guide is pretty straightforward. 

pay accordingly to the time bonus active. this will make all the difference in points. kill invaders ghosts and farm tiles when they double points. this is a good way to maximise the energie too.

key points in fury are 2x enemies and specially towers time. 

take advantage for the double kill and you can turn a defeat into a victory. 

for towers you should kill the easy ones and try defende the ones that the enemies will attack but struggle to burn them. 

always keep an eye on os settings. good opportunities usually appear in those moments and you may caught a good shield drop.

good luck and enjoy fury.
