Step 1: Make character with HtH or Melee or SG tagged, rest of the stuff is optional and your choice.
Step 2: Spawn, and instantly start looking for a source of junk, gather large amounts of junk by stopping on city tiles without encountering monsters.
Step 3: Make junk in to BB's, and sell for stupidly large amounts of caps, or barter for anything else you want, but mainly you want a weapon to kill brahmin, plus ammo.
Step 4: Go up to modoc and pwn zeh moomooz, and dodge moonshiners, unless you have an SMG and 10 AG (Read your specials) and are at least level 6.
Step 5: Make tent, gather more junk, make more BB's, sell for more random stuff you want or caps, and do it over and over until you finally get bored and want to shoot something again.
And poof, if all things go well you will be well armed and have a tent, money, and guns in under 1-2 hours, at least if you have a decent ping (150-200) and can hunt in real time.
All without being a jerk and base raping people, since that's the other "Get rich quick" tactic.
