You might not using all the mechanics. Try to hide behind covers, and spend points on perks which help you the weapon you are using the most. Tech ability gives you 5% more armor per level. Try to do NCPD things on the map, preferably moderate difficulty ones. When you finish a firefight, loot everything, than sell it. Don't buy weapons, rng will give you better ones eventually. Try out different weapon-types, gun, shotgun, smg/assault and sniper, when you find the weapon you are the most comfortable with, stick to those weapons.
Just what i was doing on very hard indeed.
Was wondering if you can sell multiple stuff like the drinks etc in one go?, since when i have to sell everything it cost like ten minuts
Like clicking Ctrl and hover over them one by on while left clicking, then sell the selection?
