CHIEF LEVEL UP
To level up your chief click on your avatar and on the "+" sign on your ep bar.
Leveling up your chief will also refill your stamina to full so you may want to get it empty by doing intel, rally or something else first.
Each level up will give you much needed talent points and rewards, so level up as soon as possible.
GETTING CHIEF EXP
The best way to get chief exp is to do your growth missions, be sure you complete them.
For talents focus all your points into economy, you should only use war talents when you need them for events or other activities.
Also make sure that you follow one path, the goal at first is to unlock the active talents and for that you want to go as far right as possible. You dont need to take both paths to unlock the next talent.
The research building allows you to incbuate biocaps to grow them, i recommend to use the 1 day scheme on maximum everyday for maximum growth.
Doing intel will give you hero fragments, be sure to level it up at the beginning. Every levelup will reset the intel.
You can activate various buffs in your HQ Building by spending biocaps.
If you are gathering you should nearly always use the 8h 50% boost for 100 biocaps.
