Zombie fighting is serious business, and requires specialized tools. However, due to the wide range of zombie types, available weaponry, and combat preferences, the equipment chosen for the task is often variable and strongly debated. What would YOU use? What would you reccommend for different situations? Factoring in cost and availability can be important... as nice as it would be to be in fortress stronghold with a battalion of rocket-launcher-wielding commandos, it's not particularly realistic.
So. Flamethrowers, rockets, Molotovs, grenades, pistols, snipers, chainsaws, vorpal sporks... what's your choice?
