meh wtf
I spent about an hour on the factory campaign, but only to get stuck on the last few rooms because it was impossible to beat those rooms with my setting. I had 3 lvl 9-11 autoguns and 3 lvl 9-11 lasers but it was impossible because the crowd sizes were too big. The only way I think is If I had enough +HP upgrades and missile guns. However, there weren't any available in the shop. Therefore, it was a huge waste of time getting that far, in that very tedius map, only to be stuck. I didn't originally get the missile/mortars in the first campaign because the effects those guns were so f'king ugly.
Also, this game is buggy and is boring because it's so repetitive.
