Awsome game! Easily a fun entainer after some time
At the start its quite hard cus you have very little ammo so its hard to kill the enemies. However after some time it get easier cus you get to kill loads of enemies thus getting you hundreds of thousands of money to get more stuff.
Save up at the start and get a dual pistols and a good amount of amunition(like 20-30). get atleast 5 gunmen and 1 crafter.
after that get more gunmens. 20 gunmens total should do well.
get 50 amunition. then buy a machine gun or the shotgun.(its better if you buy the shotgun, but you must be able to click very fast if not get the machinegun) when you get them simply keep firing at any enemy you see if your using the machine gun hold the firing. wall to max.
get atleast 50 gunmen and increase your ammunition to 100(or 300+ if your using machine gun).get more crafters if you are taking heavy damage (like you finish a day with about 50 damage).
also get a missile site if you can.
now increase ammunition to 150+ if you have shotgun or 1000+ if you have machine gun. get 200 gunmen. fortify to max.
save up.
get minigun and 1000gunmen.
blast everything
NEVER REPAIR.
