...someone with an army made from 100M weapons and 90M alcohol attacks you, you lose it all and he will not even have a scratch on his big army.
Just the bazooka guys itself cost this guy over 1000$ if he bought them instantly with FUTURE tokens, mercenaries are another 600$, ninjas are 400$ and bouncers another 200$. This army is unbeatable for everyone still playing I would say! Or maybe even stronger army attacked him and he had to send the army away?
NextColony do have the same problem - there are no defensive buildings! There are shield generators, but they work the same as storages in DrugWars. They are useless because they will only keep safe your resources, but losing all of your unused explorers and transporters because you didn't have enough defense is much more costly.
The only way right now how you can still save your ships is to send them elsewhere when you see that someone is attacking you. It's possible in NextColony because the attacks do take many hours to complete but in DrugWars it's not even half an hour and your army that you were building for a week is gone - just like that.
