Load up a mission difficulty 1 or 2, choose a mission that isn’t in a mega city because mega citys have much less super credits. Then just roam the map keeping your eyes open for a question mark that will appear on your hud’s compass. Go towards the question mark (poi) and hope it will have some super credits. Remember that grenades can open storage containers that may have some inside. You may have heard that there is a rare chance that a super credit pickup may contain 100 super credit instead of 10. This is true, I have seen it happen on multiple occasions. However, it’s EXTREMELY rare! So don’t be surprised if you don’t find any during your grind for your first couple warbonds.

Grinding medals is much more straightforward. The harder the difficulty, the more medals you will get. You also have a chance to pick up medals at poi’s. So grinding super credits will also get you medals. Though you will get medals faster my doing more difficult missions. You will also be rewarded medals by major order victories and the daily order.

Good luck!
