How to get ALOT of credits on Reach legitly and with no fear of being banned (I hope)

Ok. This method is not a cheat but more an exploit or a loophole in the game design.

1. Go to Campaign

2. Play ONI: Sword Base

3. Turn on all skulls except for Iron, Blackeye, and Tilt.

4. Make sure the difficulty is NOT Legendary, you will not survive.

5. When you start, go up the ramp on your right and kill the elite.

6. Go forward and instead of taking the ramp, drop down onto the ledge on the side of the cliff.

7. Run down that ledge until you reach the end.

8. Jump over he light, turn and run down the ledge until you get to the garage.

9. Go inside and equip the target locator.

10. With the locator equipped move as far back into the garage as possible until you get a checkpoint.

11. Fire a shot off at a group of enemies.

12. Press go to last checkpoint.

13. Repeat.

Note, killing all enemies will cause a checkpoint so leave a few alive.

You will get about 100 cr per cycle at first but that will decrease with time for some reason.

You can also get accommodations with this for extra points.

Enemies will NOT follow you into the structure save for the rare suicide grunt.

They will take the occasional shot if you get too close to the edge.
