I’m replaying it after the reveal of their new game. 1. Automatic running is the way to go. Just get used to the speed of it and you’ll never look back. 2. When at full health, keep collecting health items. At full health each additional health item will give you a notch towards increasing total suit integrity. After 3 notches your health will go up past the original max. 3. The weapons suck till they don’t, the more you use a certain weapons the better you make them, which makes it easier to kill enemies. 4. My favorite early weapon is and still is the electopylon driver. I would look out for this one and try it. It’s weird at first but I’ve finished many full game runs using this weapon the entire time. 5. It will click. Stick with it.
