These are just some tips for conserving ammo and such.
- Aim for the gut. Its actually hurts the enemy more that a headshot. I know, Its weird.
-With the hacks ( those floating red machines that spin with blades ) dont waste your ammo. Crowbar them bitches!
-The shotgun is overly effective in all situations. Use it. Also the right trigger allows you to fire 2 rounds at once. BIZNATCH!

Thats all I got. Add your own!
