Beyond the core abilities tied with each faction, you'll have research options available. Each faction possesses three vectors of research divided into three tiers. As you work your way through the campaign or proceed in a multiplayer match, you'll open up a new level that you can assign to a vector. You can hold up to a maximum of six research levels. Whether you max out two tiers or spread them evenly between all three is up to you.

We’ll find out this fall if it reaches its lofty potential.
