Alright. I am obsessed with this game, so I thought I might tell you guys my strategy for killing any size horde on the first try. Before that, read the disclaimer at the bottom of the post. First, get either Napalm Molotovs, Molotovs, Pipe Bombs, or Frag Grenades, (All work, Napalm and Grenade recommended). You will also need the Chicago Chopper. Found in Crater Lake, Trust level 2, for about 3,500 Credits. If you do not get this weapon, this strategy will take a lot longer. Then, find the horde you wish to fight, throw your explosive choice 1,2, or 3 times into the main mass. Then, start to gain a lot of distance. Then, pull out your Chicago Chopper, and start shooting them as they come. Once they get close, activate Focus, and keep shooting. Once out of ammo, turn around and run. Repeat this process until the horde is dead. You may also throw a few explosives while running. I like to throw Pipe bombs at my feet, and let them run into it. DISCLAIMER! You will want to have a lot of stamina and focus, You dont need upgraded focus, but it will help. You will also want the Skill that allows you to reload while running.
