What are the different types of Resources?

In Operation New Earth, there are several different types of resources that you will find and use on a regular basis.  Many of them can be gathered in a variety of ways.  Tech, Food, Oil, Alloy, and Neutronium can all be granted as a Mission reward, collected from crashed Alien Ships, gathered from resource deposits on the World Map, and won in the Gambling Den.  In addition, all resources (except for Alliance Credits) can be purchased using Shards.

Alliance Credits
Alliance Credits can be earned by completing Alliance Missions and by assisting other members of your alliance by tapping on the "Assist" icon that may occasionally appear in the lower right corner of the screen.  If you leave an alliance, you will not lose any Alliance Credits that you have earned. However, you will not be able to spend them until you join another Alliance.
