Invest in some good personal protection ammo. There will be a lot of debate about what's best, so I'll start it off with what I use. Extreme Shock bullets that are made of basically powdered tungsten. I love their line... The compressed Tungsten-NyTrilium™ Composite fragments upon impact, leaving a wound channel of catastrophic proportions. It also rarely penetrates interior walls, so you don't have to be as worried about ricochets or bullets missing and punching through to other rooms. It's what I like. I'm sure there will be lots more opinions!
