Identify how many shots with each weapon it takes to kill an enemy. Different enemies will require a different amount of shots before taken down. Conserve and use your ammo wisely as there is not an abundance within the game.

When Paul is almost out of life, his health meter will turn red. At this time you can use 'The Voice' that will neutralize characters. Use you Krys to eliminate them and regain some health. You can also use the distiller to regain life if there is enough in the blue meter.

Always check what your objectives are in the menu. The objectives that are faded indicate that they have already been completed.

The game requires a lot of stealth movement. Use the mouse to peek around corners even when Paul isn't standing directly against a wall. You can almost 'cheat' to see what's around the corners.

Guards normally patrol or rotate, learn their pattern and strike them when they least expect it. Not giving them a chance to alert other guards will help increase your chance of survival.

Mission 1
Outside the harvester
Kill as many guards as you can using your Krys. The guards will turnaround while standing; therefore time it wisely to sneak up on them to take them out.

Mission 2
Killing Kynes will result in a game over. Be sure to let him live. You must find and deactivate the cannons prior to taking off with the Orni or you will be shot down.

Mission 3
Find the Green and Blue codes within the conveyor belt room. There are two magnetic passes that you need to find before continuing into the blue zone. To get past the laser beam that is stationary, lean against the wall and roll underneath it.
