Tips:

Combat Boost:

When you are transported to the alien world, find the round puddles and stand in them. In many encounters, you can save your butt by standing in them and fighting. They supply infinite health and when you are injured they will slowly raise your health, therefore, you will not take as much damage. (Note there is one encounter that will almost require you to do this unless you are an exelent player and/or you have full suit health)

Turn off the Flashlight:

To turn off the flashlight, pause the game and hit your flashlight key
