Tutorial: Execute Ruthlessly
Your squad has learned the basics of tactics and survived the first challenges.
There will be worse to come -- so go forth and strike down the xenos with fire and steel!
Between levels, be sure to spend your Experience to increase your Templars' attributes.
As you complete each level or campaign, you will gain Templar Honor, which can be spent as a currency with the Fleet to requisition additional soldiers, armor and armaments. Be sure to upgrade your gear as you go. Within the tutorial, you are allowed to change your squad configuration and purchase war gear between every level. However, in a normal campaign this is not the case, so be sure to stock up properly before any long engagements.
