.
A white arrow indicates which way you will go.

Plasmagun

You can fire this weapon using the Ctrl key. Approach the creatures and the cyborg will scan and target lock on them. A white target appears over the creature to confirm lock. There is a small delay as the plasmagun charges. It's an old alien weapon picked up by and attached to himself a while ago.

In the bottom left are the icons for Life forms scanned and Plasma shots left (left to right).
