i think it wound be good to have a button to harvest the compact houses and the mines at the same time so you wont have to be clicking on each of them.
i find it funny how in the tutorial it says " the minions will do all in their power to give you success". and later on in the game if they get cought by police they surrender immediately lol. even if your minions have good weapons.
i don't really think they need a new gun, but just a little more regeneration and a lil bit more life could do it so i can stop dying at 100K+ points.. =/
