Primary Melee- Machete (preferrably a military issue but since that'd be hard to obtain, a standard Sports Goods store version)
primary ranged- MP5/N (small, light, accurate, not hard to get your hands on and uses the most common type of ammunition)
secondary melee- ball-point hammer (for breaking locks / windows / zombie skulls)
Secondary ranged- Sig p226/228 (accurate, reliable, easy to obtain, and no matter what variant you find it'll be chambered for an easy-to-find cartridge)
Primary- XM8 Sniper configuration, or if i could swing it a Barret M82A1, but that is just my dream weapon
Secondary- 2 Jericho 941 semi auto pistols, to be fired one at a time of course and a .45 Raging bull
Melee- Probably no short of 5 knives.. at least 2 of them being 6' and the others a bit shorter
Secondary Melee- Short Katana
