First, you’ll want some Armor – the higher the level, the better. Armor gives you the extra time needed to find cover and return fire. Also, pick up Armor plates. If you escape from a gunfight with broken Armor, you can repair it with Armor plates from your inventory.

Second, you’ll want a First Aid Kit or Med Kit to restore health after engagements. If you’re lucky, you'll find a Trauma Kit which gives max health no matter how hurt you are, plus a 50 health bonus for a total of 200.
