Ingress - destroy shield

Save Ultra Strikes for those important attacks, and to destroy Shield Mods.

Most of the time, you will use XMP Bursters to attack. Since this is the most common weapon, use it for general attack and capturing portals. Ultra Strikes are harder to come by, so save those for when you want to attack hard. It has a smaller blast range compared to XMP Bursters, but they do more damage. If you stand directly at the center of a portal, you can destroy Shield Mods with a few Ultra Strikes. So save them for those important attacks.
