Great comment, Chilese. I completely agree that a great feature of this game is that it can be played and enjoyed so many different ways. I didn't know about the tip of sending the city right to a collector. Makes perfect sense now you said it. I don't like micro-management, say I'm too lazy for it and I play the game leisurely.
1/6 12:09 with the same strategy, and still far from being perfect. the trick is to coordinate the launch of a drone with the movement of some blasters to take over the big plateau on the right. advancing on the ledge would be way too slow. another strategy (not tried but may be more efficient) is to take over the hole at the center.
1/7 7:09 plain vanilla strategy move up then left then put a mortar next to the hole top left then invade the mountain on the left with the help of a drone to speed things up.
1/6 13:03 particularly simple strategy, move the base to the left, build lots of energy + one mortar then conquer the part on the left with 4 blasters then conquer the plateau on the right with 3 of the 4 blasters + 1 drone.
Do you realize some people here on earth don't have a twitter or facebook account? i don't think they should be penalized for that and not be able to get as many stars as others. only 4/5 because of that, great game otherwise.
Thanks dvShrike, this works. The drone has to be well hidden in the corner indeed. I am not sure two blasters are needed for this to work, I still did it with two as you suggested and ended in 18 min. I guess the level is beatable in 15 or less. I didn't care for the upgrades though as I think they're a waste of energy.
