Credit Farming Made Extremely Easy
While there are many ways to earn Credits, or Credits, in Halo: Reach, this is the easiest strategy we've discovered so far. Choose the Mission Start ONI: Sword Base and turn on the "Free For All" option under scoring options. You can set any Skulls you want but you probably want your difficulty to be Normal -- it's hard to do this on Legendary. Basically, you want to skip the first fight entirely. Run up the ramp to the west and jump onto the little wall to the north that wraps around to the road leading south. Sprint to the gate and grab the Target Locator from the suitcase along the western wall. Next, you'll want to set a Checkpoint -- this matters quite a bit, so don't ignore this step. Move to the south end of the gate and aim your locator north as the enemies approach. As you tool around by the closed southern door, you should get a Checkpoint. Now, aim the Target Locator at the street to the north and pull the trigger. Try to catch as many enemies as possible in your blast. This will earn you Credits -- probably about 100, based on your Commendations and Medals from the blast. Now, revert to the last Checkpoint and repeat the Target Locator blast infinitely. You get Credits for earning Medals Commendations, so the exact amount will vary for each blast depending on your Commendation progress. You should be able to work towards Commendations like Leadership Element and Splash Damage, while also gaining a set number of Credits for the Medals you win in each Target Locator strike. Using this method you can safely rack up Credits at the rate of several thousand each few minutes!
